Description

[0001] This application is a divisional application of the invention patent application filed on July 18, 2019, with application number 201980047651.7 and invention title "Bundling tape, binding method, tape roll and roll". Technical Field

[0002] This invention relates to binding tape, binding methods, tape rolls, and rolls. For example, it relates to binding tape, binding methods, tape rolls, and rolls that can be used in induced binding operations in crop cultivation. Background Technology

[0003] In the past, horticultural tying machines were used for tying and binding crops during cultivation. Specifically, for example, in the cultivation of crops such as cucumbers, grapes, and tomatoes, horticultural tying machines were used to tie the vines or stems of plants to supports or nets.

[0004] This garden tying machine, as shown in Patent Document 1, includes a main handle from which a strap can be pulled out from the front end, a clamping arm rotatable relative to the main handle, and an operating handle for rotating the clamping arm. When the operating handle of the garden tying machine is gently gripped, the clamping arm rotates in the closing direction relative to the main handle, and a strap holding device at the front end of the clamping arm holds the strap pulled out from the front end of the main handle. If the handle is released in this state, the clamping arm rotates in the opening direction relative to the main handle, pulling out the strap. With the strap pulled out and taut between the clamping arm and the main handle, crops and supports are pressed against the pulled-out strap, inserting them between the clamping arm and the main handle. If the handle is gripped again in this state, the clamping arm rotates in the closing direction relative to the main handle, forming a strap loop. If the handle is gripped further, the ends of the strap loop are secured with U-shaped staples, and the ends of the strap loop are cut off by a cutter, completing the tying process.

[0005] The binding tape used in such gardening binding machines is typically made of resin materials such as polyvinyl chloride (PVC) and polyethylene (PE). Furthermore, Patent Document 2 describes the use of non-woven fabric as the binding tape material.

[0006] Furthermore, Patent Document 3 describes a technique to prevent the adhesive tape from slipping along the winding axis and forming a mortar-like shape due to residual stress generated when pulling out the tape or deformation stress caused by temperature changes during storage. Thick paper is arranged side-by-side opposite the sides of the adhesive tape. This thick paper is glued only to the end face of the core of the adhesive tape and not to the sides, thus avoiding resistance when pulling out the tape. Furthermore, the thick paper prevents the adhesive tape from slipping along the winding axis.

[0007] Furthermore, Patent Document 4 describes a paper tube for winding yarn such as wool. This paper tube is shaped into a cone so that the yarn can be easily pulled out even after steaming and swelling.

[0008] Furthermore, Patent Document 5 describes a spool for winding electronic component strips to which electronic components are attached. This spool has two side plates made of plastic sheets facing each other, with protrusions formed protruding from the center of each side plate engaging with each other, thereby forming an outer peripheral surface for winding the electronic component strip.

[0014] Patent Document 4: Japanese Patent Publication No. 02-80669

[0015] Patent Document 5: Japanese Patent Publication No. 59-33867 Summary of the Invention

[0016] The problem that the invention aims to solve

[0017] However, the conventional binding straps described in Patent Documents 1 and 2 are prone to tearing when a force is applied to expand the strap loops, thus presenting a problem that they cannot be used for guiding operations on crops with branches or stems that have high repulsive forces.

[0018] For example, in the cultivation of fruit trees such as pears or plums, when branches are fixed to the fruit tree trellis, if the traditional tying machine and tying tape are used for tying, the tying tape will be pulled due to the repulsive force of the branches, and the tying tape will crack from the hole formed when it is fixed by the U-shaped nail, resulting in the problem of the tape loop falling off.

[0019] Therefore, when securing branches or other objects with high repulsive forces, the rope is tied manually using a high-strength guide rope (hemp rope, paper rope, ethylene rope, rubber tubing, etc.). This manual work is time-consuming and labor-intensive. Furthermore, the tying method is unique, making it difficult for unaccustomed workers to perform.

[0020] Therefore, the objective of this invention is to enable tying using a horticultural tying machine, even for crops with high repulsive forces.

[0021] Furthermore, unlike the adhesive tape described in Patent Document 3, the binding tape has the characteristic that the wound binding tapes easily unravel from each other. Therefore, even if the technology described in Patent Document 3 is applied to the binding tape, the binding tape will unravel in a direction perpendicular to the winding axis, i.e., in the outer diameter direction.

[0022] Therefore, the object of the present invention is to provide a strapping tape that is difficult to unravel even when used for binding objects, and even when it is a non-adhesive strapping tape without an adhesive layer.

[0023] Additionally, the spool is sometimes used by attaching it to branches or supports of various sizes (hereinafter referred to as "mandrels"). Patent documents 4 and 5 do not show a spool that can be properly supported on mandrels of various diameters.

[0024] Therefore, the object of the present invention is to provide a spool that can be appropriately supported on mandrels of various diameters.

[0025] Solution for solving the problem

[0026] The present invention is made to solve the above-mentioned problems and provides a strapping tape having an intermediate layer and a first surface layer covering one surface of the intermediate layer, characterized in that the intermediate layer has a plurality of first linear materials arranged side by side at an angle relative to the length direction of the strapping tape.

[0027] The present invention, as described above, comprises an intermediate layer and a first surface layer covering one surface of the intermediate layer. Furthermore, the intermediate layer has a plurality of first linear materials arranged side-by-side at an angle to the length direction of the binding tape. With this structure, when a force is applied to extend the binding tape along its length, the force to extend the binding tape also applies to the first linear materials. As a result, the strength of the binding tape is increased through the first linear materials, making it difficult to break even when U-shaped nails are driven into the binding tape. Using this binding tape, even for traction operations involving crops with high repulsive forces, binding operations can be performed using a horticultural binding machine.

[0028] Furthermore, a second surface layer may also be provided to cover the other surface of the intermediate layer. That is, it can also be a structure in which the intermediate layer is sandwiched between the first surface layer and the second surface layer.

[0029] Alternatively, the intermediate layer may have a second linear material that intersects with the first linear material. If configured in this way, the second linear material can suppress the widening of the spacing between the first linear materials, thus suppressing the elongation of the strapping tape. Consequently, even after the strapping tape is pulled following the insertion of U-shaped pins for binding, the holes pierced by the U-shaped pins are unlikely to widen, thus providing a strapping tape that is difficult to tear.

[0030] Alternatively, the first linear material can be arranged orthogonally to the length direction of the binding strap, and the second linear material can extend along the length direction of the binding strap. If configured in this way, the first and second linear materials form a grid pattern, thus increasing the strength of the binding strap.

[0031] Alternatively, the intermediate layer can be formed by weaving in the first and second linear materials. With this configuration, the surface of the intermediate layer becomes a flat sheet with minimal irregularities, making it easy to process even before the process of inserting it through the first and second surface layers, thus simplifying the manufacture of the strapping. Furthermore, because the first and second linear materials are intertwined, relative movement between them is difficult, effectively suppressing the elongation of the strapping.

[0032] Alternatively, at least one of the first and second linear materials can be formed by bundling fibrous raw materials. If configured in this way, even if the strength is increased by thickening the first or second linear material, the intermediate layer can remain thin. That is, when the intermediate layer is sandwiched between the first and second surface layers, the bundled fibrous raw material is flattened, thus reducing the thickness of the bundling tape.

[0033] Alternatively, the first linear materials can be arranged side by side at intervals of 5 mm or less. With this structure, even if the strapping is stretched after the U-shaped nails are driven in and the strapping is pulled, the legs of the U-shaped nails will abut against the first linear materials before stretching by at least 5 mm. This prevents further movement of the U-shaped nails and inhibits further expansion of the holes formed when the U-shaped nails are used for fixing.

[0034] Furthermore, at least one of the first and second surface layers can be formed from a photodegradable or biodegradable material. According to this structure, the binding tape can naturally deteriorate when left in the field after being bundled. Due to this surface layer deterioration, the binding tape becomes easy to remove during crop harvesting, and even if a detached binding tape falls into the field, it is difficult to notice.

[0035] It should be noted that the binding tape of the present invention can be used in a binding method in which the two ends of the binding tape are overlapped after being wound around the object to be bound, and a U-shaped pin is driven in, thereby binding the two ends together. In this binding method, the legs of the U-shaped pin are held by a first linear material, thereby inhibiting the movement of the U-shaped pin. Therefore, the hole pierced by the U-shaped pin is less likely to widen, and the binding tape is less likely to tear.

[0036] Furthermore, the binding tape of the present invention can be used in a binding method whereby, after the binding tape is wound around the object to be bound using a binding machine equipped with the binding tape, the two ends of the binding tape are overlapped and driven into a U-shaped pin, thereby binding the two ends together. In this binding method, the legs of the U-shaped pin are held by a first linear material, thereby suppressing the movement of the U-shaped pin, making it difficult for the hole piercing the U-shaped pin to widen, and preventing the binding tape from tearing.

[0037] Alternatively, a plurality of first slits separated along the length direction of the binding tape may be formed at one end of the intermediate layer of the binding tape in the width direction. Furthermore, a plurality of second slits separated along the length direction of the binding tape may be formed at the other end of the intermediate layer of the binding tape in the width direction. Moreover, at least one first slit may cut off at least a portion of the second linear material. Furthermore, the positions of the multiple first slits and the multiple second slits in the length direction may be asymmetrical with respect to a line passing through the center of the binding tape in the width direction. Furthermore, a slit that cuts off a portion of the first or second surface layer may be formed at a position corresponding to at least one first slit on the first or second surface layer. Furthermore, a slit that cuts off a portion of the first or second surface layer may be formed at a position corresponding to at least one second slit on the first or second surface layer. Furthermore, a slit that cuts off a portion of the second surface layer may be formed at a position corresponding to at least one first slit on the second surface layer. Furthermore, a slit that cuts off a portion of the second surface layer may be formed at a position corresponding to at least one second slit on the second surface layer. The length of at least one first slit in the width direction relative to the width of the binding tape may also be less than 15%. The first slit may also cut off more than 60% of the length of the second linear material in the width direction.

[0038] Additionally, the winding body includes: a cylindrical tubular member; a binding strap wound around the tubular member; and a first member located on the side of the wound binding strap and adhered to at least a portion of the side. However, the first member may also be flexible and capable of elastic deformation. Furthermore, the first member may form a hole communicating with a portion surrounded by the inner wall of the tubular member. Moreover, the inner diameter of the tubular member may be larger than the diameter of the hole. Furthermore, the tubular member may be formed as a cylinder extending along a direction passing through the central axis of the portion surrounded by the inner wall and the hole. Furthermore, the minimum distance (D2) between the tubular member and the central axis may be larger than the minimum distance (D1) between the first member and the central axis.

[0039] Furthermore, regarding the first member, the minimum distance (D2) between the tube member and the central axis can be at least 1 mm larger than the minimum distance (D1) between the first member and the central axis. Also, regarding the first member, the thickness (T) along the central axis direction of the portion where the minimum distance (D2) between the tube member and the central axis is larger than the minimum distance (D1) between the first member and the central axis can be at least 0.05 mm and less than 2 mm. Furthermore, the bonding area for bonding the first member to the side of the belt can decrease from the outer periphery of the wound belt towards the inner periphery. Moreover, the first member can also have an area where the bonding area of ​​the adhesive layer for bonding the first member to the side of the belt decreases from the outer periphery of the wound belt towards the inner periphery, and the adhesive layer is not exposed. Furthermore, at least a portion of the first member can be bonded to the tube member. Furthermore, a second member can also be provided, wherein one surface of the second member faces the end face of the tube member and a portion of the side of the belt, and the other surface faces the first member, and a second hole is formed communicating with the portion and hole surrounded by the tube member. Furthermore, the first and second holes may have approximately the same diameter, and the inner diameter of the tube member may be larger than the diameters of the first and second holes. The first member may also have a portion communicating with the portion surrounded by the inner wall of the tube member. Furthermore, the tube member may be formed as a cylinder extending along a central axis passing through the portion surrounded by the inner wall and the communicating portion, and the minimum distance (D2) between the tube member and the central axis may be larger than the minimum distance (D1) between the first member and the central axis. Moreover, the minimum distance (D2) between the tube member and the central axis may be at least 1 mm larger than the minimum distance (D1) between the first member and the central axis. Furthermore, regarding the first member, the thickness (T) of the portion where the minimum distance (D2) between the tube member and the central axis is set larger than the minimum distance (D1) between the first member and the central axis may be 0.05 mm or more and 2 mm or less.

[0040] The adhesive portion of the strapping tape to the first component may extend circumferentially along the strapping tape. The adhesive portion of the strapping tape to the first component may also extend radially along the strapping tape. Multiple adhesive portions of the strapping tape to the first component may also be provided separately from each other. The adhesive portion of the strapping tape to the first component may also extend in a spiral shape that travels both circumferentially and radially along the strapping tape.

[0041] Furthermore, in the tape winding body, the first member may also have a non-adhesive portion extending radially along the strapping tape but not bonded to the side of the strapping tape. Moreover, the first member may also have: a first portion including a part bonded to the tube member; and multiple portions bonded to the side of the strapping tape.

[0042] Furthermore, the roll has: a cylindrical tube member for winding with strapping tape; and a protrusion that protrudes from the inner wall of the tube member or from one end face of the tube member toward the axis of the tube member and is flexible.

[0043] The protrusion may also be located within a range W of ±5.5 mm from the center position of the inner wall portion in the axial direction. Alternatively, one end face of the pipe member may be connected to the other end face, and the protrusion P of the protrusion may be 1 mm or more. The maximum thickness T of the protrusion in the axial direction may also be 0.05 mm or more and 2 mm or less. The protrusion may also be a membrane protruding from one end face of the pipe member toward the axial side of the pipe member. The membrane may also have a double-layer structure. Furthermore, the protrusion may also possess at least one of water resistance and ductility.

[0044] In addition, the tape winding body includes: a strapping tape; a roll having a cylindrical tube member on which the strapping tape is wound, a flexible protrusion protruding from the inner wall of the tube member or from one end face of the tube member toward the axis of the tube member; and a first member located on the side of the wound strapping tape and bonded to at least a portion of the side.

[0045] Here, the adhesive portion between the strapping tape and the first component may extend circumferentially along the strapping tape. Furthermore, the adhesive portion between the strapping tape and the first component may extend radially along the strapping tape. Multiple adhesive portions between the strapping tape and the first component may also be provided separately. Moreover, the adhesive portion between the strapping tape and the first component may extend in a spiral shape that travels both circumferentially and radially along the strapping tape.

[0046] Furthermore, in the tape winding, the first member may also have a non-adhesive portion extending radially along the strapping tape without being bonded to the side of the strapping tape. Moreover, the first member may also have: a first portion including a part bonded to the tube member; and multiple portions bonded to the side of the strapping tape. Alternatively, the first member may have a first portion including a part bonded to the tube member, and further, on an imaginary circle centered on the axis of the tube member and containing the first portion, a first arcuate portion bonded to the side of the strapping tape and a second arcuate portion not bonded to the side of the strapping tape.

[0047] Furthermore, this disclosure relates to a tape winding body. The tape winding body includes a cylindrical tubular member, a tape wound around the tubular member and capable of binding an object, and a first member located on the side of the wound tape, wherein at least a portion of the first member is bonded to the side of the tape. Here, the first member may also be configured to be flexible and capable of elastic deformation.

[0048] Alternatively, the first member may have a hole communicating with a portion surrounded by the inner wall of the tube member. On the other hand, the first member may only have a cut. The user may then press the first member open along this cut. Furthermore, the first member may not have a hole or cut. The user may then puncture a portion of the first member.

[0049] Furthermore, the inner diameter of the tube member is preferably larger than the diameter of the hole. Moreover, the tube member can be formed in a cylindrical shape extending along the central axis of the portion surrounded by the inner wall and the hole. Furthermore, the hole is preferably formed such that the minimum distance (D2) between the inner wall surface of the tube member and the central axis is greater than the minimum distance (D1) between the first member and the central axis. More preferably, the minimum distance (D2) between the inner wall surface of the tube member and the central axis is at least 1 mm greater than the minimum distance (D1) between the first member and the central axis.

[0050] Furthermore, regarding the first member, the thickness (T) along the central axis of the portion where the minimum distance (D2) between the tube member and the central axis is greater than the minimum distance (D1) between the first member and the central axis is preferably 0.05 mm or more and 2 mm or less.

[0051] Furthermore, the bonding area for adhering the first member to the side of the strip can be reduced from the outer periphery of the wound strip toward the inner periphery. Additionally, a second member may be provided, one surface of which faces the surface of the tube member and a portion of the side of the strip, while the other surface is disposed opposite to the first member, and a second hole is formed communicating with the space and hole surrounded by the tube member. Here, the hole and the second hole may also have approximately the same diameter, with the inner diameter of the tube member being larger than the diameter of the hole and the second hole.

[0052] Furthermore, this disclosure relates to a tape winding body having a tape capable of binding two or more objects. The tape winding body comprises: a cylindrical tubular member; a tape wound around the tubular member and capable of binding the objects; and a first member bonded to the side of the wound tape, having a hole communicating with a portion surrounded by the inner wall of the tubular member. It should be noted that the first member may also have an area where the adhesive area of ​​the adhesive layer bonding the first member to the side of the tape decreases from the outer periphery of the wound tape towards the inner periphery, and the adhesive layer is not exposed.

[0053] Furthermore, this disclosure relates to a tape winding body having a tape capable of binding the bound object. The tape winding body comprises: a cylindrical tube member; a tape wound around the tube member; and a first member, which is bonded to the side of the wound tape and forms a hole communicating with a portion surrounded by the inner wall of the tube member.

[0054] In such a wrapped tape, multiple first slits separated along the length of the binding tape may be formed at one end of the intermediate layer of the binding tape in the width direction. Furthermore, multiple second slits separated along the length of the binding tape may be formed at the other end of the intermediate layer of the binding tape in the width direction. Moreover, at least one first slit may cut off at least a portion of the second linear material. Furthermore, the positions of the multiple first slits and the multiple second slits in the length direction may be asymmetrical with respect to a line passing through the center of the binding tape in the width direction. Furthermore, a slit cutting off a portion of the first or second surface layer may be formed at a position corresponding to at least one first slit on the first or second surface layer. Furthermore, a slit cutting off a portion of the first or second surface layer may be formed at a position corresponding to at least one second slit on the first or second surface layer. Furthermore, a slit cutting off a portion of the second surface layer may be formed at a position corresponding to at least one first slit on the second surface layer. Furthermore, a slit cutting off a portion of the second surface layer may be formed at a position corresponding to at least one second slit on the second surface layer. The length of at least one first slit in the width direction relative to the width of the binding tape may also be less than 15%. The first slit may also cut off more than 60% of the length of the second linear material in the width direction.

[0055] In such a wrapped tape, the binding tape may also have an intermediate layer and a first surface layer covering one surface of the intermediate layer. The intermediate layer is characterized by having a plurality of first linear materials arranged side-by-side at an angle to the length direction of the binding tape.

[0056] The present invention, as described above, comprises an intermediate layer and a first surface layer covering one surface of the intermediate layer. Furthermore, the intermediate layer has a plurality of first linear materials arranged side-by-side at an angle to the length direction of the binding tape. With this structure, when a force is applied to extend the binding tape along its length, the force also applies to the first linear materials. Thus, the strength of the binding tape is increased through the first linear materials, making it difficult to break even when U-shaped nails are driven into the binding tape for binding. Using this binding tape, even for traction operations involving crops with high repulsive forces, binding operations can be performed using a horticultural binding machine.

[0057] It should be noted that a second surface layer may also be included to cover the other surface of the intermediate layer. That is, it can also be a structure in which a first surface layer and a second surface layer are sandwiched between the intermediate layer.

[0058] Alternatively, the intermediate layer may have a second linear material that intersects with the first linear material. If configured in this way, the widening of the spacing between the first linear materials due to the second linear material can be suppressed, thus preventing the strapping from elongating. Consequently, even if the strapping is pulled after being secured with U-shaped pins, the holes pierced by the U-shaped pins are difficult to expand, thus providing a strapping that is difficult to tear.

[0059] Alternatively, the first linear material can be arranged orthogonally to the length direction of the binding strap, and the second linear material can extend along the length direction of the binding strap. If configured in this way, the first and second linear materials form a grid pattern, thus increasing the strength of the binding strap.

[0060] Alternatively, the intermediate layer can be formed by weaving in the first and second linear materials. If configured in this way, the surface of the intermediate layer becomes a flat sheet without any bumps or depressions, making it easy to process before the insertion of the first and second surface layers, thus simplifying the manufacture of the strapping. Furthermore, because the first and second linear materials are intertwined, relative movement between them is difficult, effectively suppressing the elongation of the strapping.

[0061] Alternatively, at least one of the first and second linear materials can be formed by bundling fibrous raw materials. If configured in this way, the intermediate layer will not become thicker even if the strength is increased by thickening the first or second linear material. That is, when the intermediate layer is sandwiched between the first and second surface layers, the linear material bundling the fibrous raw materials is flattened, thus reducing the thickness of the bundling tape.

[0062] Alternatively, the first linear materials can be arranged side-by-side at intervals of 5 mm or less. With this structure, even if the strapping is stretched after the U-shaped nails are driven in and secured, the legs of the U-shaped nails will remain in contact with the first linear materials until the stretch reaches at least 5 mm. This prevents further movement of the U-shaped nails and inhibits further expansion of the holes formed during U-shaped nail fixation.

[0063] Furthermore, at least one of the first and second surface layers can be formed of a photodegradable or biodegradable material. With this structure, the binding tape can naturally degrade when placed in the field. Due to this surface layer degradation, the binding tape is easy to remove during crop harvesting, and even if it falls into the field, it remains inconspicuous.

[0064] It should be noted that the binding tape of the present invention can be used in a binding method in which the two ends of the binding tape are overlapped after being wound around the object to be bound, and a U-shaped pin is driven in, thereby binding the two ends together. In this binding method, the legs of the U-shaped pin are held by a first linear material, thereby inhibiting the movement of the U-shaped pin. Therefore, the hole pierced by the U-shaped pin is less likely to widen, and the binding tape is less likely to tear.

[0065] Furthermore, the binding tape of the present invention can be used in a binding method whereby, after the binding tape is wound around the object to be bound using a binding machine equipped with the binding tape, the two ends of the binding tape are overlapped and driven into a U-shaped pin, thereby binding the two ends together. In this binding method, the legs of the U-shaped pin are held by a first linear material, thereby suppressing the movement of the U-shaped pin, making it difficult for the hole piercing the U-shaped pin to widen, and preventing the binding tape from tearing.

[0066] Here, the adhesive portion between the strapping tape and the first component may extend circumferentially along the strapping tape. Furthermore, the adhesive portion between the strapping tape and the first component may extend radially along the strapping tape. Multiple adhesive portions between the strapping tape and the first component may also be provided separately. Moreover, the adhesive portion between the strapping tape and the first component may extend in a spiral shape that travels both circumferentially and radially along the strapping tape.

[0067] Furthermore, in the tape winding body, the first member may also have a non-adhesive portion extending radially along the strapping tape but not bonded to the side of the strapping tape. Moreover, the first member may also have: a first portion including a part bonded to the tube member; and multiple portions bonded to the side of the strapping tape. Alternatively, the first member may have a first portion including a part bonded to the tube member, and further, on an imaginary circle centered on the axis of the tube member and containing the first portion, a first arcuate portion bonded to the side of the strapping tape and a second arcuate portion not bonded to the side of the strapping tape.

[0068] This disclosure relates to a reel comprising: a cylindrical tubular member capable of being wound with a strap for binding an object; and a protrusion that protrudes from the inner wall of the tubular member or from one end face toward the axial side of the tubular member and is flexible. Alternatively, a strap that is wound around the tubular member for binding an object may also be included.

[0069] Based on this structure, since the protrusion is flexible, when a rod-shaped component such as a tree branch is inserted into the pipe component, the protrusion flexes, which can achieve a backflow prevention effect that makes it difficult for the rod-shaped component to fall off in the pull-out direction.

[0070] The protrusion is preferably located within a range W of ±5.5 mm from the center of the inner wall in the axial direction.

[0071] With this structure, when a rod-shaped component such as a tree branch is inserted into the pipe component, the protrusion bends appropriately due to the engagement between the rod-shaped component and the pipe component, and the drum is stably supported without excessive tilting.

[0072] Furthermore, the maximum thickness T in the axial direction is preferably 0.05 mm or more and 2 mm or less. Additionally, the protrusion may be a membrane protruding from one end face of the tube member toward the axial side of the tube member.

[0073] Based on this structure, since the protrusions are provided as a membrane, they can be easily provided on the pipe member. Furthermore, the protrusion amount P and maximum thickness T can be easily adjusted by adjusting the shape of the membrane. Moreover, the protrusions can be provided using a material with different physical properties (including elastic modulus) than the pipe member. It should be noted that the membrane can also be a double-layer structure.

[0074] By designing the membrane as a double-layer structure, it becomes easier to adjust the protrusion amount P and the maximum thickness T according to the application. Furthermore, by designing it as a double-layer structure, when the first component is adhered to the end face of the tube component, even if the adhesive or other substances are exposed at the protruding part of the first component, the second component can cover the adhesive or adhesive. When inserting a rod-shaped component such as a branch into the tube component and pulling out the tape, it is possible to prevent exposed adhesive or adhesive from becoming a resistance and causing adverse effects. It should be noted that the double-layer structure includes multi-layer structures with three or more layers.

[0075] The pipe component is preferably connected to one end face and the other end face, and the protrusion P of the protrusion is more than 1 mm.

[0076] When the protrusion is set within the range of the above values, the protrusion flexes when a rod-shaped member such as a tree branch is inserted into the tube member and the belt is pulled out, thus obtaining an appropriate braking force.

[0077] Furthermore, the protrusion may also be formed by a first member, the surface of which faces one end face of the tube member and extends toward the axial side of the tube member. Additionally, a second member may also be provided, one surface of which faces one end face of the tube member, and the other surface of which faces the first member and extends toward the axial side of the tube member. Here, a hole may also be formed in the first member that communicates with a portion surrounded by the inner wall of the tube member.

[0078] Furthermore, in a cross-section including the axis, the connection point that connects to the protrusion at a first contact point at the front end of the protrusion and to the pipe member at a second contact point on the other end face of the pipe member can be formed with the protrusion inclined relative to a straight line including the axis. The inclination angle is preferably, for example, 3 degrees or more.

[0079] Furthermore, this disclosure relates to a reel equipped with a strap capable of binding bundled objects. The reel includes a tubular member, a strap wound around the tubular member, and a protrusion extending from one end face of the tubular member toward its axial direction. In a cross-section including the axial direction, a connection is formed at a first contact point at the front end of the protrusion and at a second contact point on the other end face of the tubular member, inclined relative to a straight line including the axial direction. The angle of inclination is preferably 3 degrees or more.

[0080] Furthermore, this disclosure relates to a reel having a coiled, cylindrical tubular member capable of binding bundled objects. Here, at least one end of the tubular member in the axial direction may have a first protrusion extending from the inner wall of the tubular member toward the axial side in a first cross-section including the axial center, and at the same end, in a second cross-section different from the first cross-section including the axial center, a second protrusion extending from the inner wall of the tubular member toward the axial center. However, it may also be an annular protrusion where the first and second protrusions are integrally formed. On the other hand, the first and second protrusions may be formed separately in the circumferential direction centered on the axial center. In this case, no protrusion protruding from the inner wall is formed in a third cross-section including the axial center. Moreover, the protrusion is preferably configured such that the end near the axial center is formed as a free end, and it can deform in either direction in the axial direction (the direction toward the other end in the axial direction and its opposite direction). Preferably, the deformation is elastic deformation, that is, the protrusion is formed by returning to its original shape in size and material when the force causing the deformation disappears.

[0081] The reel may also have a strap that can be wound around the pipe component to bind the object being bound.

[0082] In a strip winding with a strapping material wound around a tubular member, multiple first slits separated along the length of the strapping material can be formed at one end of the intermediate layer of the strapping material in the width direction. Furthermore, multiple second slits separated along the length of the strapping material can be formed at the other end of the intermediate layer of the strapping material in the width direction. Moreover, at least one first slit in the second linear material can cut off at least a portion of the second linear material. Furthermore, the positions of the multiple first slits and the multiple second slits along their length directions can be asymmetrical relative to a line passing through the center of the strapping material in the width direction. Furthermore, a slit that cuts off a portion of the first or second surface layer can be formed at a position corresponding to at least one first slit in the first or second surface layer. Furthermore, a slit that cuts off a portion of the first or second surface layer can be formed at a position corresponding to at least one second slit in the first or second surface layer. Furthermore, a slit that cuts off a portion of the second surface layer can be formed at a position corresponding to at least one first slit in the second surface layer. Furthermore, a slit that cuts off a portion of the second surface layer can be formed at a position corresponding to at least one second slit in the second surface layer. The length of at least one first slit in the width direction relative to the width of the binding tape may also be less than 15%. The first slit may also cut off more than 60% of the length of the second linear material in the width direction.

[0083] Such a roll, as a tape winding body, comprises a cylindrical tube member, a tape wound around the tube member and capable of binding the bound object, and a first member located on the side of the wound tape, wherein at least a portion of the first member is bonded to the side of the tape. Here, the first member may also be configured to be flexible and capable of elastic deformation.

[0084] Alternatively, the first member may have a hole communicating with the portion surrounded by the inner wall of the tube member. On the other hand, the first member may only have a cut. The user may then press the first member open along this cut. Furthermore, the first member may not have a hole or cut. The user may then puncture a portion of the first member.

[0085] Furthermore, the inner diameter of the tube member is preferably larger than the diameter of the hole. Moreover, the tube member can also be formed in a cylindrical shape, extending along the direction passing through the portion surrounded by the inner wall and the central axis of the hole. Furthermore, the hole is preferably formed such that the minimum distance (D2) between the inner wall surface of the tube member and the central axis is larger than the minimum distance (D1) between the first member and the central axis. More preferably, the minimum distance (D2) between the inner wall surface of the tube member and the central axis is at least 1 mm larger than the minimum distance (D1) between the first member and the central axis.

[0086] Furthermore, the thickness (T) along the central axis of the portion where the minimum distance (D2) between the first component and the central axis is greater than the minimum distance (D1) between the first component and the central axis is 0.05 mm or more and 2 mm or less.

[0087] Furthermore, the bonding area for adhering the first member to the side of the strip can be reduced from the outer periphery of the wound strip toward the inner periphery. Additionally, a second member may be provided, one surface of which faces the surface of the tube member and a portion of the side of the strip, while the other surface is disposed opposite to the first member, forming a second hole communicating with the space and opening surrounded by the tube member. Here, the hole and the second hole may also have approximately the same diameter, with the inner diameter of the tube member being larger than the diameter of the hole and the second hole.

[0088] Furthermore, this disclosure relates to a tape winding body having a tape capable of binding two or more objects. The tape winding body comprises: a cylindrical tubular member; a tape wound around the tubular member and capable of binding the objects; and a first member bonded to the side of the wound tape and having a hole formed communicating with a portion surrounded by the inner wall of the tubular member. It should be noted that the first member may also have an area where the adhesive area of ​​the adhesive layer bonding the first member to the side of the tape decreases from the outer periphery of the wound tape towards the inner periphery, and the adhesive layer is not exposed.

[0089] Furthermore, this disclosure relates to a tape winding body capable of binding objects with a tape. The tape winding body comprises: a cylindrical tube member; a tape wound around the tube member; and a first member bonded to the side of the wound tape and having a hole communicating with a portion surrounded by the inner wall of the tube member.

[0090] In such a roll or strip winding, the strapping tape may also have an intermediate layer and a first surface layer covering one surface of the intermediate layer. The intermediate layer is characterized by having a plurality of first linear materials arranged side-by-side at an angle to the length direction of the strapping tape.

[0091] The present invention, as described above, comprises an intermediate layer and a first surface layer covering one surface of the intermediate layer. Furthermore, the intermediate layer has a plurality of first linear materials arranged side-by-side at an angle to the length direction of the binding tape. With this structure, when a force is applied to extend the binding tape along its length, the force also applies to the first linear materials. Thus, the strength of the binding tape is increased through the first linear materials, making it difficult to break even when U-shaped nails are driven into the binding tape for binding. Using this binding tape, even for traction operations involving crops with high repulsive forces, binding operations can be performed using a horticultural binding machine.

[0092] It should be noted that a second surface layer may also be included to cover the other surface of the intermediate layer. That is, it can also be a structure in which the intermediate layer is sandwiched between the first surface layer and the second surface layer.

[0093] Alternatively, the intermediate layer may have a second linear material that intersects with the first linear material. If configured in this way, the widening of the spacing between the first linear materials due to the second linear material can be suppressed, thus preventing the strapping from elongating. Consequently, even if the strapping is pulled after being secured with U-shaped pins, the holes pierced by the U-shaped pins are difficult to expand, thus providing a strapping that is difficult to tear.

[0094] Alternatively, the first linear material can be arranged orthogonally to the length direction of the binding strap, and the second linear material can extend along the length direction of the binding strap. If configured in this way, the first and second linear materials form a grid pattern, thus increasing the strength of the binding strap.

[0095] Alternatively, the intermediate layer can be formed by weaving in the first and second linear materials. If configured in this way, the surface of the intermediate layer becomes a flat sheet with few irregularities, making it easy to process before the insertion of the first and second surface layers, thus simplifying the manufacture of the strapping. Furthermore, because the first and second linear materials are intertwined, relative movement between them is difficult, effectively suppressing the elongation of the strapping.

[0096] Alternatively, at least one of the first and second linear materials can be formed by bundling fibrous raw materials. If configured in this way, the intermediate layer will not become thicker even if the strength is increased by thickening the first or second linear material. That is, when the intermediate layer is sandwiched between the first and second surface layers, the linear material bundling the fibrous raw materials is flattened, thus reducing the thickness of the bundling tape.

[0097] Alternatively, the first linear materials can be arranged side-by-side at intervals of 5 mm or less. With this structure, even if the strapping is stretched after the U-shaped nails are driven in and secured, the legs of the U-shaped nails will remain in contact with the first linear materials until the stretch reaches at least 5 mm. This prevents further movement of the U-shaped nails and inhibits further expansion of the holes formed during U-shaped nail fixation.

[0098] Furthermore, at least one of the first and second surface layers can be formed of a photodegradable or biodegradable material. With this structure, the binding tape can naturally degrade when placed in the field. Due to this surface layer degradation, the binding tape is easy to remove during crop harvesting, and even if it falls into the field, it remains inconspicuous.

[0099] It should be noted that the binding tape of the present invention can be used in a binding method whereby the binding tape is wound around the object to be bound, the two ends of the binding tape are overlapped, and a U-shaped pin is driven in, thereby binding the two ends together. In this binding method, the legs of the U-shaped pin are held by a first linear material, thereby inhibiting the movement of the U-shaped pin. Therefore, the hole pierced by the U-shaped pin is less likely to widen, and the binding tape is less likely to tear.

[0100] Furthermore, the binding tape of the present invention can be used in a binding method whereby, after the binding tape is wound around the object to be bound using a binding machine equipped with the binding tape, the two ends of the binding tape are overlapped and driven into a U-shaped pin, thereby binding the two ends together. In this binding method, the legs of the U-shaped pin are held by a first linear material, thereby suppressing the movement of the U-shaped pin, making it difficult for the hole piercing the U-shaped pin to widen, and preventing the binding tape from tearing.

[0286] 142. In the coiled body described in 108 or 109, the characteristic is that,

[0287] The first member has a portion that communicates with a portion surrounded by the inner wall of the tube member.

[0288] 143. In the coiled body described in 142, the characteristic is that,

[0289] The tubular member is formed as a cylinder extending along a central axis passing through the portion surrounded by the inner wall and the communicating portion, and the minimum distance (D2) between the tubular member and the central axis is greater than the minimum distance (D1) between the first member and the central axis.

[0290] 144. In the coiled body described in 143, the characteristic is that,

[0291] The minimum distance (D2) between the tubular component and the central axis is more than 1 mm greater than the minimum distance (D1) between the first component and the central axis.

[0293] Regarding the first component, the thickness (T) of the portion where the minimum distance (D2) between the tube component and the central axis is set to be greater than the minimum distance (D1) between the first component and the central axis is 0.05 mm or more and 2 mm or less.

[0294] 146. In the coiled body described in 108,

[0295] The first component comprises: a first portion including a portion that is bonded to the tube component; and a second portion including a portion that extends radially along the strapping tape and is bonded to the side of the strapping tape.

[0296] 147. In the coiled body described in 146,

[0297] The first member has a non-adhesive portion that extends radially along the strapping tape but is not adhered to the side of the strapping tape.

[0298] 148. In the coiled body described in 108,

[0299] The first component includes: a first portion comprising a part that is bonded to the tube component; and multiple portions that are bonded to the side of the strapping tape.

[0302] The topics corresponding to Note A (Notes 1 to 38) and Note B (Notes 101 to 149) mentioned above are described below.

[0303] Patent document 3 describes a technique to prevent the adhesive tape from slipping along the winding axis and forming a mortar-like shape due to residual stress generated when pulling out the tape or deformation stress caused by temperature changes during storage. Thick paper is arranged side-by-side opposite the sides of the adhesive tape. This thick paper is glued only to the end face of the core of the adhesive tape and not to the sides, thus avoiding resistance when pulling out the tape. Furthermore, the thick paper prevents the adhesive tape from slipping along the winding axis.

[0304] Furthermore, Patent Document 4 describes a paper tube for winding yarn such as wool. This paper tube is shaped into a cone so that the yarn can be easily pulled out even after steaming and swelling.

[0305] Furthermore, Patent Document 5 describes a spool for winding electronic component strips to which electronic components are attached. This spool has two side plates made of plastic sheets facing each other, with protrusions formed from the center of each side plate engaging with each other, thereby forming an outer peripheral surface for winding the electronic component strip.

[0306] However, the binding tape differs from the adhesive tape described in Patent Document 3, having the characteristic that the wound binding tapes easily unravel from each other. Therefore, even if the technology described in Patent Document 3 is applied to the binding tape, the binding tape will unravel in a direction perpendicular to the winding axis, that is, along the outer diameter direction.

[0307] Therefore, the subject of the invention described as an appendix is ​​to provide a wrapping material that is difficult to unravel, even for wrapping materials used to bind objects, and even for non-adhesive wrapping materials without an adhesive layer.

[0308] Additionally, the spool is sometimes used by attaching it to branches or supports of various sizes (hereinafter referred to as "mandrels"). Patent documents 4 and 5 do not show a spool that can be properly supported on mandrels of various diameters.

[0309] Therefore, the subject of the invention described as an appendix is ​​to provide a spool that can be properly supported on mandrels of various diameters. Attached Figure Description

[0373] The embodiments of the present invention will be described with reference to the accompanying drawings.

[0374] [First Implementation Method]

[0375] The binding strap 10 of this embodiment is a structure used for binding the object 40, for example, in the traction binding operation when cultivating crops. Specifically, it is used to bind the vines, stems, branches, etc. of plants to supports, nets, trellises, etc. This binding strap 10 is usually installed on a binding machine 20 (described later), such as... Figure 1 It is shown to be loaded into the tape box 26 of the strapping machine 20 in the state of being wound on the core 19.

[0376] like Figure 2 As shown, the strapping tape 10 has an intermediate layer 11, a first surface layer 16 covering one surface of the intermediate layer 11, and a second surface layer 17 covering the other surface of the intermediate layer 11.

[0377] In this embodiment, the intermediate layer 11 is composed of multiple linear materials. Specifically, it is composed of a first linear material 12 and a second linear material 13.

[0378] Multiple first linear materials 12 are arranged side-by-side at an angle relative to the length direction of the binding tape 10. In this embodiment, the first linear materials 12 are arranged orthogonally to the length direction D1 of the binding tape 10. In other words, the first linear materials 12 extend along the width direction D2 of the binding tape 10.

[0379] These multiple first linear materials 12 are arranged side by side at predetermined intervals. The interval W1 of the first linear materials 12 is preferably 5 mm or less (less than the length of the crown 32 of the U-shaped nail 30 used for binding), more preferably 3 mm or less (less than the length of the leg 31 of the U-shaped nail 30 used for binding). With this structure, even if the binding strap 10 is pulled and stretched after the U-shaped nail 30 is inserted and bound, the leg 31 of the U-shaped nail 30 will abut against the first linear materials 12 before stretching by at least 5 mm (or 3 mm), thus preventing further movement of the U-shaped nail 30 and suppressing further expansion of the hole formed during fixing with the U-shaped nail 30. The size of the expanded hole is suppressed to not exceed the length of the crown 32 (or the length of the leg 31) of the U-shaped nail 30 used for binding, thereby making it difficult for the U-shaped nail 30 to fall off.

[0380] On the other hand, the second linear material 13 is arranged to intersect with the first linear material 12. In this embodiment, the second linear material 13 extends along the length direction D1 of the binding tape 10. In other words, the second linear material 13 is arranged orthogonally to the width direction D2 of the binding tape 10.

[0381] Furthermore, in this embodiment, multiple second linear materials 13 are arranged side by side at predetermined intervals. The arrangement interval of these second linear materials 13 is set to be the same as the arrangement interval of the first linear materials 12.

[0382] It should be noted that in this embodiment, multiple second linear materials 13 are arranged side by side, but this is not a limitation; only one may be used. However, if it is desired to increase the strength of the binding tape 10, it is preferable to use multiple second linear materials 13. Furthermore, when the U-shaped nail 30 is driven in, at least one second linear material 13 passes between a pair of legs 31 of the U-shaped nail 30, thereby making the binding tape 10 less likely to break.

[0383] The aforementioned first linear material 12 and second linear material 13 are formed by bundling (twisting) fiber raw materials made of polyester resins such as polyethylene terephthalate (PET). By bundling the fiber raw materials in this way, even if the strength is increased by thickening the first linear material 12 or the second linear material 13, the thickness of the intermediate layer 11 can be avoided. That is, when the intermediate layer 11 is sandwiched in using the first surface layer 16 and the second surface layer 17, the first linear material 12 and the second linear material 13 are flattened, thus reducing the thickness of the bundling tape 10.

[0384] In addition, the first linear material 12 and the second linear material 13 are as follows Figure 3 The intermediate layer 11 is formed by interlacing the materials in a grid pattern. By forming the intermediate layer 11 into a sheet shape, it is easy to process even before the processing involving the insertion of the first surface layer 16 and the second surface layer 17, which is advantageous for the manufacture of the strapping tape 10. Furthermore, because the first linear material 12 and the second linear material 13 are intertwined, they are difficult to move due to friction, thus preventing the grid gaps from widening and effectively suppressing the elongation of the strapping tape 10.

[0385] It should be noted that the first thread material 12 and the second thread material 13 do not necessarily need to be woven in alternately. For example, the first thread material 12 and the second thread material 13 can be layered in a crisscross pattern, and the first thread material 12 and the second thread material 13 can be woven in one strand at a time, rather than alternating. Moreover, the first thread material 12 and the second thread material 13 can be woven in instead of the first thread material 12 and the second thread material 13. In this case, the first thread material 12 and the second thread material 13 are less likely to come apart.

[0386] The first surface layer 16 and the second surface layer 17 are formed from film-like resin raw materials (polyvinyl chloride (PVC), polyethylene (PE), etc.) to provide weather resistance. The intermediate layer 11 is sandwiched in the first surface layer 16 and the second surface layer 17 and the first surface layer 16 and the second surface layer 17 are bonded together to form the strapping tape 10.

[0387] The binding tape 10 is used in, for example Figure 4 and Figure 5 This is used in a strapping machine 20 as shown. This strapping machine 20 is similar to known strapping machines. That is, the strapping machine 20 includes: a linearly formed, slender main handle 21; a clamping arm 23 mounted to rotate relative to the main handle 21; and an operating handle 25 mounted to rotate relative to the clamping arm 23. The clamping arm 23 is constantly stressed by a spring, and under normal conditions... Figure 4 This is the open position relative to the main handle 21. From this position, grip the operating handle 25 and the main handle 21, thereby... Figure 5 As shown, the clamping arm 23 rotates relative to the main handle 21 in the closing direction.

[0388] It should be noted that a strap box 26 for accommodating the strapping strap 10 is provided at the rear of the main handle 21. The strapping strap 10, housed in the strap box 26, is pulled out through the interior of the main handle 21 to the front end 21a of the main handle 21. The front end 21a of the main handle 21 is positioned to maintain the front end of the strapping strap 10.

[0389] Additionally, a U-shaped nail box 22 for accommodating the U-shaped nail 30 is provided on the main handle 21. The U-shaped nail 30 used in this embodiment is... Figure 6 As shown, it has a general U-shape and includes a pair of legs 31 and a crown 32 connecting the pair of legs 31. The U-shaped nails 30 housed in the U-shaped nail box 22 use a structure that joins multiple U-shaped nails 30 together with adhesive or the like. The U-shaped nails 30 housed in the U-shaped nail box 22 are sequentially conveyed in the forward direction for use in securing the binding tape 10.

[0390] A U-shaped nail insertion tool (not shown) for discharging U-shaped nails 30 is provided near the front end of the U-shaped nail box 22. When the clamping arm 23 is rotated to the fully closed state relative to the main handle 21, the U-shaped nail insertion tool enters the U-shaped nail box 22 and discharging the foremost U-shaped nail 30 from the box. The legs 31 of the discharging U-shaped nail 30 are pressed inward by the clamps (not shown) provided at the front end 23a of the clamping arm 23.

[0391] Additionally, a cutting blade (not shown) is provided at the front end 21a of the main handle 21 for cutting the strapping band 10 after it has been tied.

[0392] Additionally, a strap gripping part 24 is provided at the front end 23a of the clamping arm 23, which is used to grip the strap 10 that is pulled out to the front end 21a of the main handle 21.

[0393] When using the strapping machine 20 to strap the object 40, first grip the operating handle 25 to rotate the clamping arm 23 in the closing direction relative to the main handle 21. This causes the strap gripping part 24, located at the front end 23a of the clamping arm 23, to grasp the strapping tape 10 that has been pulled out to the front end 21a of the main handle 21. Then, when the operating handle 25 is released and the clamping arm 23 is rotated in the opening direction relative to the main handle 21, the front end 23a of the clamping arm 23 separates from the front end 21a of the main handle 21 while holding the strapping tape 10, resulting in the strapping tape 10 being taut between the clamping arm 23 and the main handle 21. The object 40 is then placed outside the taut strapping tape 10, and the operating handle 25 is gripped again to rotate the clamping arm 23 in the closing direction relative to the main handle 21. When the front end 23a of the clamping arm 23 and the front end 21a of the main handle 21 are pressed together by this action, the two ends of the strapping tape 10 wrapped around the object to be bound 40 overlap, forming a loop for binding the object to be bound 40. Then, a U-shaped nail 30 is driven out using a U-shaped nail driving tool, and the legs 31 of the driven-out U-shaped nail 30 are driven into the vicinity of the overlapping loop and penetrate through it. The legs 31 of the U-shaped nail 30 that penetrate through the loop are pressed against the clamping clamp and secured. Then, the strapping tape 10 is cut off by cutting the secured loop. Thus, the strapping tape 10 is pulled out in the first gripping action, and binding is performed in the second gripping action. In this way, the strapping machine 20 of this embodiment can perform binding by driving the U-shaped U-shaped nail 30 into the two ends of the strapping tape 10 wrapped around the object to be bound 40. Figure 7 The binding is as shown.

[0394] Here, during the aforementioned binding action, when inserting the U-shaped nails 30 into the binding tape 10, firstly as follows... Figure 8 (a) shows the U-shaped nail 30's legs 31 penetrating and piercing near both ends of the overlapping binding tape 10. Then, as shown... Figure 8 As shown in (b), the leg 31 of the U-shaped nail 30 is twisted and bent inward. Thus, as Figure 10 As shown in (a), the overlapping binding strap 10 is held in place by the legs 31 and crown 32 of the U-shaped nail 30.

[0395] In this binding method that uses U-shaped nails 30 to secure the strapping tape 10, holes are inevitably created in the strapping tape 10 because the legs 31 of the U-shaped nails 30 pierce into the strapping tape 10. When such a strapping tape 10 is pulled, stress is concentrated at the holes formed when it is secured with U-shaped nails 30. Therefore, in conventional binding methods using strapping tape 10', such as... Figure 13 As shown, there is a situation where the strapping tape 10' breaks through the hole formed when it is fixed with U-shaped nails 30.

[0396] Regarding this point, if the strapping tape 10 of this embodiment is used, when the leg 31 of the U-shaped nail 30 is pierced into the strapping tape 10, as... Figure 9 As shown in (a), the legs 31 of the U-shaped stud 30 extend between a plurality of first linear materials 12. Furthermore, at least one second linear material 13 passes through the legs 31 of the U-shaped stud 30. In this state... Figure 9 (b) When the leg 31 of the U-shaped nail 30 is bent, the leg 31 of the U-shaped nail 30 is held in the gap between the first thread material 12 and the second thread material 13 woven in a grid pattern.

[0397] In this binding state, even if the binding strap 10 is pulled, the movement of the U-shaped nail 30 can be suppressed by using the first linear material 12 to hold the legs 31 of the U-shaped nail 30. Therefore, the hole pierced by the U-shaped nail 30 is difficult to expand, and the binding strap 10 is difficult to break.

[0398] Furthermore, since the first linear material 12 and the second linear material 13 suppress the elongation of the strapping 10, the hole formed when fixed with the U-shaped nail 30 is difficult to expand. Therefore, it is possible to effectively prevent the strapping 10 from cracking through the hole formed when fixed with the U-shaped nail 30.

[0399] As described above, according to this embodiment, the intermediate layer 11 is provided, a first surface layer 16 covering one surface of the intermediate layer 11, and a second surface layer 17 covering the other surface of the intermediate layer 11, that is, a structure in which the first surface layer 16 and the second surface layer 17 are sandwiched between the intermediate layer 11. Furthermore, the intermediate layer 11 has a plurality of first linear materials 12 arranged side-by-side at an angle to the longitudinal direction D1 of the binding tape 10. With this structure, the strength of the binding tape 10 is increased due to the first linear materials 12, so even when U-shaped nails 30 are driven into the binding tape 10 for binding, it is difficult to break. Therefore, if the binding tape 10 is used, even for traction operations involving crops with high repulsive forces, the binding machine 20 can be used for binding operations.

[0400] Furthermore, the intermediate layer 11 has a second linear material 13 that intersects with the first linear material 12. This second linear material 13 suppresses the expansion of the spacing of the first linear material 12, thus suppressing the elongation of the strapping tape 10. Consequently, even after the strapping tape 10 is pulled following the insertion of the U-shaped nails 30 for binding, the holes pierced by the U-shaped nails 30 are difficult to expand, thus providing a strapping tape 10 that is difficult to tear.

[0401] It should be noted that in the above embodiments, the first surface layer 16 and the second surface layer 17 are formed from weather-resistant materials, but this is not a limitation; at least one of the first surface layer 16 and the second surface layer 17 may also be formed from photodegradable or biodegradable materials. In this configuration, the initial binding... Figure 11 (a) shows that the surface layer is not degraded, thus ensuring the binding strength. On the other hand, when the binding tape 10 is left in the field for a certain period of time, such as Figure 11 As shown in (b), the surface layer naturally deteriorates. When the surface layer deteriorates and only the intermediate layer 11 remains, the gaps between the first linear material 12 and the second linear material 13 constituting the intermediate layer 11 easily open, and the U-shaped nails 30 easily detach from the binding tape 10. Therefore, the binding tape 10 can be easily removed during crop harvesting. Moreover, even if the detached binding tape 10 falls onto the field, it is difficult to notice since only the fibers of the intermediate layer 11 remain. Furthermore, by setting the color of the first linear material 12 or the second linear material 13 to black or brown, it becomes a camouflage color when the fibers of the intermediate layer 11 fall onto the field or farmland, thus making it even less noticeable.

[0402] Furthermore, in the above embodiment, the intermediate layer 11 is composed of a first linear material 12 and a second linear material 13, but it is not limited to this; the intermediate layer 11 may also be composed solely of the first linear material 12. In this case, the first linear material 12 is preferably as follows: Figure 12 (a) shows an inclined configuration relative to the length direction D1 and width direction D2 of the strapping tape 10. It should be noted that... Figure 12 In (a), the first linear material 12 is exposed, but this is for illustrative purposes. That is, the actual front and back surfaces of the first linear material 12 (intermediate layer 11) are covered by the first surface layer 16 and the second surface layer 17 and are not exposed.

[0403] When the first linear material 12 is arranged at such an angle, as... Figure 12As shown in (b), the binding tape 10 can be extended within a certain range along the length direction D1. That is, it is possible to provide a binding tape 10 that has increased strength and moderate elasticity compared to the past. Such a binding tape 10 can be used, for example, in crop cultivation where the binding tape 10 needs to be extended to correspond to the growth of branches, i.e., where it is desirable to avoid excessive restriction and thus not hinder the growth of the tree.

[0404] Furthermore, the binding tape 10 can be composed of an intermediate layer 11 and a first surface layer 16 disposed on one surface of the intermediate layer 11. In this case, the second surface layer 17 may not be disposed on the other surface of the intermediate layer 11, thus exposing the other surface of the intermediate layer 11. Even in such a structure, the intermediate layer 11 has a plurality of first linear materials 12 at an angle relative to the longitudinal direction D1 of the binding tape 10. With such a structure, the strength of the binding tape 10 is increased due to the first linear materials 12, so it is difficult to break even when U-shaped nails 30 are driven into the binding tape 10 for binding. Therefore, if the binding tape 10 is used, even the traction operation of crops with high repulsive forces can be carried out using the binding machine 20.

[0405] It should be noted that the first surface layer 16 may not completely cover one surface of the intermediate layer 11. For example, one surface of the intermediate layer 11 may be exposed at one or both ends of the width direction D2 of the intermediate layer 11.

[0406] [Variation Example 1]

[0407] Hereinafter, a modified example of the binding strap 10 of the first embodiment, the binding strap 10A, will be described using the accompanying drawings. It should be noted that elements that can be used in the same or identical structure or function as those described in the first embodiment, as would be understood by those skilled in the art, are omitted or simplified in their description.

[0408] Figure 14 This is a perspective view of the strapping tape 10A. As shown in the figure, the strapping tape 10A is wound around the core 19. A first slit 14A1 is formed on one side 10A1 of the wound strapping tape 10A, that is, at one end or edge of the strapping tape 10A in the width direction D2. As shown in the figure, twelve first slits 14A1 are formed on the side 10A1, extending radially from approximately the center of the core 19, for example, with rotational symmetry of 30 degrees. The slits may also be slits.

[0409] A second slit 14A2 is formed on the other side 10A2 of the same winding binding tape 10A, that is, at the other end or edge of the binding tape 10A in the width direction D2. Twelve second slits 14A2 are formed on the side 10A2, extending radially from approximately the center of the core 19, for example, with rotational symmetry of 30 degrees.

[0410] As shown in the figure, the first cut 14A1 and the second cut 14A2 are formed at different positions along the length direction D1 of the strapping tape 10A. Specifically, the second cut 14A2 is formed at a position along the length direction D1 between two adjacent first cuts 14A1 formed separately along the length direction D1 of the strapping tape 10A. Furthermore, the first cut 14A1 is formed at a position along the length direction D1 between two adjacent second cuts 14A2 formed separately along the length direction D1 of the strapping tape 10A.

[0411] Figure 15A This is a perspective view schematically illustrating that the strapping tape 10A is composed of an intermediate layer 11A, a first surface layer 16 covering one surface of the intermediate layer 11A, and a second surface layer 17 covering the other surface of the intermediate layer 11A. The lengths of the first surface layer 16, the intermediate layer 11, and the second surface layer 17 in the width direction D2 are approximately the same. However, the lengths of the first surface layer 16 and the second surface layer 17 in the width direction D2 may be greater than the length of the intermediate layer 11 in the width direction D2. On the other hand, the lengths of the first surface layer 16 and the second surface layer 17 in the width direction D2 may be smaller than the length of the intermediate layer 11 in the width direction D2. In this case, the surface at the end of the intermediate layer 11 in the width direction D2 is exposed and not covered by the first surface layer 16 and the second surface layer 17.

[0412] exist Figure 15A A first cut 14A1 is formed at one end of the intermediate layer 11A in the width direction D2. A second cut 14A2 is formed at the other end of the intermediate layer 11A in the width direction D2. Moreover, the first cut 14A1 and the second cut 14A2 are formed at different positions in the length direction D1.

[0413] It can also replace Figure 15A The binding tape 10A shown is as follows: Figure 15B The binding strap 10 of the first embodiment is modified in the manner shown in the binding strap 10B.

[0414] like Figure 15BAs shown, the strapping tape 10B is composed of an intermediate layer 11A, a first surface layer 16B covering one surface of the intermediate layer 11A, and a second surface layer 17B covering the other surface of the intermediate layer 11A. A first cut 14B1 is formed at one end of the intermediate layer 11B in the width direction D2. Furthermore, a cut 16B1 is formed in the first surface layer 16B at a position corresponding to the first cut 14B1, and a cut 17B1 is formed in the second surface layer 17B at a position corresponding to the first cut 14B1. Furthermore, a cut 16B2 is formed in the first surface layer 16B at a position corresponding to the second cut 14B2, and a cut 17B2 is formed in the second surface layer 17B at a position corresponding to the second cut 14B2. However, it is also possible that neither the first surface layer 16B nor the second surface layer 17B has any cuts formed.

[0415] For example, strapping tape 10A and strapping tape 10B can be mounted on... Figure 4 and Figure 5 The strapping machine 20 shown is used to strap the object to be strapped.

[0416] Figure 16A and Figure 16B This is a schematic perspective view showing the strapping tape 10B mounted on the strapping machine 20, with U-shaped nails 30 driven in to secure the object (not shown). It should be noted that the U-shaped nails 30 have a... Figure 6 The structure shown is the same as the one described above. Specifically, it includes a crown 32 extending in a first direction, a first leg 31 connected to the crown 32 at one end in the first direction and extending in a second direction intersecting the first direction, and a second leg 31 connected to the crown 32 at the other end in the first direction and extending in a third direction intersecting the first direction (but may also be the same as the second direction). One end of each leg 31 may be a free end. Figure 6 The U-shaped nail 30 shown has rounded corners. It can also be represented as a rectangular U-shape.

[0417] When inserting U-shaped nails 30 into the 10B binding tape, as Figure 16A As shown, the legs 31 of the U-shaped nail 30 pass through the overlapping binding tapes 10B respectively. Then, as... Figure 16BAs shown, the legs 31 of the U-shaped nail 30 are twisted and bent inward. Thus, the overlapping binding tape 10B is held in place by the legs 31 and crown 32 of the U-shaped nail 30. At this time, at least one bundle of first thread material 12 and second thread material 13 is sandwiched between the legs 31 and crown 32. Furthermore, a first slit 14A1 is formed on one side of the binding tape 10B in the width direction D2, and a second slit 14A2 is formed on the other side. Therefore, as shown in the figure, a first slit 14A1 is formed at one end of the loop of the binding tape 10B formed by fastening with the U-shaped nail 30 in the width direction D2, and a second slit 14A2 is formed at the other end of the loop in the width direction D2.

[0418] In this state, even if the strapping tape 10B is pulled, the legs 31 of the U-shaped nail 30 will engage with at least one of the first linear material 12 and the second linear material 13, thus inhibiting the movement of the U-shaped nail 30. Therefore, since the through hole formed by the U-shaped nail 30 penetrating the strapping tape 10B is difficult to expand, the possibility of the strapping tape 10 cracking can be prevented.

[0419] The technical significance of the first incision 14A1 or the second incision 14A2 is explained below.

[0420] As described above, a cutting blade (not shown) for cutting the strapping tape 10B after strapping is provided at the front end 21a of the main handle 21 of the strapping machine 20. After forming the loop of tape to be strapped 40, the U-shaped nail 30 is driven out by the U-shaped nail driving tool. After the strapping tape 10B is attached, the cutting blade provided at the front end 21a of the main handle 21 is used to cut the attached loop of tape.

[0421] The inventors of this application discovered a situation where the second linear material 13 located at the end of the width direction D2 among a plurality of second linear materials 13 arranged side by side along the width direction D2 was not cut. For example, when the cutting blade used to cut the strapping tape 10B is formed by a plurality of blades formed periodically, like a saw blade, the inventors of this application discovered that insufficient force was not applied from the blade to the second linear material 13 located outside the width direction D2 of the blade at the end of the width direction D2. As a result, the second linear material 13 at the end of the width direction D2 sometimes could not be cut. The second linear material 13 is connected to the strapping tape 10B mounted on the strapping machine 20, so normally the user of the strapping machine 20 would have to cut the second linear material 13 that could not be cut.

[0422] However, multiple first cuts 14B1 are formed at the end of the width direction D2 of the intermediate layer 11B of the strapping tape 10B. Therefore, at least a portion of the second linear material 13 disposed at one end in the width direction D2 is pre-cut by the first cuts 14B1. Thus, it is normally easy to cut the second linear material 13 that was not cut by the cutting blade of the strapping machine 20. It should be noted that the second linear material 13 disposed at one end in the width direction D2 may not be completely cut by the first cuts 14B1. For example, at least a portion of the second linear material 13 disposed at one end in the width direction D2 is cut by the first cuts 14B1, thereby allowing for easier cutting compared to the conventional method, through pulling based on the cutting action of the strapping machine 20 or by gently pulling by hand. Preferably, at least 60% or more of the length of at least one second linear material 13 in the width direction D2 is cut by the first cuts 14B1.

[0423] It should be noted that when a single second linear material 13 is formed by bundling multiple fiber raw materials (e.g., multiple polyester fibers), it is preferable that more than half of the length (e.g., 0.5 mm) of the second linear material 13 in the width direction D2 is cut by the first cut 14B1. More preferably, more than 60% of the length of the second linear material 13 in the width direction D2 is cut by the first cut 14B1. However, if there is unevenness on the side of the wound binding tape 10B, the depth of the slit formed by pressing the knife against the side of the binding tape 10B to become the first cut 14B1 may also be uneven. However, if the length of the first cut 14B1 in the width direction D2 is increased, the binding tape 10B elongates along the length direction D1, which may sometimes hinder the cutting of the binding tape 10B. Therefore, the length of at least one first cut 14B1 in the width direction D1 relative to the width of the binding tape 10B is preferably 15% or less.

[0424] Similarly, at least a portion of the second linear material 13 disposed at the other end of the width direction D2 is pre-cut by the second cut 14B2. Therefore, the second linear material 13 disposed at the other end of the width direction D2 can also be easily cut.

[0425] As described above, since multiple slits are provided at one end of the middle layer of the strapping tape in the width direction, separating along the length direction of the strapping tape, the adverse effects caused by the failure to cut the second linear material can be reduced.

[0426] It should be noted that the binding tape does not necessarily need to have both a first cut and a second cut. For example, the first cut may only be formed on one end of the binding tape in the width direction.

[0427] Furthermore, when multiple slits are provided at both ends of the middle layer of the strapping tape along its length, the longitudinal positions of the slits at one end and the slits at the other end are preferably asymmetrical with respect to a line passing through the center of the strapping tape's width. This configuration helps to suppress a decrease in the tensile strength of the strapping tape.

[0428] Furthermore, the number, shape, and length of the slits can be appropriately varied. In this modified example, the slits appear radial when viewed from the side. However, this is not limited to this modified example. For example, slits can also be formed on the side of a binding strap that appears as a grid pattern when viewed from the side.

[0429] [Second Implementation]

[0430] Figure 17A This is a perspective view of the wound body 110 of the second embodiment, viewed from the left side. Furthermore, Figure 17B , Figure 17C and Figure 17D These are, respectively, a cross-sectional view of the coiled body 110 including the central axis AX, a perspective view viewed from the right side, and a magnified view of a portion near the central axis AX. However, Figure 17A This shows the situation where the binding strap 112 is pulled out slightly and the outer periphery of the binding strap 112 spreads out.

[0431] As shown in the accompanying drawings, the wrapped body 110 includes: a cylindrical tube member 120; a strapping tape 112 wound around the outer peripheral surface of the tube member 120; a membrane 114 (an example of a "first member") disposed opposite to one of the side surfaces 112C and 112D of the wrapped strapping tape 112; and an adhesive layer 116 disposed between the membrane 114 and the side surface 112D for bonding the membrane 114 and the side surface 112D.

[0432] The tube member 120 is formed as a hollow cylinder centered on the central axis AX, and has the following features: at least a portion of which contains a radius D2 centered on the central axis AX. Figure 17D The cylindrical surface 120B serves as an example of an inner wall; the outer peripheral surface 120A comprises at least a portion of a cylindrical surface with a radius larger than the radius D2 centered on the central axis AX; the inner wall surface 120B and the outer peripheral surface 120A are connected by an end face 120D facing the direction of the central axis AX and an end face 120C facing the opposite direction to the end face 120D. The tube member 120 is a core for winding the binding tape 112, and may be, for example, a paper tube formed into a tubular shape from thick paper, or a plastic such as resin.

[0433] The binding tape 112 is, for example, a tape used to bind two or more items together. To prevent the tape from sticking firmly to the items and hindering binding when hand-tying, the inner circumferential surface 112B (facing inwards) is used during winding. Figure 17A The outer peripheral surface 112A, which faces outward and is opposite to the inner peripheral surface 112B during winding, is not adhered. For example, the outer peripheral surface 112A and the inner peripheral surface 112B are made of a non-adhesive material without adhesive coating, thereby enabling the formation of such a binding tape 112.

[0434] The strapping tape 112 has a surface that forms one of the outer peripheral surfaces 112A, a surface that forms the other of the inner peripheral surfaces 112B, and a side surface that connects these surfaces to each other. The strapping tape 112 has a side surface 112D facing the direction of the central axis AX when wound around the outer peripheral surface 120A of the tube member 120 with the central axis AX as the winding axis, and a side surface 112C facing in the opposite direction to the side surface 112D. In this embodiment, the width of the strapping tape 112 is approximately the same as the length of the tube member 120 in the direction of the central axis AX. Therefore, when the strapping tape 112 is wound, the end face 120D of the tube member 120 and the side surface 112D of the strapping tape 112 exist on the same plane that are approximately flush, and the end face 120C and the side surface 112C exist on the same plane that are approximately flush.

[0435] The membrane 114 is a generally circular membrane body whose surface faces the end face 120D of the tube member 120 and the side face 112D of the strapping strap 112 and is arranged in a manner that is generally concentric with the central axis AX. A circular hole H1, which is generally concentric with the central axis AX, is formed in the center of the membrane 114. Therefore, the hole H1 communicates with the region S surrounded by the inner wall surface 120B of the tube member 120. The membrane 114 can be made of, for example, paper or other fibers or plastic. Moreover, it can also be a structure in which they are stacked. It should be noted that the part that communicates with the region S surrounded by the inner wall surface 120B of the tube member 120 is not limited to the circular hole H1 formed in the membrane 114. For example, the membrane 114 can also be formed in a generally C-shape, and the communicating part can be formed in the shape of a cut with an opening. When the film 114 is made of a material that is water-resistant and elastic, such as resin or rubber, or synthetic paper made by mixing resin with pulp, it can be used appropriately even when the rolled-up body 110 is exposed to wind and rain in an environment such as outdoor use.

[0436] like Figure 17B As shown, the radius of the membrane 114 is formed to be larger than the radius of the wound binding tape 112 in its unused state. Furthermore, as... Figure 17DAs shown, the radius D1 of the hole H1 is smaller than the radius D2 of the inner wall surface 120B. Therefore, in the cross-section including the central axis AX, the radius D2, which is the minimum distance between the central axis AX and the inner wall surface 120B, is larger than the radius D1, which is the minimum distance between the central axis AX and the membrane 114. Moreover, information related to the tape winding 110 is printed on the surface 114A on the other side of the membrane 114. Figure 17C ).

[0437] like Figure 17D As shown, the surface of the membrane 114 is bonded to the opposite side surface 112D of the strapping tape 112 via an adhesive layer 116. In this embodiment, the adhesive layer 116 is composed of an adhesive layer laminated on the surface of the membrane 114. Therefore, the surface of the membrane 114 is bonded to approximately the entire surface of the side surface 112D of the strapping tape 112 and approximately the entire surface of the end face 120D of the tube member 120. It should be noted that the adhesive layer 116 may also be provided by applying or spraying adhesive onto the side surface 112D of the strapping tape 112.

[0438] The dimensions of each component of the winding body 110 described above can be appropriately designed according to the application. For example, the length of the tube component 120 in the central axis AX direction can be set to 5 to 15 mm, the diameter of the inner wall surface 120B can be set to 10 to 30 mm, and the diameter of the outer peripheral surface 120A can be set to 15 to 40 mm. Furthermore, the width of the binding tape 112 can be set to 5 to 15 mm, the thickness to 0.05 to 0.4 mm, and the length to 10 to 40 m, so that it can be configured to have an outer diameter of, for example, 100 to 120 mm during winding. Moreover, the thickness of the film 114 can be set to 0.5 to 3 mm, the outer diameter to 100 to 130 mm, the inner diameter to 10 to 20 mm, and the amount of protrusion from the inner wall surface 120B, i.e., the difference between the radius D2 and the radius D1, can be set to 1 to 5 mm.

[0439] Figure 18 This illustrates the usage of the wrapping material 110 when the bundled object is tied by hand. For example... Figure 18 As shown, the strapping tape 112 is pulled out by supporting the tape winding body 110 with branches WD or pillars, etc., through the region S surrounded by the inner wall surface 120B of the tube member 120 and the hole H1. At this time, the side 112D of the strapping tape 112 is bonded to the membrane 114, which is the membrane body, through the adhesive layer 116. Therefore, even if the strapping tape 112 rotates when pulled out, the strapping tape 112 can be prevented from unraveling due to inertial force. Similarly, unraveling during the handling of the strapping tape 112 can also be prevented. Moreover, even when storing the strapping tape 112 after use, it is difficult for it to unravel because the side 112D of the outer peripheral end of the strapping tape 112 is bonded to the membrane 114.

[0440] Furthermore, the surface bonded to the film 114 is not the outer peripheral surface 112A and inner peripheral surface 112B of the strapping tape 112, but rather the side surface 112D, whose area per unit length is extremely small compared to these outer peripheral surfaces 112A, etc. Therefore, unraveling can be prevented and the strapping tape 112 can be easily pulled out. Moreover, by printing information related to the tape roll 110 on the surface 114A of the film 114, it is possible to distinguish the tape roll 110 from other tape rolls even after it has been removed from the box. It should be noted that the printed information is not limited to tape roll identification information. Information can also be displayed on the surface 114A of the film 114 by methods other than printing. However, displaying information is not mandatory and may be optional.

[0441] It should be noted that even assuming the outer periphery of the strapping tape 112 has come apart after use, a portion of the outer periphery 112A or the inner periphery 112B can be stored in a state of being bonded and fixed to the surface of the film 114 exposed due to the use and reduction of the strapping tape 112.

[0442] Furthermore, the membrane can be various shapes, not just circular, such as rectangular or polygonal. Moreover, it doesn't have to be adhered to the entire side of the strapping tape; it can be adhered only to a portion of the side. However, by forming the membrane in a larger manner, such as by adhering it to the side of the outermost strapping tape, the necessity of securing the outer periphery of the strapping tape with tape or similar material can be eliminated. Therefore, the labor and time required to remove work gloves and peel off the outer periphery of the tape whenever the strapping tape is changed can be saved. For example, by making the membrane rectangular and adhering it to the side of the outermost strapping tape near its vertices, efficient use of the membrane can be achieved. On the other hand, the outer diameter of the membrane can also be formed to be smaller than the outer periphery of the strapping tape at the beginning of its use. Figure 17E An embodiment is shown in which the outer diameter of the membrane 114 is formed as a circle smaller than the outer peripheral surface 112A of the strapping tape 112 at the beginning of use.

[0443] Furthermore, the membrane does not need to be fully bonded to the end face of the pipe member; it can be bonded only to a portion or not at all. For example, the end face of the pipe member can be separated from the membrane by making the length of the pipe member along its central axis smaller than the width of the strapping tape, thus creating a gap. However, by bonding the membrane to the end face of the pipe member as well, the membrane can be stably supported even when the bonding area between the side of the strapping tape and the membrane is reduced due to the use of strapping tape.

[0444] Furthermore, the membrane pores do not necessarily have to be formed in a way that the membrane protrudes from the inner wall of the tube member towards the central axis; they can also be formed as circular or polygonal pores larger than the inner wall of the tube member. However, by forming small pores in a way that the membrane protrudes from the inner wall of the tube member, the membrane pores can be seen through the area surrounded by the inner wall of the tube member when bonding the membrane to the side of the strapping tape. Therefore, when manufacturing the tape roll 110 by bonding the membrane to the side of the strapping tape wound around the tube member, the alignment of the membrane becomes easier. Moreover, even if a positional deviation occurs when bonding the membrane to the side of the strapping tape, a portion of the membrane can still be bonded to the end face of the tube member. For example, when the inner diameter of the membrane pores is set to ±0.3 mm, the inner diameter of the tube member is set to ±0.3 mm, and the positioning crossover when bonding the membrane to the side of the strapping tape is set to ±0.3 mm, a maximum error of 0.9 mm is generated. Therefore, by making the radius of the membrane's pores at least 1 mm smaller than the radius of the inner wall of the tube member, the end face of the tube member can be reliably bonded to a portion of the membrane even if positional deviation occurs. The membrane can also be bonded concentrically to the side of the strapping tape, but it doesn't have to be concentric. Furthermore, the pores formed in the membrane, as described above, don't necessarily have to be circular. For example, they can be polygonal shapes such as rectangles or hexagons, or they can be slits or cuts. Moreover, for example, they can be rotationally symmetric shapes like stars, with varying distances from the center.

[0445] Furthermore, the membrane may not have pores. For example, the membrane may be constructed as a circular or polygonal shape without pores. Even in a coiled body constructed with such a structure, when used, a hole can be formed by puncturing the membrane, allowing a mandrel or similar device to penetrate the central portion of the membrane.

[0446] Alternatively, a slit can be formed in the center of the membrane. Even with a winding structure like this, when used, the membrane can be pressed open using the slit to create a hole that can penetrate the center of the membrane using a mandrel or similar material.

[0447] Furthermore, the outer peripheral surface 120A of the pipe member 120 may also be formed as a surface that is not cylindrical. Moreover, the inner wall surface 120B may not be a cylindrical surface; for example, it may also have irregularities formed on its surface.

[0448] Furthermore, the thickness (T) of the membrane along the central axis AX is preferably set to, for example, 0.05 mm or more and 2 mm or less. By setting the membrane thickness (T) to 0.05 mm or more and 2 mm or less, it is easy to conform to the irregularities and adhere to the membrane even when the sides of the wound binding tape have irregularities. Moreover, when the tape rolls are stacked, the increase in height can be suppressed.

[0449] In addition to forming the adhesive layer on the membrane surface, a double-sided tape separate from the membrane can also be used. Furthermore, an isotropic adhesive can be applied or sprayed onto the membrane and bonded to the side of the strapping tape. Alternatively, the adhesive can be applied or sprayed onto the side of the tape or the end face of the tubular component.

[0450] The above describes one example of a membrane as a membrane body, but any component with a certain thickness can be used to replace a membrane.

[0451] [Variation Example 2]

[0452] Hereinafter, a modified example of membrane 114 will be described. Other structures are the same as in the second embodiment, so the same or similar reference numerals are used and the description is omitted or simplified.

[0453] Figure 19 A modified example of membrane 114 is shown in membrane 124 (an example of the "first component"). On the surface of membrane 124 opposite to the side of the strapping tape 112, there are six regions 124B1 with an adhesive layer 116 and six regions 124B2 without adhesive. As shown, the six regions 124B2 are formed with 60-degree rotational symmetry about the center C1 of membrane 124. The circumferential distance between two adjacent regions 124B2 decreases from the outer periphery towards the inner periphery of membrane 124. For example, the circumferential distance between adjacent regions 124B2 near the outer periphery is represented by distance D3, the circumferential distance between adjacent regions 124B2 near the inner periphery is represented by distance D4 (smaller than distance D3), and the circumferential distance between adjacent regions 124B2 near the inner periphery is represented by distance D5 (smaller than distance D4). The bonding area between the side 112D of the strapping tape 112 and the membrane 124 is the sum of the circumferential distances between adjacent regions 124B2 at a position separated from the center C1 by a specified distance, integrated over the distance from the center C1. Therefore, Figure 19 The bonding area between the side 112D of the strapping tape 112 and the membrane 124 decreases from the outer peripheral side to the inner peripheral side in an area of ​​more than half the radius of the membrane 124.

[0454] The following uses Figure 20A and Figure 20B This explains the effect of such a membrane 124. It should be noted that in this modified example, a pipe member with a larger diameter than the pipe member 120 shown in the second embodiment is used, but since it has the same function, the same reference numerals are used.

[0455] Figure 20A This shows the situation where the strapping tape 112 is pulled out while most of it is still attached. Figure 20BThe diagram shows the situation where the strapping tape 112 is pulled out with most of it used and a small amount remaining.

[0456] There is a high residual amount of 112 in the binding tape. Figure 20A In the case shown, the distance D10 between the central axis AX of the strapping tape 112 and the position where it is pulled out is large. Therefore, even if the strapping tape 112 is pulled with the same force, a large torque will be generated.

[0457] On the other hand, the residual amount of the 112 strapping tape is low. Figure 20B In the case shown, the distance D11 between the central axis AX of the strapping tape 112 and the winding position is smaller than the distance D10. Therefore, even when pulling the strapping tape 112 with the same force, only a smaller torque is generated. In other words, the pulling resistance of the strapping tape 112 increases. Therefore, the strapping tape 112 cannot be pulled out as intended. Moreover, if excessive force is applied, the strapping tape 112 may sometimes be over-pulled out.

[0458] By bonding the membrane 124 shown in this modified example to the side surface 112D of the strapping tape 112, the bonding area of ​​the strapping tape 112 to the side surface 112D can be reduced from the outer peripheral side to the inner peripheral side. Therefore, compared with the case where the membrane 114 is used, the increase in pull-out resistance on the inner peripheral side can be mitigated.

[0459] It should be noted that the area 124B2 without adhesive coating can also form a hole as a through membrane 124. Moreover, the shape of the area 124B2 can be any shape that reduces the bonding area with the side of the strapping tape from the outer periphery to the inner periphery, and various shapes such as circles and polygons can be used.

[0460] [Variation Example 3]

[0461] The following describes a modified example of the coiled body 110, namely the coiled body 130. The same or similar reference numerals are used for the same constituent elements, and their descriptions are omitted or simplified.

[0462] The tape roll 130 differs from the tape roll 110 of the second embodiment in that it uses two films 134 (an example of a “first component”) and 136 (an example of a “second component”) instead of film 114.

[0463] Figure 21A This is a left-side view of the coiled body 130. Figure 21BThis is a cross-sectional view of the wound body 130 through the central axis AX. The membrane 134 is a generally circular membrane body, having an adhesive layer 116B on one surface coated with an adhesive (not shown). A portion of the surface 134B of the membrane 134 opposite the side 112D of the strapping tape 112 is bonded to the side 112D of the strapping tape 112 opposite to the surface 134B using the adhesive layer 116B, and another portion is bonded to the surface 136 of the membrane 136 opposite to the surface 134B using the adhesive layer 116C. Furthermore, as... Figure 21B As shown, a circular hole H2 with a diameter smaller than the inner diameter of the tube member 120 is formed at the center of the membrane 134. It should be noted that in this modified example, the outer diameter of the membrane 134 is formed to be slightly smaller than the outer diameter of the binding tape 112 in the wound state.

[0464] A membrane 136 is sandwiched between the membrane 134 and the side 112D of the strapping 112. In this modified example, the membrane 136 is a generally circular membrane body, with a generally circular hole H3 formed in the central portion including the center. Figure 21B The outer diameter of membrane 136 is formed to be larger than the outer diameter of tube member 120, while the inner diameter is formed to be approximately the same as the inner diameter of membrane 134. Therefore, as Figure 21B As shown, in the cross-section passing through the central axis AX, holes H2 and H3 communicate with the region S surrounded by the inner wall surface 120B of the tube member 120. Furthermore, the inner diameter ends of membrane 134 and membrane 136 protrude from the inner wall surface 120B of the tube member 120. Membrane 136 is a membrane formed from fibers such as paper or resin such as plastic. In this modified example, an adhesive is applied to the surface opposite to membrane 134, but no adhesive is applied to the surfaces opposite to the side surface 112D of the strapping tape 112 and the end face 120D of the tube member 120. Therefore, membrane 136 is bonded to membrane 134, but not to the strapping tape 112 or the tube member 120. It should be noted that the portion communicating with the region S surrounded by the inner wall surface 20B of the tube member 120 is not limited to holes H2 formed in membrane 134 or holes H3 formed in membrane 136.

[0465] For example, membrane 134 or membrane 136 can be formed into a roughly C-shape, with the connected portions forming a cut shape with openings. When membrane 134 or membrane 136 is made from water-resistant and stretchable materials such as resin or rubber, or synthetic paper made by mixing resin and pulp, it can be used appropriately even in environments where the roll 110 is exposed to wind and rain, such as outdoor use.

[0466] Figure 21CThis is a cross-sectional view showing a process for manufacturing such a tape-wound body 130. As shown in the figure, a jig 150 formed by connecting cylinders of different diameters can be used to manufacture the tape-wound body 130. Specifically, a cylindrical portion 150B with an outer diameter D51 and a cylindrical portion 150A with an outer diameter D50 smaller than the outer diameter D51 at the front end of the cylindrical portion 150B are formed concentrically as the jig 150. The outer diameter D51 is approximately equal to the inner diameter of the tube member 120, so the cylindrical portion 150B can hold the tube member 120 with the binding tape 112 wound on it. The outer diameter D50 is approximately equal to the inner diameters of the membranes 134 and 136, so the cylindrical portion 150A can hold the membranes 134 and 136. With the tubular member 120, on which the strapping tape 112 is wound, held by the cylindrical portion 150B, the cylindrical portion 150A holds the membrane 136 through the hole H3, thereby allowing the membrane 136 to be concentrically arranged side by side on the side surface 112D of the strapping tape 112. Next, the cylindrical portion 150A holds the membrane 134 through the hole H2, and presses the surface 134B of the membrane 134 against the surface of the membrane 136 and the side surface 112D of the strapping tape 112.

[0467] Through the above process, membrane 134, membrane 136, tube component 120, and the strapping tape 112 wound around tube component 120 can be concentrically integrated. When the strapping tape 112 is made of resin, it may expand or shrink depending on the temperature, or it may elongate under the stress during winding. Therefore, compared with the case where the position is aligned based on the outer diameter of the strapping tape 112, the accuracy of the position alignment can be improved.

[0468] It should be noted that, in order to prevent the pipe component 120 from moving towards... Figure 21A The paper can move to the left, and a large-diameter cylindrical portion that contacts the end face 120C of the tube member 120 can also be provided in the clamp 150. Moreover, the tape winding body 110 and other tape winding bodies with a film as a single sheet can also be positioned and integrated in the same way so that the film and the tube member are concentric.

[0469] According to this tape winding 130, the bonding area between the film 134 and the side surface 112D of the strapping tape 112 can be adjusted by adjusting the outer diameter of the film 136. Therefore, when the residual amount of strapping tape 112 decreases, the bonding area between the film 134 and the strapping tape 112 can be reduced, or the bonding can be eliminated, thereby reducing the pull-out load of the strapping tape 112. Moreover, the film 136 can suppress the exposure of adhesive on the surface of the film 134. Furthermore, the film 136 can cover the adhesive residue from the surface of the film 134. Figure 21A The area of ​​the pipe component 120 protruding towards the center can be seen when viewed from the left side, thus suppressing the accumulation of dust and other contaminants in that area.

[0470] It should be noted that the membrane 136 can also be formed without any adhesive coating on any surface. In this case, region 124B2 can also be provided on the outer periphery. Figure 19 In this case, the membrane 136 has a shape in which a generally circular central portion with a hole formed in the center is connected to the outer periphery of the central portion and an extension portion is provided in a manner that the area decreases as it extends towards the outer diameter. Moreover, a non-contact surface may be provided by applying a release agent or the like to a region on the surface of the membrane 134 opposite to the membrane 136, without providing the membrane 136.

[0471] In the aforementioned tape winding body, since a membrane is provided that adheres to the side of the strapping tape, the unraveling of the strapping tape can be suppressed. The effect of protruding the membrane from the tube member will be explained below.

[0472] Figure 22A This is a schematic diagram showing the usage configuration in which the tape winding 140 is supported by the round bar B1. It should be noted that components that perform the same functions as in the second embodiment are indicated by the same symbols and their descriptions are omitted or simplified, even if the dimensions differ. Figure 22A This is a cross-sectional view of the coiled body 140 through the central axis AX. For simplicity, the portion of the membrane 114 protruding from the inner wall surface 120B toward the central axis AX is referred to as rib 114F. The rib 114F of the coiled body 140 is formed in a ring shape. In the cross-sectional view through the central axis AX, the amount of protrusion of the rib 114F from the inner wall surface 120B is represented by the protrusion amount P. Furthermore, the width of the tube member 120 in the direction of the central axis AX is represented by the width W2.

[0473] As shown in the figure, by providing rib 114F, the tape winding 140 is supported by the round bar B1 at two points at both ends in the direction of the central axis AX when supported by the round bar B1. Specifically, it contacts the round bar B1 at the front end of the membrane 114 exposed to the hole H1 and at the position 114F1 where the distance from the central axis AX is minimized, and at the other end 120F on the inner wall surface 120B of the tube member 120, which is on the opposite side of the membrane 114 in the direction of the central axis AX. By providing such two support points, the rib 114F is not required, therefore, compared to the case where the contact point with the round bar B1 is not fixed, the tape winding 140 can be stably supported. In particular, because Figure 22A The lower side of the binding strap 112 has a large torque acting on the membrane 114 at position 114F1, thus improving stability.

[0474] It should be noted that when the width W2 is 5 to 15 mm, the protrusion P is preferably 1 mm or more, that is, 6.6% or more of the width W2. In this case, in the cross-section including the central axis AX, the connection T1 (which is connected to the membrane 14 at one end in the direction of the central axis AX and to the pipe member 120 at the other end in the direction of the central axis AX) Figure 22A The angle θ between the connector T1 and the central axis AX is 3.8 degrees or more. It should be noted that when the inner wall surface 20B of the pipe member 120 is arranged parallel to the central axis AX in this cross-section, the angle θ1 between the connector T1 and the inner wall surface 20B is the same as angle θ. If the protrusion P is smaller than this, it may be difficult to make positions 114F1 and 20F contact as support points when the surface of the round bar B1 has an unevenness of about 1 mm or an inclination of about 3 degrees. For example, when the width W2 is 15 mm and the protrusion P is 0.8 mm, the angle θ becomes approximately 3 degrees.

[0475] Furthermore, when the width W2 is 5 to 15 mm, the protrusion P is preferably 7.5 mm or less, that is, less than 50% of the width W2. In this case, the angle θ becomes 26.5 degrees or less. When the protrusion P increases, a large load acts on the position 120F side, and depending on the situation, the membrane 114 may fall over due to the weight of the strapping 112 causing the membrane 114 to rotate in the opposite direction of clockwise in the attached drawing.

[0476] It should be noted that the rib 114F does not have to be annular. For example, it can also be a structure in which a cut is made in the rib 114F and multiple protrusions protruding toward the central axis AX are arranged separately in the circumferential direction.

[0477] It should be noted that, in the case where the membrane 114, as an example of the first component, is flexible and can be elastically deformed, and the rib 114F is configured to be flexible, and the protrusion P of the rib 114F from the inner wall surface 120B is 1 mm or more, and the thickness (T) of the rib 114F in the central axis AX direction is 0.05 mm or more and 2 mm or less, if the tape winding body 140 is supported by the round bar B1, then as Figure 22B As shown, the rib 114F flexes and deforms in the insertion direction of the round rod B1. Through the flexing of the rib 114F, a backflow prevention effect is achieved, making it difficult for the round rod B1 to be pulled out, and the coiled body 140 is difficult to fall off from the round rod B1.

[0478] in addition, Figure 22CThe case shown is where the shape of the round rod B2 is more than twice the radius D1 of the hole H1 of the membrane 114. Even in this case, if the membrane 114, as an example of the first component, is flexible and can be elastically deformed, and the rib 114F is flexible, the protrusion P of the rib 114F from the inner wall surface 120B is more than 1 mm, and the thickness (T) of the rib 114F is more than 0.05 mm and less than 2 mm, if the tape winding 140 is supported by the round rod B2, the rib 114F will flex and deform in the insertion direction of the round rod B2. Through the flexing of the rib 114F, a check-back effect can be achieved, making it difficult for the round rod B2 to be pulled out, and the tape winding 140 is difficult to fall off the round rod B2.

[0479] [Third Implementation Method]

[0480] The third embodiment describes a form in which the tape roll is loaded into a tying machine. Using the tying machine, branches or vines of fruit trees or vegetables can be tied to supports, or vegetables can be tied together or bags can be tied together.

[0481] Figure 23 This is a front view of a strapping machine 200. The strapping machine 200, a handheld tool, includes a clamping arm 210, a strapping machine body 240, a handle 212, a tape pull-out section 220, a tape conveyor section 242, a U-shaped staple box section 260, and a tape box section 280. Tape rolls are loaded into the tape box section 280. Furthermore, the end of the strapping tape of the tape roll is held in a state where it is pulled out from the tape guide 246 of the tape conveyor section 242 towards the upper side in the figure.

[0482] When the user grips the handle 212 and approaches the strapping machine body 240, the clamping arm 210 approaches the strapping machine body 240 according to the lever principle, and the strapping tape is clamped by the tape catcher 224 and tape plate 226 of the tape pull-out section 220. When the user loosens their grip on the handle 212, the clamping arm 210 separates from the strapping machine body 240 while the strapping tape is being clamped, and the strapping tape is pulled upward from the tape guide 246. In this state, if multiple items to be bundled, such as vegetable branches and supports, are present in the space between the clamping arm 210 and the tape conveyor 242, and the user presses the strapping machine 200 to the right of the paper surface, the items to be bundled come into contact with the strapping tape, and the strapping tape is further pulled out from the tape guide 246. Furthermore, when the user grips the handle 212 again, the clamping arm 210 approaches the strapping machine body 240 again, and the strapping tape is wrapped around the items to be bundled. Furthermore, as the clamping arm 210 descends, the tape guide 246 moves along the opposite inclined surface of the tape catcher 224. When it reaches a position where movement is restricted, the tape catcher 224 rotates in the direction of separation from the tape plate 226 (front side). Simultaneously, the tape guide 246 also rotates forward. With the rotation of the tape guide 246, a cutting blade located at its front end cuts the strapping tape. Furthermore, U-shaped studs loaded in the U-shaped stud box body 262 are ejected, securing the overlapping portions of the strapping tape. Through this series of processes, the object to be strapped is secured.

[0483] For proper use in such a strapping machine 200, the tape roll needs to be kept rotatable within the tape holder 280. When using a tape roll consisting only of a tubular member and the strapping tape wound around that member, a shaft penetrating the area surrounded by the inner wall of the tubular member is provided in the tape holder 280, thereby allowing the tape roll to be kept rotatable. However, when holding a tape roll with a large inner diameter tubular member, the increased gap with the shaft makes it difficult to stably keep the tape roll rotatable.

[0484] The inventors of this application conceived of a method that allows the tape winding 110 to be stably kept in a rotatable state by using the tape winding 110.

[0485] Figures 24A to 24CThis is a schematic diagram illustrating a method for holding the tape winding 110. The tape box portion 280 includes a shaft portion 282 having a central axis AX2. The shaft portion 282 includes: a cylindrical portion 282A formed in a cylindrical shape; and a frustum-shaped portion 282B formed at the front end of the cylindrical portion 282A. The radius of the bottom surface of the frustum-shaped portion 282B is larger than the radius of the cylindrical portion 282A. Therefore, the shaft portion 282 includes: an annular bottom portion 282A1 protruding from the cylindrical portion 282A; and an inclined surface 282A2 as a conical surface. Here, the radius D20 of the cylindrical portion 282A is formed to be approximately the same diameter as the radius D1 of the hole H1. Moreover, the radius D22 of the frustum-shaped portion 282B is smaller than the radius D2 of the inner wall surface 120B of the tube member 120 and larger than the radius D1 of the hole H1.

[0486] This shaft portion 282 is configured to move along the central axis AX2 within the housing portion 280 and to rotate about the central axis AX2. For example, the shaft portion 282 can be configured to be oriented by a helical spring (not shown) towards... Figure 24A The device is held within the belt housing 280 under a downward force applied in the direction of the central axis AX2, and can be manually moved upward in the direction of the central axis AX2 by pressing the bottom surface 282D. Furthermore, it can be configured to rotate around the central axis AX2 via a bearing (not shown).

[0487] Figures 24A to 24C It is a cross-sectional view of the tape winding 110 mounted in the tape box 280 and the shaft portion 282 of the tape box 280, cut along a plane including the central axis AX2 of the shaft portion 282. Figure 24A The diagram shows the state before the tape roll 110 is installed. The central axis AX of the tape roll 110 does not need to be aligned with the central axis AX2 of the shaft portion 282. However, it is preferable to place the tape roll 110 in the tape cassette portion 280 such that the central axis AX and the central axis AX2 are close to each other and approximately parallel, with a distance smaller than the protrusion of the film 114.

[0488] Next, as Figure 24B As shown, the shaft portion 282 is moved upward in the direction of the central axis AX2. The radius D22 of the frustum-shaped portion 282B is formed to be larger than the radius D1 of the hole H1, so the inclined surface 282A2 contacts the end of the membrane 114. However, the end of the membrane 114 is a free end, so as shown in the figure, it can deform in conformation to the inclined surface 282A2. Furthermore, when the shaft portion 282 is moved upward, the bottom surface 182A1 of the frustum-shaped portion 282B passes through the membrane 114. Therefore, the frustum-shaped portion 282B is housed in the area surrounded by the membrane 14 and the inner wall surface 120B of the tube member 120.

[0489] Then, when the shaft portion 282 is stopped from being pressed upwards in the direction of the central axis AX2, the shaft portion 282 moves under the force of the coil spring. However, the bottom part 282A1 of the truncated cone portion 282B contacts the edge of the membrane 114 and the hole H1, thus acting as a limiting member. Therefore, as Figure 24C As shown, the truncated cone portion 282B can retain the coiled body 110 while still being housed within the area surrounded by the membrane 114 and the inner wall surface 120B of the tube member 120. At this time, the end of the membrane 114 deforms downward in the direction of separation from the tube member 120, i.e., in the direction of the central axis AX2.

[0490] As described above, a tape roll can be provided that allows for stable holding using a strapping machine by forming holes with the membrane protruding towards the central axis AX. Furthermore, even tape rolls with different inner diameters of tubular components can be held in place by making the holes approximately the same diameter.

[0491] It should be noted that the hole H1 does not necessarily have to be circular. For example, the hole H1 can be formed with two short sides existing on the side surface 112D of the binding tape 112, and two long sides transversely cutting over the area S surrounded by the end face 120D of the tube member 120 and the inner wall surface 120B of the tube member 120. Even with such a structure, since a portion of the membrane 114 protrudes beyond the inner wall surface 120B of the tube member 120, the shaft portion 282 can still be used to hold the tape winding.

[0492] Alternatively, the shaft portion 282 need not be configured to be rotatable. Even when the shaft portion 282 is not rotating, the tape winding 110 can still be rotated because the shaft portion 282 slides on the surface of the film 114.

[0493] [Variation Example 4]

[0494] As the second embodiment of the strapping tape 112, or as the strapping tape shown in other embodiments, modifications, etc., a strapping tape having the same structure as the strapping tape 10 or its modifications may also be used.

[0495] In this case, the strapping material has a cylindrical tube member, a strap with the same structure as the strapping tape 10, which is wound around the tube member and can bind the object being bound, and a first member located on the side of the wound tape, the first member being bonded to at least a portion of the side of the tape. As described above, the first member may, for example, be configured to be flexible and elastically deformable. Furthermore, the strapping tape wound around the tube member has an intermediate layer and a first surface layer covering one surface of the intermediate layer. The intermediate layer has a plurality of first linear materials arranged side-by-side at an angle relative to the length direction of the strapping tape.

[0496] Such a spool has an intermediate layer and a first surface layer covering one side of the intermediate layer. Furthermore, the intermediate layer has a plurality of first linear materials arranged side-by-side at an angle to the length of the spool. Therefore, the spool is difficult to tear. If such a spool is used, even for traction operations involving crops with high repulsive forces, spooling operations can be performed using a horticultural spooling machine.

[0497] [Variation Example 5]

[0498] As the binding strap 112 in the second embodiment, or as the binding strap shown in other embodiments, modifications, etc., a binding strap equipped with the same... Figure 14 This is a strapping tape with the same structure as the strapping tape 10A shown. In this case, a plurality of first slits separated along the length direction of the strapping tape are formed at one end of the intermediate layer in the width direction. Furthermore, a plurality of second slits separated along the length direction of the strapping tape may also be formed at the other end of the intermediate layer in the width direction. Moreover, at least one first slit may also cut off at least a portion of the second linear material.

[0499] [Variation Example 6]

[0500] Hereinafter, a modified example of membrane 114 will be described. Other structures are the same as in the second embodiment, so the same or similar reference numerals are used and the description is omitted or simplified.

[0501] Figure 25 A modified example of membrane 114 is shown in membrane 134 (an example of the "first component"). On the surface of membrane 134 opposite to the side of the strapping tape 112, there is a region 134B1 where an adhesive layer 116 is formed by coating with an adhesive such as an acrylic adhesive and the like, and a region 134B2 where no adhesive is coated.

[0502] Figures 26A to 26C It is Figure 25 The diagram shown illustrates the division of region 134B1 into an outer peripheral region 134B11, a middle region 134B12, and an inner peripheral region 134B13.

[0503] As shown in the accompanying figures, the peripheral region 134B11 is formed in the region 134B1 containing the adhesive layer 116, and is located on the outer periphery of the membrane 134, most separated from the center C2 of the membrane 134. By providing the peripheral region 134B11 and adhering at least a portion thereof to the side of the wound strapping 112, warping of the membrane 134 can be suppressed. Such a peripheral region does not necessarily need to be formed over the entire circumference of the outer edge or periphery; for example, it may be formed only covering a portion of the outer edge. The width of the peripheral region 134B11 is determined based on the material of the strapping 112, its surface condition, the adhesive strength of the coating, the bonding strength, the compression load during sealing, etc.

[0504] The inner peripheral region 134B13 is formed in the region 134B1, which includes the adhesive layer 116, and is close to the inner edge or inner periphery of the membrane 134. However, as shown in the figure, in this modified example, an uncoated adhesive region 134B2 is formed in the region including the inner edge or inner periphery. At least a portion of the inner peripheral region 134B13 is adhered to the region on the outer diameter side of the end face 120D of the tube member 120, thereby preventing the membrane 134 from separating from the strapping tape 112 even if its lateral area is reduced due to the use of the strapping tape 112. Moreover, in the event of disposal, the labor and time required to pick up the tube member such as the paper tube that has separated from the membrane are reduced, and the membrane 134 and the tube member 120 can be disposed of together. The uncoated adhesive region 134B2 surrounded by the inner peripheral region 134B13 may also be unnecessary. However, when the inner circumference of the membrane 134 is smaller than that of the inner circumference of the tube member 120 and the membrane 134 protrudes from the inner wall surface of the tube member 120, by forming a region such as region 134B2 where no adhesive is applied, it is possible to suppress the adhesion of waste, the adhesion and accumulation of adhesive to the assembly part when assembled with the strapping machine.

[0505] The inner peripheral region is preferred in Figure 25 As shown in the top-down view, it forms around the center C2 on the entire circumference.

[0506] The intermediate region 134B12 is formed in a spiral shape that extends circumferentially from the center C2 outwards, connecting the outer periphery of the inner peripheral region 134B13 to the inner periphery of the outer peripheral region 134B11. The intermediate region 134B12 is connected to the outer periphery of the inner peripheral region 134B13 and the inner periphery of the outer peripheral region 134B11. Therefore, an imaginary circle centered on the center C2, larger than the inner peripheral region 134B13 and smaller than the outer peripheral region 134B11, regardless of its diameter, will necessarily pass through the adhesive-coated region 134B1 and the uncoated region 134B2. Therefore, a portion of the circumference of the strapping tape 112 can theoretically adhere to the adhesive-coated region 134B1. Thus, the uncoiling of the strapping tape 112 can be suppressed. However, this does not preclude the possibility that the circumference of the strapping tape 112 may not be bonded to the area 134B1 due to uneven sides. Moreover, it can prevent situations where excessive adhesive adheres to the strapping tape 112, thus hindering the binding of the object, can be suppressed.

[0507] In this modified example, the intermediate region 134B12 is formed such that the arc length passing through the coated region 134B1 in an imaginary circle that is larger than the inner peripheral region 134B13 and smaller than the outer peripheral region 134B11 is less than the arc length passing through the uncoated region 134B2. Therefore, it is possible to suppress the excessive increase in pull-out resistance of the strapping 112.

[0508] Furthermore, in this modified example, the intermediate region 134B12 is formed such that the larger the diameter of the imaginary circle, which is larger than the inner peripheral region 134B13 and smaller than the outer peripheral region 134B11, the greater the ratio of the arc length through the uncoated region 134B2 to the arc length through the coated region 134B1. Therefore, it is possible to suppress the increase in pull-out resistance that occurs as the distance from the center C2 decreases with the use of the strapping 112.

[0509] Alternatively, the intermediate region 134B12 can be formed as follows: Figure 25 As shown in the top view, the line segment connecting the outer peripheral region 134B11 and the inner peripheral region 134B13 along the straight line passing through the center C2 includes the area where the adhesive is applied, namely the middle region 134B12, regardless of the angle. With this structure, the film 134 and the strapping tape 112 can be bonded in all directions, thus allowing the strapping machine to stably hold the film 134. Furthermore, it can prevent the strapping tape 112 from unraveling.

[0510] It should be noted that the intermediate region 134B12 is preferably formed in one-third of the region from the inner periphery to the outer periphery of the membrane 134, and more preferably in one-half of the region. Furthermore, the inner periphery region 134B13, the outer periphery region 134B11, and the intermediate region 134B12 can also be separated from each other. Moreover, the intermediate region 134B12 can also be formed from multiple separated regions. For example, the intermediate region 134B12 can also be formed from multiple separated circles.

[0511] It should be noted that, in this modified example, the inner peripheral region 134B13 is an example of the first part of the first member. The outer peripheral region 134B11 and the middle region 134B12 are examples of the second part of the first member. Furthermore, the region 134B2, which is not coated with adhesive, is an example of the non-adhesive part of the first member.

[0512] Furthermore, the intermediate region 134B12 includes an example of a first arc portion. The region 134B2, which is not coated with adhesive, is an example of a second arc portion. The intermediate region 134B12 includes multiple first arc portions because the arc on the imaginary circle containing the first portion is included within multiple imaginary circles of different diameters. Moreover, the region 134B2, which is not coated with adhesive, includes multiple second arc portions because the arc on the imaginary circle containing the first portion is included within multiple imaginary circles of different diameters.

[0513] Figure 27 This is a top view of membrane 144 (an example of the "first component"), a modified example of membrane 114. On the surface of membrane 144 opposite to the side of the strapping tape 112, there is a region 144B1 where an adhesive layer 116 is formed by applying an adhesive or the like, and a region 144B2 where no adhesive or the like is applied.

[0514] As shown in the figure, the outer perimeter region 144B11 of region 144B1 is formed in the same way as the outer perimeter region 134B11, and the inner perimeter region 144B13 is formed in the same way as the inner perimeter region 134B13. Therefore, detailed explanation is omitted.

[0515] The intermediate region 144B12 is formed such that it extends from the center C3 in the outward radial direction and along the circumferential direction, connecting the outer periphery of the inner peripheral region 144B13 with the inner periphery of the outer peripheral region 144B11. Furthermore, the intermediate region 144B12 is composed of seven separate small regions that are rotationally symmetrical with respect to the center C3.

[0516] In this structure, an imaginary circle centered on center C3, larger than the inner peripheral region 144B13 and smaller than the outer peripheral region 144B11, regardless of its diameter, will necessarily pass through the adhesive-coated region 144B1 and the uncoated region 144B2. Therefore, the uncoating of the strapping 112 can be suppressed.

[0517] Furthermore, the intermediate region 144B12 is formed such that the arc length of the imaginary circle passing through the coated region 144B1 is less than the arc length passing through the uncoated region 144B2 within the imaginary circle that is larger than the inner circumferential region 144B13 and smaller than the outer circumferential region 144B11. Therefore, it is possible to suppress the excessive pull-out resistance of the strapping tape 112. Preferably, 60% to 70% of the circumference of the imaginary circle passes through the uncoated region 144B2, and 30% to 40% passes through the intermediate region 144B12 coated with adhesive, etc.

[0518] Furthermore, in this modified example, the larger the diameter of the imaginary circle that is larger than the inner circumferential region 144B13 and smaller than the outer circumferential region 144B11, the greater the arc length passing through the coated region 144B1. Therefore, as the use of the binding tape 112 progresses, the increase in pull-out resistance that accompanies the decrease in distance from the center C3 can be suppressed.

[0519] It should be noted that, in this modified example, the intermediate region 144B12 is an example of multiple portions that are bonded to the side of the strapping tape of the first member. Furthermore, the region 144B2, which is not coated with adhesive, is an example of a non-bonded portion of the first member.

[0520] [Fourth Implementation Method]

[0521] Figure 28A This is a perspective view of the roll 310 according to the fourth embodiment. Figure 28B It is a sectional view of the roll 310 after being cut with a plane including the axis AX.

[0522] As shown in the accompanying drawings, the spool 310 includes a cylindrical tube member 312 and a protrusion 314 extending from one end face of the tube member 312 toward the axis AX of the tube member 312. In this embodiment, the tube member 312 and the protrusion 314 are integrally formed.

[0523] The outer peripheral surface 312A of the tube member 312 is formed as a cylindrical surface with a radius R1 centered on the axis AX. Furthermore, the inner wall surface 312B of the tube member 312 is formed as a cylindrical surface with a radius R2 centered on the axis AX. An end face 312C connecting the outer peripheral surface 312A and the inner wall surface 312B is formed at one end along the axis AX. A protrusion 314 is formed at the other end along the axis AX. The space S is a hollow space surrounded by the inner wall surface 312B of the tube member 312. The tube member 312 is a core for winding and binding the strapping tape 420; for example, it can be a paper tube formed of paper such as thick paper, or it can be formed of plastic such as resin.

[0524] The protrusion 314 extends toward the axis AX of the pipe member 312 from one end face side. The protrusion 314 is annular, having an outer peripheral portion 314A with a radius R1 centered on the axis AX, an inner peripheral portion 314B with a radius R3 centered on the axis AX, an end face 314C facing the pipe member 312, and an end face 314D facing the axis AX in the opposite direction to the end face 312C. The outer peripheral portion 314A is flush with the outer peripheral surface 312A of the pipe member 312. On the other hand, the radius R3 of the inner peripheral portion 314B is smaller than the radius R2 of the inner wall surface 312B of the pipe member 312. Therefore, the protrusion 314 has a rib 314E protruding from the inner wall surface 312B of the pipe member 312 toward the axis AX. The amount of protrusion of the rib 314E from the inner wall surface 312B is represented by the difference between the radius R2 and the radius R3. As shown in the figure, in this embodiment, the rib 314E is formed in a ring shape centered on the axis AX. Furthermore, a circular hole H1, which is surrounded by the rib 314E and communicates with the space S, is formed in the central part through which the axis AX passes.

[0525] Figure 29A This is a perspective view of a roll 400 with a binding tape 420 wound on it, viewed from the end face 314D of the protrusion 314. It should be noted that, hereinafter, the roll with the binding tape wound on will be referred to as roll 400, roll 400A, etc., while the roll without the binding tape wound on will be referred to as roll 310, roll 310A, etc., to distinguish between the two.

[0526] Figure 29B It is a sectional view of the roll 400 cut with a plane including the axis AX. Figure 29C It is Figure 29B A magnified view of a portion of the rib near 314E. It should be noted that... Figure 29A Although the dimensions of the rib 314E are formed in accordance with the dimensions of the 310 shown, the 310 is formed in accordance with the dimensions of the rib 314E. Figure 28A The roll 310 shown may differ from others, but since they have the same function, they are labeled with the same number, and their descriptions are omitted. The same applies to other drawings; even if the components differ in size, elements with the same function are labeled with the same number, and their descriptions are omitted.

[0527] The binding tape 420 is wound around the outer peripheral surface 312A of the pipe member 312 with its surface 420B facing the axis AX and its opposite surface 420A facing the outer diameter direction. The result of winding the binding tape 420 is the formation of a side surface 420C facing the axis AX and a side surface 420D facing the opposite axis AX. Figure 29BAs shown, in this embodiment, the length of the axial direction of the roll 310 is approximately the same as the width of the strapping tape 420, so the side surface 420C is approximately flush with the end surface 312C. Similarly, the side surface 420D is approximately flush with the end surface 314D of the protrusion 314.

[0528] The dimensions of each component of the aforementioned roll 400 can be appropriately designed according to the application. For example, the length of the tube member 312 in the axial direction (AX) can be set to 5–15 mm, the radius R2 of the inner wall surface 312B to 5–15 mm, and the radius of the outer peripheral surface 312A to 7.5–20 mm. Furthermore, the width of the binding tape 420 can be set to 5–15 mm, the thickness to 0.05–0.4 mm, and the length to 10–40 m, allowing it to be configured to have a radius of, for example, 50–60 mm during winding. The thickness of the protrusion 314 in the axial direction (AX) can be set to, for example, 1 mm or less. Moreover, the difference between the radius R2 and the radius R3 of the rib 314E protruding from the inner wall surface 312B toward the axial direction (AX) can be set to, for example, 1 mm or more. Furthermore, the protrusion 314 preferably has flexibility.

[0529] Figure 30 This illustrates the use of the roll 400 when the bundled items are tied by hand. (Example) Figure 30 As shown, the drum 400 is supported by a branch WO or a support, which serves as a core rod, penetrating the area S and the hole H1 surrounded by the inner wall surface 312B of the tube member 312, thereby enabling the drum 400 to rotate about the axis AX and pull out the strapping 420.

[0530] Figure 31A and Figure 31B This is a schematic diagram illustrating the usage configuration of the drum 400 when it is supported by a cylindrical mandrel B1 in a manner that penetrates the region S and the hole H1 surrounded by the inner wall surface 312B of the tube member 312. Figure 31A This is a cross-sectional view taken along a plane containing the axis AX, during the intermediate movement of the drum 400 relative to the mandrel B1 in the rightward direction relative to the mandrel B1, so that the mandrel B1 passes through the region S and the hole H1. Figure 31B It is a sectional view of the mandrel B1 supporting the drum 400, which passes through region S and hole H1, using a plane including the axis AX.

[0531] like Figure 31AAs shown, when the radius R4 of the mandrel B1 is greater than the radius R3 of the inner circumference 314B, the mandrel B1 contacts the front end of the rib 314E. Furthermore, even when the radius R4 of the mandrel B1 is equal to or less than the radius R3 of the inner circumference 314B, the mandrel B1 may still contact the front end of the rib 314E when moving relative to the mandrel B1 in a manner that prevents the axis of the mandrel B1 from being concentric with the axis AX. However, since the front end of the rib 314E is a free end, it can deform as shown in the figure. Therefore, the mandrel B1 can penetrate region S and hole H1. With the mandrel B1 penetrating region S and hole H1, supporting the drum 400, as shown... Figure 31B As shown, the tube member 312 tilts due to the weight of the strapping tape 420 and the tube member 312 itself. Therefore, in the cross-section after cutting with a plane including the axis AX, the connecting wire T1 (which passes through the region S and the hole H1 and connects to the drum 310 at both ends in the direction of the axis AX) Figure 31B The drum 400 is inclined relative to the axis AX. Specifically, the connector T1 is connected to the drum 310 at two points: the front end 314E1 of the rib 314E and the end 312E of the inner wall surface 312B on the end face 312C side. The drum 400 can be supported on the mandrel B1 at two points separated along the axis AX, thus eliminating the need for the rib 314E. Therefore, compared to a case where the contact point with the mandrel B1 is not fixed, it can be stably supported. This is especially true because the drum 400 is inclined relative to the mandrel B1. Figure 31B The weight of the lower binding strap 420 creates a large torque from the front end point 314E1 toward the mandrel B1, thus preventing the drum 400 from moving along the axis of the mandrel B1. Furthermore, the slight bending of the rib 314E at its free end, pressing against the mandrel B1, also prevents the drum 400 from moving along the axis AX. The rib 314E bends toward the insertion direction of the mandrel B1, thus providing a backlash prevention effect that makes it difficult for the mandrel B1 to be pulled out, preventing the drum 400 from detaching from the mandrel B1.

[0532] It should be noted that when the width of the tube member 312 in the axial direction AX is 5 to 15 mm, the protrusion of the rib 314E is preferably 1 mm or more, i.e., 6.6% or more of the width. In this case, in the cross section including the axial direction AX, the angle θ between the terminal T1 and the straight line including the axial direction AX is 3.8 degrees or more. It should also be noted that when the inner wall surface 312B of the tube member 312 and the axial direction AX are arranged parallel to each other in this cross section, the angle θ1 between the terminal T1 and the inner wall surface 312B is the same as the angle θ. When the protrusion of the rib 314E is reduced, it can be difficult to support the tube member B1 when the surface of the mandrel B1 has an unevenness of about 1 mm or when the unevenness has an inclination of about 3 degrees, using a support point separated by two points along the axial direction AX becomes difficult. Furthermore, when the width of the tube member 312 in the axial direction AX is 5 to 15 mm, the protrusion of the rib 314E is preferably 50% or less of the width. In this case, the angle θ is 26.5 degrees or less. When the protrusion is large, depending on the circumstances, the roll 400 may fall over due to the weight of the strapping tape 420.

[0533] The direction of flexure of rib 314E varies depending on how the mandrel B1 is inserted. For example, when the mandrel B1 is inserted through the end face 312C, rib 314E is more likely to flex outwards. Even in this case, the drum 400 can still be stably supported. When rib 314E flexes outwards, it provides a check valve effect, making it difficult for the mandrel B1 to be pulled out from the end face 312C, and the drum 400 is less likely to detach from the mandrel B1.

[0534] As described above, the drum 310 according to this embodiment can be supported by mandrels of various diameters at two points: the rib 314E formed at one end in the axial direction AX and the tube member 312 formed at the other end. Therefore, the rib 314E does not need to be provided, and thus it can be stably supported compared to the case where the contact part with the mandrel is not fixed.

[0535] It should be noted that the radius R4 of the mandrel B1 is larger than that of the inner circumference 314B. Figure 28B With a radius R3, the entire circumference of the inner circumference 314B contacts the mandrel B1, thus providing more stable support for the drum 400. For this more stable support, it is preferable to set the protrusion of the rib 314E to 1 mm or more.

[0536] It should be noted that the outer peripheral surface 312A only needs to have a surface capable of being wrapped with strapping, and does not necessarily need to be a cylindrical surface. Furthermore, the inner wall surface 312B does not need to be a cylindrical surface; for example, it can also have irregularities formed on its surface. Therefore, the tube member 312 only needs to be formed into a cylindrical shape.

[0537] [Variation Example 7]

[0538] Figures 32A to 32D The variations of the reel 400 shown in the fourth embodiment are all cross-sectional views along the axis AX including the tube member 312. It should be noted that for components that perform the same function, even if the dimensions are different, the same reference numerals are used and repeated descriptions are omitted.

[0539] Figure 32A The first modified example of the spool 400A is shown. The spool 400A includes a tube member 312 and a membrane 354A (an example of the "first member") extending as a protrusion on one end face of the tube member 312 toward the axis AX side of the tube member 312.

[0540] The membrane 354A is formed into an annular shape with an inner circumference of radius R5 and an outer circumference of radius R6, and is arranged concentrically with the axis AX of the tube member 312. The inner circumference radius R5 of the membrane 354A is smaller than the inner circumference radius R2 of the tube member 312. Therefore, the inner circumference portion of the membrane 354A has a portion protruding from the inner wall surface 312B of the tube member 312 toward the axis AX. Moreover, the outer circumference radius R6 of the membrane 354A is larger than the outer circumference radius R1 of the tube member 312. Furthermore, the surface of the membrane 354A is bonded to the annular end face 312D of the tube member 312 and a portion of the side surface 420D of the strapping tape 420 using an adhesive layer mainly composed of adhesive.

[0541] Even with this type of roll 310A, because the membrane 354A has a portion protruding from the inner wall surface 312B of the tube member 312 toward the axis AX, it can be supported at an inclined position on mandrels of various diameters at both ends in the axis AX direction. Furthermore, the surface of the membrane 354A is also adhered to the side surface 420D of the strapping tape 420, thus preventing it from unraveling when the strapping tape 420 is pulled out. Moreover, the tube member 312 and the membrane 354A can be formed from different materials. For example, the membrane 354A can be formed using plastic, and the tube member 312 can be formed using paper, thereby allowing the protruding portion requiring durability to be constructed using plastic.

[0542] In addition, using Figure 33AThis explains the effect of applying adhesive to the surface 354A2 of the protruding rib 354A1 of the membrane 354A facing the tube member 312. When the mandrel B2 is inserted from the end face 312C side, the rib 354A1 of the membrane 354A flexes outward. Here, the surface 354A2 of the rib 354A1 facing the tube member 312 is opposite to the mandrel B2 due to the flexing. Therefore, the roll 400A can be stably supported. As the strapping tape 420 is pulled out and the tube member 312 rotates, the adhesive applied to the surface 354A2 of the rib 354A1 facing the space S side gradually wears off, thus supporting the roll 400A more stably. It should be noted that the adhesive can also be formed in layers on the membrane 354A, or it can be blown onto the surface 354A2 of the membrane 354A by a sprayer or the like.

[0543] Figure 32B The second modified example of the roll 400B is shown. Compared with the first modified example of the roll 400A, the membrane 354B (an example of the "first component") is formed in such a way that the entire side surface 420D of the strapping tape 420 is opposite to the outer periphery of the roll 420, and the outer periphery radius R7 is larger than the outer periphery radius R8 of the strapping tape 420.

[0544] Even in such a roll 400B, because of the ribs 354E protruding towards the axis AX, it can be supported at an inclined position on the mandrel at two points separated in the axis AX direction. Furthermore, the surface of the membrane 354B is also adhered to the entire side surface 420D of the strapping tape 420, thus preventing the strapping tape 420 from unraveling when pulled out. Moreover, when storing the roll 400B mid-use, the outer peripheral end of the strapping tape 420 can be adhered to and fixed to the exposed surface of the membrane 354B. It should be noted that the membrane 354B can also be formed as a rectangle or other polygon instead of a ring shape. However, the distance between the vertex of the polygon and the axis AX is preferably at least half of the radius R8, more preferably at least the radius R8.

[0545] Figure 32C The third modified example of the roll 400C is shown. It differs from the first modified example of the roll 400A in that two membranes 354C1 (an example of the "first component") and membrane 354C2 (an example of the "second component") protrude from the inner wall surface 312B of the tube component 312. Membrane 354C1 is an annular membrane body, with an adhesive (not shown) coated on one surface. A portion of the surface opposite to the side surface 420D of the strapping tape 420 is bonded to the side surface 420D of the strapping tape 420 using this adhesive, and another portion is bonded to the opposite surface of membrane 354C2. Furthermore, a circular hole H3 with a radius smaller than the radius of the inner wall surface 312B of the tube component 312 is formed at the center of membrane 354C1.

[0546] A membrane 354C2 is sandwiched between the membrane 354C1 and the side surface 420D of the strapping tape 420. In this modified example, the membrane 354C2 is a generally annular membrane body, and its outer diameter is formed to be larger than the outer diameter of the tube member 312. A generally circular hole H4 is formed in the center of the membrane 354C2 containing the center. The radius of the hole H4 of the membrane 354C2 is formed to be smaller than the radius of the inner wall surface 312B of the tube member 312, and is formed to be approximately the same radius as the radius of the hole H3 of the membrane 354C1. Therefore, in the cross section including the axis AX, the holes H3 and H4 communicate with the region S surrounded by the inner wall surface of the tube member 312. Moreover, the inner diameter end of the membrane 354C1 and the inner diameter end of the membrane 354C2 become protrusions protruding from the inner wall surface 312B of the tube member 312. It should be noted that the membrane 354C2 is formed of, for example, non-adhesive paper or plastic, and is bonded to the membrane 354C1 on which an adhesive is coated, but is not bonded to the strapping tape 420 and the tube component 312.

[0547] Even in such a roll 400C, mandrels of various diameters can be supported at the two separated points. Furthermore, since the adhesive of film 354C2 and film 354C1 is not exposed, even when used in applications such as high-speed winding and bundling tape 420, the roll 400C can rotate smoothly without the adhesive adhering to the mandrel. Moreover, by using film 354C2 as an expensive but rigid plastic and film 354C1 as a structure made of inexpensive paper coated with adhesive, the durability of the protrusions can be improved and the cost reduced.

[0548] Figure 32D The fourth modified example of the roll 400D is shown. It differs from the modified example of the roll 400C in that the membrane 354D1 (an example of the "first component") is formed in a ring shape facing the entire surface of the side 420D of the strapping tape 420. Even with this roll 400D, it can be supported at an inclined position on the mandrel at two points separated in the axial direction AX. Furthermore, the surface of the membrane 354D1 is also adhered to the outer periphery of the side 420D of the strapping tape 420, thus preventing the strapping tape 420 from unraveling when pulled out. It should be noted that at least one of the membrane 354D1 or the membrane 354D2 (an example of the "second component") can also be constructed of a polygon such as a rectangle. Other recurring effects are omitted from the description.

[0549] It should be noted that when a protrusion is formed by two or more layers of membrane, such as Figure 33BAs shown, adhesive can also be applied to the surface 354A2 of the membrane 354A facing the tube member 312 to bond it to the end face of the tube member 312, and different membranes 354A3 can be attached. In this configuration, the membrane 354A3, which is also prone to wear, is made of a highly durable material such as plastic, which can reinforce the protrusions. Moreover, the membrane 354A3 is disposed within the space S surrounded by the inner wall surface 312B of the tube member 312, thus reducing the dimension of the roll in the axial direction AX.

[0550] Figures 32E to 32G This is another diagram showing the form of the drum 400, both being sectional views along the axis AX including the tube member 312. It should be noted that components performing the same function are labeled with the same reference numerals even if their dimensions differ, omitting redundant descriptions.

[0551] Figure 32E This diagram shows a form of the roll in which the tube member 312 and the rib 314E are integrally formed, but the position of the rib 314E differs from the form described above. The length of the roll and the tube member 312 in the axial direction AX, i.e., the distance between end face 312C and end face 12D, is, for example, 15 mm.

[0552] In this sectional view, the centerline C is a straight line passing through the center position CP on the axis AX of the pipe member 312 and perpendicular to the axis AX. The thickness T is the maximum thickness of the rib 314E in the axis AX direction. The rib 314E is formed, for example, in a manner where its thickness in the axis AX direction is constant regardless of its distance from the axis AX. Region W is a region with the center position CP as the origin О, the direction towards the end face 312D as the positive direction, and the direction towards the end face 312C as the negative direction, and the axis AX as the axis. The thickness T is, for example, 2 mm. The protrusion P of the rib 314E from the inner wall surface 312B is, for example, 1 mm.

[0553] The center position of rib 314E in the axial direction AX is formed within a region of ±5.5 mm. In the case of rib 314E shown in the figure, its center position in the axial direction AX is formed in a region W of +5 mm, that is, a region W separated from the center position CP by 5 mm along the axial direction AX and towards the end face 312D. The thickness T of rib 314E is 2 mm, so the face of rib 314E facing the center position CP is separated from the center position CP by 4 mm (=W-(T / 2)). Moreover, the face of rib 314E facing the opposite side, i.e., the outer side, is separated from the end face 312D by 1.5 mm (=7.5-(W+T / 2)), and is formed at a position closer to the centerline C than the end face 312D. It should be noted that, for reference, the figure also shows the case where the center position in the axial direction AX is in a region W of -5 mm. For example, a rib can also be provided in this region.

[0554] With such a structure, when a rod-shaped member such as a tree branch is inserted into the tube member 312, the rib 314E, which is a protrusion, is appropriately flexed due to the engagement between the rod-shaped member and the tube member 312, and the drum is stably supported without excessive tilting.

[0555] In addition, in order to allow the rib 314E to flex appropriately, the thickness T is preferably set to 0.05 mm or more and 2 mm or less, and the protrusion P of the rib 314E protruding from the inner wall surface 312B is 1 mm or more.

[0556] By designing the structure in this way, when a rod-shaped component such as a tree branch is inserted into the tube component and the belt is pulled out, the protrusion flexes, and an appropriate braking force can be obtained.

[0557] It should be noted that at least some of these dimensions and structures (protrusion amount P, thickness T, and the case where the rib 314E, which serves as a protrusion, is formed in region W) can also be applied. Figure 28B Other reels shown in this disclosure, such as reel 310.

[0558] Figure 32F The diagram shows a structure in which the tube component and the protrusion are integrally formed, with the protrusion located at the end of the drum. The length of the drum in the axial direction AX, i.e., the distance between end face 312C and end face 314D, is, for example, 9 mm.

[0559] The center position of rib 314E in the axial direction AX is formed within a region of ±5.5mm. In the case of rib 314E shown in the figure, its center position in the axial direction AX is formed in a region W of +4mm, that is, a region W separated by 4mm from the center position CP along the axial direction AX and toward the end face 314D.

[0560] With such a structure, when a rod-shaped member such as a tree branch is inserted into the tube member 312, the rib 314E, which is a protrusion, is appropriately flexed due to the engagement between the rod-shaped member and the tube member 312, and the drum is stably supported without excessive tilting.

[0561] In addition, in order to allow the rib 314E to flex appropriately, the thickness T is preferably set to 0.05 mm or more and 2 mm or less, and the protrusion P of the rib 314E protruding from the inner wall surface 312B is 1 mm or more.

[0562] By designing the structure in this way, when a rod-shaped component such as a tree branch is inserted into the tube component and the belt is pulled out, the protrusion flexes, and an appropriate braking force can be obtained.

[0563] Figure 32GSimilar to the roll 400D in the fourth variation, the protrusion is formed by two layers of membrane 354C1 and membrane 354C2. The length of the tube member 312 in the axial direction AX, i.e., the distance between end face 312C and end face 312D, is, for example, 9 mm. Moreover, the thicknesses T1 and T2 of membrane 354C1 and membrane 354C2 in the axial direction are, for example, 0.5 mm each. Therefore, the thickness T in the axial direction of the protrusion formed by the two-layer structure of membrane 354C1 and membrane 354C2 is, for example, 1.0 mm.

[0564] The center position of rib 314E in the axial direction AX is formed within a region of ±5.5mm. In the case of rib 314E shown in the figure, its center position in the axial direction AX is formed in a region W of +5mm, that is, a region W separated by 5mm from the center position CP along the axial direction AX and toward the end face 314D.

[0565] With such a structure, when a rod-shaped member such as a tree branch is inserted into the tube member 312, the rib 314E, which is a protrusion, is appropriately flexed due to the engagement between the rod-shaped member and the tube member 312, and the drum is stably supported without excessive tilting.

[0566] In addition, in order to allow the rib 314E to flex appropriately, it is preferable that the thickness T is 0.05 mm or more and 2 mm or less, and the protrusion P of the rib 314E protruding from the inner wall surface 312B is 1 mm or more.

[0567] By designing the structure in this way, when a rod-shaped member such as a tree branch is inserted into the tube member and the belt is pulled out, the protrusion flexes, providing appropriate braking force. It should be noted that the shape of holes H1 and even H4 can be various shapes other than circles. For example, it can be a polygon such as a rectangle or hexagon, or a hole with a cut or slit. Furthermore, for example, it can also be a hole forming a rotationally symmetric shape with a star-shaped protrusion whose distance from the axis AX varies. Figure 34 A spool 370 is shown forming a hole H5 with a plurality of slits H5A. The plurality of slits H5A communicate with the central circular portion of the hole H5 and are provided to extend from the axis AX in the outward direction. Therefore, the spool 370 has a plurality of rotationally symmetrical protrusions 314F that protrude toward the axis AX and are formed circumferentially separated from each other.

[0568] Because a slit H5A is provided in such a drum 370, the mandrel can easily pass through. Furthermore, the front end of the protrusion 314F near the axis AX contacts the mandrel, thus supporting the drum 370 and the binding tape 420 wound on the drum 370. At this time, due to the slit H5A, the protrusion 314F can easily bend. As a result, the contact area with the mandrel is increased, thereby improving stability.

[0569] Furthermore, the membrane may not have pores. For example, the membrane may be constructed as a circular or polygonal membrane without pores. Even in a coiled body constructed with such a structure, pores that can penetrate the central part of the membrane can be formed by puncturing the membrane during use, using a mandrel or the like.

[0570] Alternatively, a slit can be formed in the center of the membrane. Even with a winding structure like this, during use, by widening the membrane using the slit, a hole can be formed that can penetrate the center of the membrane using a mandrel or similar device.

[0571] It should be noted that the membrane only needs to have a portion protruding towards the axis at one end in the axial direction, or it can be replaced by other components with thickness along the axial direction.

[0572] [Fifth Implementation Method]

[0573] The fifth embodiment describes a form in which the roll is loaded into a tying machine. Using the tying machine, branches or vines of fruit trees or vegetables can be tied to supports, or vegetables can be tied together or bags can be tied together.

[0574] Figure 35 This is a front view of a strapping machine 800. As a handheld tool, the strapping machine 800 includes a clamping arm 810, a strapping machine body 840, a handle 812, a tape pull-out section 820, a tape conveyor section 842, a U-shaped staple box section 860, and a tape box section 880. A spool is loaded into the tape box section 880. Furthermore, the end of the strapping tape on the spool is held in a state where it is pulled out from the tape guide 846 of the tape conveyor section 842 towards the upper side in the figure.

[0575] When the user grips the handle 812 and approaches the strapping machine body 840, the clamping arm 810 moves closer to the strapping machine body 840 according to the lever principle, and the strapping tape is clamped by the tape catcher 824 and tape plate 826 of the tape pull-out section 820. When the user loosens their grip on the handle 812, the clamping arm 810 separates from the strapping machine body 840 while the strapping tape is clamped, and the strapping tape is pulled upward from the tape guide 846. In this state, with multiple bundled items such as vegetable branches and supports existing in the space between the clamping arm 810 and the tape conveyor section 842, when the user presses the strapping machine 800 to the right of the paper surface, the bundled items come into contact with the strapping tape, thus further pulling the strapping tape out from the tape guide 846. Then, when the user grips the handle 812 again, the clamping arm 810 moves closer to the strapping machine body 840 again, and the strapping tape is wound onto the bundled items. Furthermore, as the clamping arm 810 descends, the strap guide 846 moves along the opposite inclined surface of the strap catcher 824. When it reaches a position where movement is restricted, the strap catcher 824 rotates away from the strap plate 826 (front side). Simultaneously, the strap guide 846 also rotates forward. With the rotation of the strap guide 846, a cutting blade located at its front end cuts the strapping tape. Furthermore, U-shaped studs loaded in the U-shaped stud box body 862 are ejected, securing the overlapping portions of the strapping tape. Through this series of processes, the items to be strapped are bound.

[0576] For proper use in such a strapping machine 800, the roll needs to be kept rotatable within the tape holder 880. When using a roll consisting only of a tubular member and strapping wound around that member, the roll can be kept rotatable by providing a shaft portion penetrating the area surrounded by the inner wall of the tubular member in the tape holder 880. However, when holding a roll with a large inner diameter of the tubular member, the gap between the shaft portion and the tube increases, making it difficult to stably keep the roll rotatable.

[0577] The inventors of this application conceived of a situation where the roll disclosed herein could be stably held in the strapping machine 800.

[0578] Figures 36A to 36C This is a schematic diagram illustrating a method for holding the roll 400B. It should be noted that the same method can be used to hold rolls that have other embodiments or modifications.

[0579] The housing portion 880 includes a shaft portion 882 having a central axis AX2. The shaft portion 882 includes a cylindrical portion 882A and a frustum-shaped portion 882B formed at the front end of the cylindrical portion 882A. The radius of the base of the frustum-shaped portion 882B is larger than the radius of the cylindrical portion 882A. Therefore, the shaft portion 882 has an annular base portion 882B1 protruding from the cylindrical portion 882A and an inclined surface 882B2 that is a conical surface. Here, the radius R20 of the cylindrical portion 882A is formed to be approximately the same diameter as the radius R3 of the hole H1. Furthermore, the radius R22 of the frustum-shaped portion 882B is smaller than the radius R2 of the inner wall surface 312B of the tube member 312, but larger than the radius R3 of the hole H1.

[0580] Such a shaft portion 882 is configured within the housing portion 880 to be movable along the central axis AX2 and to be rotatable about the central axis AX2. For example, the shaft portion 882 can be configured to be oriented by a helical spring (not shown) towards... Figure 36A The device is held in a downward direction along the central axis AX2 within the belt housing 880, and can be manually moved upward along the central axis AX2 by pressing the bottom surface 882D. Furthermore, it can be configured to rotate around the central axis AX2 via a bearing (not shown).

[0581] Figures 36A to 36C It is a cross-sectional view of the spool 400B mounted in the cassette section 880 and the shaft section 882 of the cassette section 880, cut along a plane including the central axis AX2 of the shaft section 882. Figure 36A The state before the drum 400B is installed is shown. The axis AX of the drum 400B does not necessarily need to be aligned with the central axis AX2 of the shaft portion 882. However, it is preferable that the drum 400B is positioned within the tape box portion 880 such that the axis AX and the central axis AX2 are close to each other and approximately parallel by a distance smaller than the protrusion of the rib 354E.

[0582] Next, as Figure 36B As shown, the shaft portion 882 is moved upward in the direction of the central axis AX2. The radius R22 of the frustum-shaped portion 882B is formed to be larger than the radius R3 of the hole H1, so the inclined surface 882A2 contacts the end of the rib 354E. However, the end of the rib 354E is a free end, so it can deform to conform to the inclined surface 882A2 as shown in the figure. When the shaft portion 882 is moved further upward, the bottom surface 882A1 of the frustum-shaped portion 882B passes through the rib 354E. Therefore, the frustum-shaped portion 882B is housed in the region S surrounded by the rib 354E and the inner wall surface 312B of the tube member 312.

[0583] Then, when the shaft 882 is stopped from being pressed upwards in the direction of the central axis AX2, the shaft 882 moves under the force of the coil spring. However, the bottom part 882A1 of the truncated cone part 882B contacts the edge of the rib 354E and the hole H1, thus acting as a limiting member. Therefore, as Figure 36C As shown, the drum 400B can be maintained while the truncated cone portion 882B is still housed within the area surrounded by the rib 354E and the inner wall surface 312B of the tube member 312. At this time, the end of the rib 354E deforms downward in the direction away from the tube member 312, i.e., in the direction of the central axis AX2.

[0584] As described above, by forming a hole with the rib 354E protruding towards the axis AX, a roll capable of stable holding using a strapping machine can be provided. Furthermore, even rolls with different inner diameters of tubular components can be held in place by making the holes approximately the same diameter. It should be noted that, as described above, a membrane body without such a hole can be used by piercing the center of the membrane body to create a hole during use. Moreover, a cut can be formed at the end, and during use, the membrane can be pressed open by the shaft portion 882 using the cut, thereby forming a hole penetrating the central portion of the membrane.

[0585] The above embodiments are illustrative of the present invention and are not intended to limit the present invention to these embodiments only. If the tube component 312, protrusion 314, rib 314E, membrane 354A, rib 354A1, membrane 354B, rib 354E, membrane 354C1, membrane 354C2, membrane 354D1, membrane 354D2, and protrusion 314F are constructed using materials that have water resistance and ductility, such as resin or rubber, or synthetic paper made by mixing resin materials with pulp materials, then it can be appropriately used even when used outdoors in environments where the rolls 310, rolls 310A-310D, rolls 370, rolls 400, and rolls 400A-400D are exposed to wind and rain.

[0586] Furthermore, various modifications can be made to this invention as long as they do not depart from its spirit. For example, within the scope of ordinary inventive ability of those skilled in the art, some of the constituent elements of a certain embodiment or modification can be added to other embodiments or modifications. Moreover, some of the constituent elements of a certain embodiment or modification can be substituted for corresponding constituent elements of other embodiments or modifications.

[0587] [Variation Example 8]

[0588] As the fourth embodiment of the strapping tape 420, or as the strapping tape shown in other embodiments, modifications, etc., a strapping tape having the same structure as the strapping tape 10 or its modifications may also be used.

[0589] In this case, the roll (hereinafter, sometimes referred to as "roll" or "bandage wrap") has a binding tape for binding the object being bound. The roll includes a tube member, a binding tape wound around the tube member, and a protrusion extending from one end face of the tube member toward its axis. In a cross-section including the axis, a connection point is formed at a first contact point at the front end of the protrusion and at a second contact point on the other end face of the tube member, which is inclined relative to a straight line including the axis. The angle of inclination is preferably 3 degrees or more. Furthermore, the binding tape wound around the tube member has an intermediate layer and a first surface layer covering one surface of the intermediate layer. The intermediate layer has a plurality of first linear materials arranged side-by-side at an angle relative to the length direction of the binding tape. With such a bandage wrap, the binding tape is less likely to break. If such a binding tape is used, even for induction work on crops with high repulsive forces, binding operations can be performed using a horticultural binding machine.

[0590] [Variation Example 9]

[0591] As the binding strap 420 of the fourth embodiment, or as the binding strap shown in other embodiments, modifications, etc., a binding strap equipped with the same... Figure 14 The binding tape 10A shown or its variants have the same construction. In this case, a plurality of first slits separated along the length direction of the binding tape are formed at one end of the middle layer of the binding tape in the width direction. Furthermore, a plurality of second slits separated along the length direction of the binding tape can also be formed at the other end of the middle layer of the binding tape in the width direction. Moreover, at least one first slit can also cut off at least a portion of the second linear material. With such a tape winding, the binding tape is less prone to tearing. If such a binding tape is used, even for traction operations on crops with high repulsive forces, binding operations can be performed using a horticultural binding machine.

[0592] [Variation Example 10]

[0593] The membrane 354A provided in the roll 400A, the membrane 354B provided in the roll 400B, or the membranes shown in other embodiments and modifications, as a variation of the fourth embodiment, may also be the membranes shown in the membranes 134, 144, or their modifications.

[0594] By using a roll with such a film and a wrapping body, it is possible to further suppress the unraveling of the strapping tape. Furthermore, the present invention can be modified in various ways without departing from its spirit. For example, within the scope of ordinary inventiveness of those skilled in the art, some of the constituent elements of one embodiment can be added to other embodiments. Moreover, some of the constituent elements of one embodiment can be replaced with corresponding constituent elements of other embodiments. For example, strapping tape 10A can be used as the strapping tape wound onto the wrapping body of modified example 10.
