[0002] Fiber bundle support bodies for brush spreading rollers and brush rollers made from these identical or similar fiber bundle support bodies

[0003] The invention relates to a device for guiding or widening webs of material during transport. Widening prevents creasing and thus avoids waste or reduced quality. To keep the material wide, lateral forces must be applied to the web; since this occurs when the web is moved, the lateral force, which acts outwards from the center of the web, is usually applied by rotating devices such as spreading rollers.

[0004] Well-known spreading rollers include, for example, so-called banana rollers, which are arc-shaped and whose arc generates the outward force. A disadvantage is that the arc shape creates varying tensions across the web width.

[0005] This disadvantage is not present in the cord spreader, where round cords are pulled outwards during contact with the web and thus spread outwards. This can lead to markings on films, but the technical effort is also a disadvantage, as these cord spreaders must be driven and synchronized.

[0006] A particularly simple spreading roller uses inclined fiber bundles which, upon contact with the web, easily deform outwards in the direction of the inclination and thus transmit a spreading force to the web, according to patent DE 10 2004 038 165 A1. Since the fiber bundles are inclined outwards towards the end of the roller, a V-shaped annular gap results in the middle of the roller, which can cause irritations on the web in the form of folds or creases, especially when the web is cut in the middle.

[0007] According to patent DE 102010053397 B4, the problem can be solved by installing fiber bundles with opposite inclination directions in the roller's central area, thereby neutralizing the spreading force, but this is only effective in one respect. Patent attorneys 2

[0008] Even though the brush spreading rollers are composed of individual fiber bundle support bodies, at least two different fiber bundle support body designs must be used per roller, since the solution for the roller center is designed differently than the remaining segments.

[0009] The problem at the center of the rollers lies in the fact that fiber bundles are installed there at a different angle than the standard spreader fiber bundles. This results in the diameter of the spreader roller remaining larger at its center due to the pressure of the overflowing web. Since the web is always pulled towards the largest diameter, this can lead to the formation of tension creases at the roller's center, a phenomenon that should be avoided at all costs.

[0010] Known solutions, such as different tilt angles or materials, increase storage costs and lead to increased design and programming effort and expenses. Additions like anti-rotation devices or special fiber bundle arrangements also mean additional costs and increased technical complexity.

[0011] Even with brush spreading rollers that use single-track brush strips, zones without fiber bundles are created in the center of the roller. This occurs because the diagonally arranged fiber bundles are directed outwards from the center of the roller, making a V-shaped area without fiber bundling unavoidable.

[0012] Task

[0013] The aim of the present invention is to solve the described difficulties through a simple, yet extremely flexible and cost-effective design. Patent Attorneys 3

[0014] This solution consists of several fiber bundle support bodies for each roller size, which are all identical in design and with which the following properties can be achieved simply and effectively:

[0015] • Only one fiber bundle support body for each roller diameter

[0016] • Elimination of the V-shaped annular gap

[0017] • All fiber bundles are aligned in the same direction (axially) and at the same inclination

[0018] • Spreading force from the center of the roller continuously to the end of the roller

[0019] • Highly flexible fiber bundle arrangements

[0020] • Various fiber bundle arrangements can be combined

[0021] • Effective anti-rotation device

[0022] • Easy assembly

[0023] • Low storage costs

[0024] Similar results can also be achieved with brush spreading rollers with brush strips if they are designed in such a way that defects in the fiber bundles in the center of the roller are avoided by suitable measures, which can also be achieved with simple solutions.

[0025] In other words, the invention relates to a support body for carrying spreading elements on a spreading roller. The invention further relates to a support shaft part for a spreading roller with a shaft central longitudinal axis. The invention further relates to a roller part for a spreading roller with a roller part central longitudinal axis. The invention also relates to a spreading roller, in particular a brush spreading roller, for laterally spreading a planar web of material in axial spreading directions with spreading elements which, upon contact with the web, exert a spreading force on the web, and with a rotational longitudinal axis. The invention relates to patent attorneys 4

[0026] Furthermore, a method for manufacturing a spreading roller. The invention also relates to the use of a tooth element of a spreading roller.

[0027] Devices for guiding and / or keeping webs of goods or material webs spread during the transport of such webs are known from the prior art, in particular so-called spreading rollers.

[0028] Spreading the web prevents wrinkling, thus avoiding reduced quality and consequently rejects and waste. To maintain spreadness, lateral forces acting perpendicular to the direction of travel must be applied to the web. Since these lateral forces are applied as the web moves, they are typically generated and applied laterally from the center of the web outwards using rotating devices, such as spreader rollers.

[0029] These types of spreading rollers exist in a wide variety of designs.

[0030] Well-known spreading rollers include, for example, so-called banana rollers, which are curved along their longitudinal axis. This "curve" generates outward-acting forces, more precisely, transverse forces acting perpendicular to the direction of travel of the web. Such banana rollers are suitable for most webs. However, a disadvantage is that the curved shape creates varying stresses across the web width.

[0031] This disadvantage is not present in another type of spreader roller, the so-called cord spreader, in which round cords are pulled outwards during contact with the web, thus spreading the web. However, the use of round cords can lead to markings on films. Furthermore, the technical effort involved is also a disadvantage, as these cord spreaders not only require special drives and synchronization. Patent Attorneys 5

[0032] Furthermore, patent application DE 10 2004 038 165 A1 discloses a simply constructed spreading roller which uses inclined fiber bundles that, upon contact with the web, deform slightly outwards in the direction of the inclination and thus transmit a spreading force to the web. Since the fiber bundles are inclined laterally outwards towards the end of the roller, starting from the center, a V-shaped annular gap is formed in the center of the roller, which can cause irritations on the web in the form of folds or creases, especially when the web is cut in the middle.

[0033] Even with spreading rollers that use single-track brush strips, zones without fiber bundles are created in the center of the roller. This occurs because the diagonally arranged fiber bundles are directed outwards from the center of the roller, making a V-shaped area without fiber bundles unavoidable.

[0034] The invention presented here is based on the objective of providing an improvement or an alternative to the prior art.

[0035] From a first perspective, the problem is solved by a support body for carrying spreading elements on a spreading roller, wherein the support body has a central longitudinal axis and at least one tooth element for positive axial connection of several support bodies to each other, wherein at least one mounting position for arranging a spreading element and / or at least one spreading element is arranged on the at least one tooth element of the support body.

[0036] In particular, the difficulties described above in connection with known spreading rollers of the same type can be overcome with the aid of the support body according to the invention.

[0037] By means of such a tooth element, or preferably several such tooth elements, several support bodies can advantageously be positively connected to one another, in particular by means of a tooth connection or gearing. Patent Attorneys 6

[0038] Thus, the present support structure allows for extremely flexible, yet structurally simple and cost-effective designs of various spreading rollers.

[0039] If a tooth element of the support body has one or more spreading elements, functional areas of a corresponding tooth connection or tooth elements thereof can advantageously be equipped with spreading elements.

[0040] The supporting body forms, for example, a sleeve part, an outer surface part of the spreading roller, whereby, when properly assembled, the outer surface part concentrically surrounds the central longitudinal axis or the axis of rotation.

[0041] At this point, the following should be explained immediately:

[0042] For the purposes of the invention, the term "tooth element" describes any projecting connecting element which is arranged on the head side of the respective support body and projects axially in such a way that a receiving gap or a tooth gap is arranged next to the connecting element or tooth element.

[0043] In this respect, a tooth element of a support body is designed to be able to engage in a tooth gap of another support body when the support bodies are moved towards each other along their central longitudinal axes and brought into effective contact with each other.

[0044] In other words, the tooth element is characterized by the fact that a material recess is arranged on the head side of the support body next to the tooth element, or usually two material recesses are arranged, which gives the tooth element an axially exposed position on the support body.

[0045] The matenal recess shapes the tooth gap on the supporting body.

[0046] Therefore, the tooth element, with a correspondingly complementary tooth gap, is designed to establish a positive-locking tooth connection between two support bodies and / or between a support body part and another component. Patent Attorneys 7

[0047] In addition, the tooth element increases the outer surface of the support body that can be effectively covered with spreading elements in the axial direction.

[0048] In any case, to create the positive locking tooth connection, two tooth elements are arranged interlocking at the connection point or connection area, whereby "interlocking" is defined by the fact that the tooth elements are arranged next to each other in the axial direction of the central longitudinal axis, at least partially.

[0049] In the context of the invention, the term "occupancy location" describes a receptacle or a designated receptacle on the outer surface of the support body, on which a wide-span element is or can be arranged.

[0050] In the present case, such a occupancy location can either be physically present (receiving), for example by means of a receiving bore, or only be provided (designated receiving location), for example by means of a marking.

[0051] The term "central longitudinal axis" refers to the axial length of the support body. In the properly assembled state, the central longitudinal axis runs in the direction of the rotational longitudinal axis of the spreading roller.

[0052] Preferably, the central longitudinal axis of the support body and the rotational longitudinal axis of the spreading roller are aligned with each other.

[0053] Where the term “axial” is used in connection with the invention, this term “axial” shall be understood as referring to the axial direction of the longitudinal axis of a component in question, in particular as referring to a longitudinal extent of this component.

[0054] Where the term "radial" is used in this context, it should be understood as referring to a transverse direction extending to the longitudinal axis, in particular a transverse direction extending orthogonally to the longitudinal axis. Patent Attorneys 8

[0055] The “spreading roller” is, in accordance with the present invention, designed to spread a planar web of material laterally in axial spreading directions of the spreading roller with spreading elements which, upon contact with the web of material, exert a spreading force on the web of material, transverse to its direction of travel or longitudinal extension.

[0056] According to the invention, the spreading roller is preferably a brush spreading roller.

[0057] Therefore, the present wide-drawn elements preferably comprise fiber bundles.

[0058] Preferably, such fiber bundles consist of a large number of fiber elements.

[0059] Furthermore, it should be expressly noted that, within the context of this patent application, indefinite articles and indefinite numerical expressions such as "one...", "two...", etc., are generally to be understood as minimum values, i.e., "at least one...", "at least two...", etc., unless the context or the specific text of a particular passage indicates that only "exactly one...", "exactly two...", etc., is meant. Furthermore, all numerical values, as well as information on process parameters and / or device parameters, are to be understood in a technical sense, i.e., as being subject to the usual tolerances. Even the explicit inclusion of the limitation "at least" or "at least" or similar should not be interpreted as meaning "exactly one" when simply using "one," i.e., without the indication of "at least" or similar.

[0060] If the support body has a large number of tooth elements for the positive axial connection of several support bodies to each other, support bodies, especially in the form of a sleeve part, can be advantageously connected to each other in a positive manner.

[0061] Two or more support bodies can be advantageously connected if at least one tooth element is formed axially on the head sides of the support body. Patent Attorneys 9

[0062] Furthermore, the axial alignment of at least one tooth element allows for the establishment of an axial tooth connection between two support bodies. In particular, this makes it possible to easily create a positive-locking connection.

[0063] If tooth elements are arranged on both sides of the support body, several support bodies can be easily connected to each other at their head sides.

[0064] A positive-locking connection can be easily created between support bodies if tooth elements on opposite end faces of the support body are identically designed.

[0065] In particular, identical tooth gaps can be achieved using identically designed tooth elements, thus enabling the establishment of identical tooth connections on both sides of the support body.

[0066] Thus, structurally identical or identical support bodies can be manufactured in a simple manner, with which different lengths of spreading rollers can be produced almost arbitrarily.

[0067] A particularly homogeneous tooth connection can be provided if tooth elements are arranged concentrically around the central longitudinal axis of the support body and are spaced apart from each other in the circumferential direction of the support body by a tooth gap to receive a complementarily designed tooth element.

[0068] Support bodies can easily be joined and connected together, in particular to form a cylindrical surface section of a spreading roller, if tooth elements are arranged offset from each other in the circumferential direction on opposite end faces of the support body, in particular offset from each other by a tooth gap for receiving a complementary tooth element. Patent Attorneys 10

[0069] Almost all common wide-profile rollers can be provided by means of the support body if tooth elements realize a toothing between at least two support bodies, wherein the toothing has a pitch of greater than or equal to 6, preferably greater than or equal to 20 and preferably greater than or equal to 36, and wherein the respective pitch is defined half by tooth elements and half by tooth gaps for receiving complementary tooth elements.

[0070] In order to keep the design effort regarding the gearing within a reasonable range, it is advantageous if the gearing has a pitch of less than or equal to 60, preferably less than or equal to 50 and particularly preferably less than or equal to 40.

[0071] An axial locking mechanism between two support bodies or between other components arranged on the head side of the support body can be easily integrated into the support body if at least one tooth element has axial bores, in particular axial through bores, for receiving a locking element.

[0072] A highly effective toothing system with a sufficiently large receiving surface for a mounting position for arranging at least one wide-span element on the at least one tooth element can be provided if the at least one tooth element has an element length of greater than or equal to 5 mm, preferably greater than or equal to 10 mm and particularly preferably greater than or equal to 15 mm.

[0073] The axial length of the gearing and in particular of tooth elements thereof can be advantageously selected if the at least one tooth element has an element length of less than or equal to 50 mm, preferably less than or equal to 30 mm and particularly preferably less than or equal to 20 mm.

[0074] The term "element length" is synonymous with the axial overhang depth of the respective tooth element. Patent Attorneys 11

[0075] Similarly, such an element length can also be seen as a measure of the depth of a tooth gap.

[0076] Furthermore, it is advantageous if at least one tooth element has an element length (overhang depth), the element length being chosen depending on the following characteristics:

[0077] • of the support body diameter, and / or

[0078] • the length of the load-bearing body, and / or

[0079] • the wall thickness of the supporting structure, and / or

[0080] • the length of the spreading elements, and / or

[0081] • the inclination of the lateral elements relative to the central longitudinal axis, and / or

[0082] • the diameter of the spreading elements, and / or

[0083] • the length of axial bores in fasteners

[0084] This allows the element length to be individually tailored to the specific requirements of a spreading roller to be manufactured.

[0085] The at least one tooth element can be expediently adapted to a support-side anchoring of the wide-span element if the at least one tooth element has an end face which is arranged with an angle of inclination relative to the central longitudinal axis which corresponds to the angle of inclination of wide-span elements.

[0086] Preferably, each tooth element has an end face that is arranged orthogonally to the central longitudinal axis. This allows the supporting body to be manufactured in a simple manner.

[0087] Using the present support body, a spreading roller can be manufactured in a structurally simple, modular manner if the support body has a cavity for receiving a support shaft section of a spreading roller, which is enclosed and bounded circumferentially by an inner surface of the support body, with an anti-rotation device acting between the support body and the support shaft section. Patent Attorneys 12

[0088] In the context of the invention, the term "support shaft part" describes a shaft part of the spreading roller on which a support body or preferably several support bodies connected to each other by means of a tooth connection are arranged twisted on the support shaft part, for example as a sleeve part.

[0089] The anti-rotation device can be designed in different ways, for example as a pin connection, a screw connection or the like.

[0090] The support body and the support shaft part can be connected to each other in a particularly simple and effective manner if the anti-rotation device has a tongue-and-groove connection, wherein at least one spring element is arranged on the inside of the support body to form the tongue-and-groove connection with a support shaft part.

[0091] If the support body features a spring element of the tongue-and-groove connection instead of a groove, a detrimental material weakening in a wall of the support body, which is designed as a sleeve component, can be avoided. This, in turn, eliminates the risk of the support body becoming structurally weakened due to multiple material weakenings related to the groove of the tongue-and-groove connection and, for example, to mounting holes for expanding elements.

[0092] The inside of the support body defines the cavity of the support body in which the support shaft part is at least partially arranged.

[0093] It is advantageous if a total of four spring elements are arranged on the inside of the support body to form the tongue-and-groove connection with a support shaft part, wherein the four spring elements are arranged concentrically around the central longitudinal axis, offset by 90° to each other.

[0094] On the one hand, this allows torques occurring at a spreading roller to be transmitted very efficiently between the support body and the radially inner support shaft section. Patent Attorneys 13

[0095] On the other hand, this allows for the provision of structurally identical support bodies which can be easily axially connected to each other.

[0096] Furthermore, the support bodies can be provided in a rotationally symmetrical manner, which can promote low-vibration rotation of the spreading roller even at higher rotational speeds.

[0097] This in turn allows a spreading roller to be mounted on more compact bearing units.

[0098] Two or more support bodies can be easily interconnected if at least one spring element extends along the central longitudinal axis from a tooth element on the first head side to a tooth gap on the second head side, which is opposite the first head side.

[0099] This allows, for example, two support bodies with their offset head sides (with tooth elements or tooth gaps) to be easily connected axially.

[0100] For this purpose, a support body is rotated by 180° around a transverse axis running orthogonally to the aligned central longitudinal axes of the two support bodies; subsequently, the two support bodies are moved axially towards each other and axially connected, i.e., virtually "back to back".

[0101] The spring element can be designed to extend axially from one tooth element to one tooth gap; however, it can also be designed with interruptions through material recesses in order to be implemented in a way that saves material and weight.

[0102] Furthermore, it is advantageous if the at least one spring element has a spring length that is greater than or equal to 50% of the total length of the supporting body, preferably greater than or equal to 70%, and particularly preferably greater than or equal to 80%. Patent Attorneys 14

[0103] This allows a rotationally rigid connection between the support body and the support shaft part arranged therein to be achieved, as far as possible over the entire longitudinal extent of the support body.

[0104] The support body can be manufactured with fewer moving masses and therefore with a lower weight if the spring length is less than or equal to 99% of the total length of the support body, preferably less than or equal to 95% and particularly preferably less than or equal to 90%.

[0105] The spring element can be designed particularly advantageously depending on the length of the support body if the at least one spring element has a spring length greater than or equal to 10 mm, preferably greater than or equal to 50 mm and particularly preferably greater than or equal to 100 mm, and / or has a spring length less than or equal to 1000 mm, preferably less than or equal to 800 mm and particularly preferably less than or equal to 500 mm.

[0106] The tongue-and-groove connection can be further well adapted to the dimensions of the supporting element, in particular to its wall thickness, if the at least one spring element has a spring height of greater than or equal to 1 mm, preferably greater than or equal to 2 mm and particularly preferably greater than or equal to 5 mm, and / or has a spring height of less than or equal to 12 mm, preferably less than or equal to 10 mm and particularly preferably less than or equal to 8 mm.

[0107] Cumulatively or alternatively, it is advantageous if the at least one spring element has a spring width of greater than or equal to 2 mm, preferably greater than or equal to 5 mm and particularly preferably greater than or equal to 8 mm, and / or has a spring width of less than or equal to 20 mm, preferably less than or equal to 15 mm and particularly preferably less than or equal to 10 mm.

[0108] This allows the spring element to be adapted almost arbitrarily, especially to the inner diameter of the support body. Patent Attorneys 15

[0109] Furthermore, the spring-groove connection can be additionally adjusted to meet the requirements of an anti-rotation device.

[0110] Spreading elements can be constructed in different ways, for example from a bendable single element.

[0111] If the present support body can be assembled from two or more components, i.e., is designed as a multi-part structure, it is advantageous if a locking element of the anti-rotation device, in particular a spring element of a tongue-and-groove connection, is designed as a coupling element for coupling support body components, in particular arc-shaped shell parts.

[0112] The coupling element can be advantageously implemented by the individual support body components on the assembled support body if the locking element of the anti-rotation device is designed in multiple parts.

[0113] This allows the coupling element to be composed of several coupling sections when the support body components are joined together to form the support body.

[0114] A particularly advantageous design variant can be implemented if at least one wide-span element has a fiber bundle.

[0115] Using such fiber bundles, it is possible to construct simple brush-like spreading elements and thus ultimately a correspondingly equipped brush spreading roller.

[0116] The fiber bundles contain a large number of individual fiber elements.

[0117] Since such fiber bundles and their fiber elements are already known from the prior art, their properties and functions will not be discussed further here.

[0118] The support body can be particularly advantageously equipped with spreading elements if at least one spreading element is located on an end face of the tooth element. Patent Attorneys 16

[0119] The front ends are spaced apart by a distance of less than or equal to 15 mm, preferably by less than or equal to 10 mm, and particularly preferably by less than or equal to 5 mm.

[0120] This allows spreading elements to be positioned extremely far out axially on the supporting body.

[0121] Furthermore, to ensure sufficient stability of the tooth element, it is advantageous if the face distance is greater than or equal to 1 mm or 2 mm. This allows a receiving bore to be positioned sufficiently far from the face of the tooth element, ensuring that enough material remains between the face and the receiving bore.

[0122] Excellent spreading effect on a web of material can be achieved even in the area of ​​a tooth connection if at least one spreading element is arranged at an angle to the central longitudinal axis.

[0123] Different spreading thicknesses can be achieved on a spreading roller if the at least one spreading element has an angle of inclination greater than or equal to 10°, preferably greater than or equal to 15° and particularly preferably greater than or equal to 20°, and / or has an angle of inclination less than or equal to 45°, preferably less than or equal to 40° and particularly preferably less than or equal to 35°.

[0124] The support body can advantageously be equipped with spreading elements extending axially far outwards, i.e., into its axial tip extension (tooth elements), if the support body has axial rows of spreading elements on its outer surface, wherein at least some rows of covering extend into the tooth elements of the support body.

[0125] These layers of infill preferably form straight infill lines on the outer surface of the supporting body. Patent Attorneys 17

[0126] However, user-specific alternative occupancy lines can also be provided, such as curved or curved occupancy lines, and corresponding occupancy rows.

[0127] In this case, an occupancy row is defined by at least two occupancy places, through which the straight occupancy line is arranged.

[0128] A support body densely populated with spreading elements can be produced if the axial rows of layers are arranged parallel to each other, in particular parallel to the central longitudinal axis of the support body.

[0129] Furthermore, an optimal effect for the lateral spreading of a flat web of material can be achieved with axially parallel rows of layers.

[0130] It has been shown that, especially at high web speeds, smoother web running can be achieved if the arrangement of axially oriented layers or corresponding spreader element rows is not exactly axially aligned, and in particular not exactly axially parallel to the central longitudinal axis, but rather at an angle to it, with the angle being located circumferentially on the outer surface. This can serve, for example, to distribute a lead-in point or area of ​​the web evenly across the entire spreader roll width. While the roll elements used, such as the support bodies, are not 100% identical in construction, but rather only designed to be structurally similar, the advantage here is that such an angle has hardly any significant adverse effect on the design of the roll center; and if it does, only a negligible one.

[0131] It is advantageous if the axial rows of layers are arranged inclined at an angle α, β of greater than or equal to 1° relative to the central longitudinal axis on the outer surface, preferably greater than or equal to 2° and particularly preferably greater than or equal to 3°, and / or at an angle Patent Attorneys 18

[0132] a, ß are arranged inclined at less than or equal to 20°, preferably at less than or equal to 18° and particularly preferably at less than or equal to 15°.

[0133] This results in a run-up zone of the web on the spreading roller not as an axis-parallel line, but the contact area between the web and the spreading roller can be distributed evenly across the spreading elements.

[0134] Advantageously, such an angle can be achieved on the outer surface of the support body between a fictitious axial longitudinal line, which runs parallel to the central longitudinal axis, and a row of teeth arranged at an angle to it, by having this row of teeth extend, for example, from a tooth element on a front head side of the support body to a tooth element on the rear head side, which is arranged in the circumferential direction of the support body next to the tooth gap, which is aligned with the tooth element on the front head side.

[0135] In accordance with the invention, support bodies that are excellently axially effective and at the same time easily axially connectable can be built if the axial rows of layers are arranged in the direction of the central longitudinal axis of the support body between a tooth element on the one hand and a tooth gap on the other.

[0136] A spreading roller can be easily assembled modularly if the tooth elements of adjacent axial rows of teeth are arranged axially opposite each other on the support body.

[0137] Existing support bodies can be connected to each other in a form-fitting manner particularly easily if the number of a division of tooth elements and tooth gaps is an odd number and the number of spring elements for forming a tongue-and-groove connection with a support shaft part is an even number, where the total number of covering rows is the product of these two numbers.

[0138] Therefore, it is advisable if the following configuration is implemented on the supporting structure:

[0139] 4*9=36, 2*19=38, where: patent attorneys 19

[0140] First number = leader, second number = division

[0141] Depending on the application, the supporting body can be realized with different axial spreading effects if the rows of layers are completely or only partially covered with spreading elements, whereby different layer densities always create an envelope on the supporting body, in particular an envelope with a circular cross-section.

[0142] The term “enclosing” is defined in the sense of the invention by a fictitious shell which encloses a spatial volume of a supporting body equipped with spreading elements, if this spatial volume is fictitiously covered by the shell.

[0143] Furthermore, it is advantageous if the supporting body has at least two parallel rows of coverings running side by side - with or without spreading elements - wherein one row of coverings of the at least two parallel rows of coverings runs further axially forward on the supporting body.

[0144] If a first row of occupancy is axially further forward than a second row of occupancy of at least two rows of occupancy, a further advantageous embodiment variant can be produced.

[0145] The supporting structure proposed here can also be constructed differently.

[0146] An advantageous design can be achieved if the supporting body is manufactured as a sleeve component.

[0147] A sleeve component can realize a ring-shaped, one-piece support body, which therefore inherently possesses high stability.

[0148] A multi-part support structure can be provided if the support structure is manufactured as an arc-shaped shell component.

[0149] In this process, a sleeve component can be assembled using two or more such arc-shaped shell components. Patent Attorneys 20

[0150] Preferably, the support body consists of two half-shell parts, which minimizes the number of joints on the support body.

[0151] Arc-shaped shell parts can be joined together well if the respective arc-shaped shell part has coupling elements on its two longitudinal edges running in the axial direction of the central longitudinal axis for coupling with at least one other arc-shaped shell part.

[0152] The two spaced-apart longitudinal edges of the arc-shaped shell part form two coupling sides of the arc-shaped shell part, at which two or more arc-shaped shell parts are connected to each other.

[0153] A clear and error-free coupling of arc-shaped shell parts can be achieved if the coupling elements are designed differently relative to each other on the two longitudinal edges.

[0154] If the coupling elements are arranged at different positions relative to each other on the two longitudinal edges in the axial direction of the central longitudinal axis, a simple coupling of arc-shaped shell parts can be achieved.

[0155] Arc-shaped shell parts can be designed to be identical yet connectable to each other if the coupling elements on the two longitudinal edges are designed to be complementary to each other.

[0156] The coupling elements can be used to implement the spring element described above, provided that the coupling elements are arranged to project radially further inwards along an inner side of the arc-shaped shell part.

[0157] Individual coupling elements or parts thereof can be arranged spaced apart from each other along the central longitudinal axis if the coupling elements are designed in multiple parts.

[0158] The coupling elements can expediently perform several functions simultaneously if the coupling elements incorporate at least one locking element to prevent rotation between the support body and a support shaft section. Patent Attorneys 21

[0159] Alternatively, the supporting body can also be manufactured as a straight strip. This provides another advantageous design option.

[0160] The supporting structure can be realized simply and with extreme structural strength if it is monolithic.

[0161] If the support body and at least one tooth element are monolithic, connecting elements for a positive locking connection can be integrated into the support body particularly easily and robustly.

[0162] As described above, it is advantageous if a plurality of spreading elements arranged on the supporting body form a cylindrical envelope on the supporting body.

[0163] The envelope is characterized by the radially outwardly directed ends (contact surfaces) of the spreading elements with respect to the central longitudinal axis, in particular by the ends (contact surfaces) of fiber elements of the fiber bundles.

[0164] In the present case, the enveloping structure has a circular cross-section, particularly in an unloaded state.

[0165] More precisely, the cylindrical envelope is defined by means of contact surfaces of the spreading elements for interaction with a web of material, whereby these contact surfaces are designed by means of the radially outer ends of the spreading elements.

[0166] Particularly advantageous design variants of the support body can be provided if the support body has, on the one hand, a division consisting of tooth elements and tooth gaps and, on the other hand, a radially more inwardly located anti-rotation device consisting of at least one locking element, whereby the following relationship between the division and the anti-rotation device results:

[0167] • The product of the division and the number of security elements yields the number of rows of occupancy, patent attorneys

[0168] • The division or the large number of occupancy sequences results in an odd number,

[0169] • The number of safety elements results in an even number.

[0170] From this, the following row possibilities can advantageously be derived with regard to the occupancy series:

[0171] Two locking elements result in a number of occupancy rows of 14, 18, 22, 26, 30, 34, 38, 42, 46 or 50, or

[0172] Four locking elements result in a number of occupancy rows of 12, 20, 28, 36, 44, 52 or 60, or

[0173] Six safety elements result in a number of occupancy rows of 18, 30, 42, 54, 66.

[0174] The securing elements arranged on the inside of the support body can be designed in different ways, for example as a spring element and / or as a groove of a tongue-and-groove connection.

[0175] According to a second aspect of the invention, the problem is solved by a support shaft part for a spreading roller for laterally spreading a planar web of material in axial spreading directions with spreading elements which exert a spreading force on the web when in contact with the web, with a shaft central longitudinal axis, wherein the support shaft part has at least one longitudinal groove for establishing a tongue-and-groove connection with a support body for carrying spreading elements on a spreading roller.

[0176] The proposed support shaft component allows for a particularly simple design to prevent rotation.

[0177] Furthermore, a spreading roller can be advantageously provided in a modular manner, particularly in connection with the present support body.

[0178] The support shaft component can also be referred to as a support roller. Patent Attorneys 23

[0179] An advantageous rotationally symmetrical component can be realized for the spreading roller if the support shaft part has a total of four longitudinal grooves, which are evenly distributed in the circumferential direction of the support shaft part.

[0180] A large number of support bodies in the form of strip parts can be advantageously arranged on the support shaft part if a large number of longitudinal grooves are arranged concentrically distributed around the central longitudinal axis of the support shaft part.

[0181] A plurality of longitudinal grooves can be arranged concentrically around the central longitudinal axis of the support shaft section, if the at least one longitudinal groove is bounded by two longitudinal side walls, wherein the two longitudinal side walls bounding the longitudinal groove enclose an angle of greater than or equal to 5° with each other, preferably greater than or equal to 10° and particularly preferably greater than or equal to 15°, and / or enclose an angle of less than or equal to 45° with each other, preferably less than or equal to 30° and particularly preferably less than or equal to 20°.

[0182] In particular, this allows a v-shaped longitudinal groove to be provided, which makes it possible to anchor support bodies particularly stably to the support shaft part.

[0183] The V-shaped longitudinal groove can widen radially outwards with its V-shape and thus open, or alternatively be designed in a V-shape directed radially inwards.

[0184] A particularly secure fixing of support bodies to the support shaft part can be achieved if at least one longitudinal groove is provided for forming a dovetail connection with the support body.

[0185] If the support shaft part is also a hollow shaft, it can be provided with less mass.

[0186] According to a third aspect, the object of the invention is solved by a roller part for a spreading roller with a roller part longitudinal axis, wherein the roller part has a support body according to the invention according to one of the features described here, Patent Attorneys 24

[0187] two or more interconnected such support bodies, and / or a support shaft part according to one of the features described here.

[0188] If the present roller part is characterized by the proposed support body and / or by the proposed support shaft part, the roller part can be manufactured in a modular and versatile manner with the advantages described above.

[0189] Different roller parts for manufacturing different spreading rollers can be produced structurally easily if two or more support bodies are operatively connected to each other by means of a positive locking connection, in particular by means of a multi-tooth connection.

[0190] Furthermore, the proposed roller part can be manufactured particularly cost-effectively if two or more support bodies of the roller part are identical.

[0191] The roller part can be manufactured in a variety of ways, including a sleeve part, an arc-shaped shell part, a straight strip part, or a combination thereof.

[0192] For example, a particularly simple construction can be achieved if two shell parts are designed as half-shells.

[0193] In the direction of the longitudinal extension of the roller part, differently oriented spreading elements can be arranged particularly close to each other on the roller part if the roller part has at least one coupling area between two or more support bodies, wherein the support bodies coupled to each other are arranged interlocking in the coupling area.

[0194] Since the support structures are preferably of identical construction, these support structures can be arranged in an interlocking manner, i.e., they can also be mounted "back to back". Patent Attorneys 25

[0195] If the roller part is designed to be ring-gap-free along its longitudinal extent with respect to spreading elements, an excellent spreading effect can already be achieved in this coupling area.

[0196] If two or more support bodies are axially toothed together on the support shaft part in accordance with the invention with respect to the present roller part, spreading elements can be arranged without annular gaps over the entire effective surface of a spreading roller if first spreading elements are inclined from the center of the roller part towards a first end face of the roller part and further spreading elements are inclined in the opposite direction towards a further end face of the roller part.

[0197] An uninterrupted effective surface in this respect can be achieved on the spreading roller if, in the circumferential direction of the roller part, tooth elements of two coupled support bodies arranged directly next to each other have spreading elements arranged at different inclinations.

[0198] A suitable design variant of the roller part can be achieved if differently inclined spreading elements exhibit opposite spreading effects, whereby the opposite spreading effects of tooth elements arranged directly next to each other in the circumferential direction of the roller part neutralize each other.

[0199] Support bodies installed on the roller part, in particular support bodies arranged on the support shaft part, can interact with the support shaft part by friction fit or by means of a clearance fit with respect to their inner surface, in particular with respect to a surface area of ​​the inner surface of greater than or equal to 50%, preferably of greater than or equal to 70% and particularly preferably of greater than or equal to 90%.

[0200] Alternatively, it is advantageous if a support body is arranged concentrically around a support shaft section, the support body being spaced apart from the support shaft section by means of a gap. Patent Attorneys 26

[0201] In this case, the support body and the support shaft part can, for example, only be in contact with each other at the tongue-and-groove connection, which can significantly simplify the assembly of the roller part.

[0202] According to a fourth aspect of the invention, the problem is solved by a spreading roller, in particular a brush spreading roller, for laterally spreading a planar web of material in axial spreading directions with spreading elements which exert a spreading force on the web of material when in contact with the web, and with a longitudinal axis of rotation, wherein the spreading roller has an outer surface part running concentrically around the longitudinal axis of rotation, which has one or more tooth elements extending in the longitudinal axis of rotation.

[0203] By means of the tooth elements extending in the longitudinal axis of rotation, components of the spreading roller can be advantageously joined together in a modular, toothed configuration.

[0204] The outer surface of the casing can also be a single piece and, for example, interlock with end cap parts or the like.

[0205] Preferably, the outer surface of the shell is made up of multiple parts.

[0206] A tooth connection that is advantageous on the spreading roller can be created if the tooth element or tooth elements of the outer surface part have a circumferentially acting toothing.

[0207] The spreading roller can be advantageously constructed with regard to its axially acting spreading effects if the tooth element or tooth elements form a part of the outer surface of the outer part of the outer surface, wherein at least one spreading element is arranged on a tooth element.

[0208] According to a fifth aspect of the invention, the problem is also solved by a spreading roller, in particular a brush spreading roller, for laterally spreading a planar web of material in axial spreading directions with spreading elements, which are described in Patent Attorneys 27

[0209] Contact with the web exerts a spreading force on the web, and with a longitudinal axis of rotation, wherein the spreading roller is characterized by a support body according to the invention according to one of the features described here, and / or a support shaft part according to one of the features described here, and / or a roller part according to one of the features described here.

[0210] This allows the spreading roller to be designed in a modular, particularly simple and versatile way, and also with particularly good spreading effects in the two axial spreading directions of the spreading roller.

[0211] It is particularly advantageous if the toothing of support ring bodies, especially in their respective roller centers, is designed such that the fastening bores for the first layer row (bundle row) extend into the other roller half as far as is determined by the sum of the projection of the wide-stretch element (fiber bundle) and the minimum wall thickness, and the total tooth length is twice this penetration depth.

[0212] According to a sixth aspect of the invention, the problem is solved by a method for manufacturing a spreading roller in which at least two support bodies for carrying spreading elements are joined together by means of toothing, and in which tooth elements of the toothing are equipped with one or more spreading elements. This allows the spreading roller to be designed in a modular, particularly simple and versatile manner, and also with particularly good spreading effects in the two axial spreading directions of the spreading roller.

[0213] It hardly matters whether the wide-stretching elements are arranged before the toothing of the support bodies on tooth elements thereof, or only after the support bodies have been toothed together.

[0214] According to a seventh aspect of the invention, the problem is also solved by using a tooth element of a spreading roller for arranging a spreading element. Patent Attorneys 28

[0215] for the lateral spreading of a flat web of material in axial spreading directions of the spreading roller.

[0216] This allows the spreading roller to be designed in a modular, particularly simple and versatile way, especially with the help of a tooth connection or toothing.

[0217] On the other hand, an outer toothed surface of the support body can be used to its maximum extent with regard to the covering with spreading elements, especially at a tooth connection.

[0218] Furthermore, this avoids an annular gap area at the tooth connection or toothing with regard to the spreading elements, so that the spreading roller can be designed with particularly good spreading effects in the two axial spreading directions of the spreading roller.

[0219] In any case, different solutions can be provided in which almost any axial roller size can be provided by means of several support bodies, in particular by means of several fiber bundle support bodies, which are preferably each identical in design and with which the following properties can be achieved simply and effectively:

[0220] • Only one fiber bundle support body for each roller diameter

[0221] • Elimination of the v-shaped annular gap

[0222] • All fiber bundles are aligned in the same direction (axially) and at the same inclination

[0223] • Spreading force from the center of the roller continuously to the end of the roller

[0224] • Highly flexible fiber bundle arrangements

[0225] • Various fiber bundle arrangements can be combined

[0226] • Effective anti-rotation device

[0227] • Easy assembly

[0228] • Low storage costs Patent attorneys 29

[0229] Similar results can also be achieved with brush spreading rollers with brush strips if they are designed in such a way that defects in the fiber bundles in the center of the roller are avoided by suitable measures, which can also be achieved with simple solutions.

[0361] It should be noted that all reference marks “nn” in the second part of the figures should be understood as “ll-nn”.

[0362] According to the illustrations in Figures 1 to 17, exemplary first embodiments of a first variant of support bodies 1A, 1B and 1C for carrying spreading elements 2 (numbered only by way of example) for a spreading roller 100 (also numbered only by way of example, see for example Figure 15) are shown.

[0363] The spreading elements 2 are designed as fiber bundles (not numbered again) consisting of a large number of fiber elements (not shown individually).

[0364] Therefore, the support structures 1A and 1B are also referred to as fiber bundle support structures.

[0365] As can be clearly seen, particularly with regard to a first embodiment according to the illustration in Figure 1, the support body 1A is designed as a sleeve part 4, which in turn is manufactured as an injection-molded part (not further numbered). Patent Attorneys 45

[0366] The support body 1 A has a central longitudinal axis 6 along its longitudinal extent, around which the support body 1A can rotate with the spreading roller 100.

[0367] Therefore, when properly mounted on the spreading roller 100, the central longitudinal axis 6 of the support body is aligned with its rotational longitudinal axis 102.

[0368] Furthermore, the support body 1A has a cavity 8 which is bounded by an inner surface 10 of the support body 1A.

[0369] The support body 1A further has an outer surface 12 which is arranged radially further outwards in the radial direction 14 of the central longitudinal axis 6.

[0370] The outer lateral surface 12 is arranged concentrically around the central longitudinal axis 6 in the circumferential direction 16 of the support body 1A.

[0371] Furthermore, the support body 1A has a front head side 18 (front) and its rear head side 20 (back).

[0372] The front head side 18 is a front axial end 18A of the support body 1A and the rear head side 20 is a rear axial end 20A of the support body 1A.

[0373] On each head side 18, 20 tooth elements 22 (numbered only as examples) are arranged, which form a corresponding toothing 23 there.

[0374] Between the tooth elements 22, corresponding tooth gaps 24 (numbered only as examples) are arranged, wherein the tooth elements 22 and the tooth gaps 24 are arranged alternately to each other in the circumferential direction 16 of the support body 1A.

[0375] Each tooth element 22 projects axially further forward with its respective end face 22A on the support body 1A.

[0376] Therefore, the total length (not shown separately) of the supporting body 1A extends along its central longitudinal axis 6 from end face 22A to end face 22A. Patent Attorneys 46

[0377] The end faces 22A of the toothing 23 can be perpendicular to the central longitudinal axis 6; however, they can also be adapted to an inclination angle 2A of spreading elements 2.

[0378] Such an angle of inclination 2A is shown and indicated, for example, in Figure 16.

[0379] However, the tooth elements 22 on the front head side 18 and on the rear head side 20 are each offset from each other by a tooth gap 24 in the circumferential direction 16.

[0380] In any case, the teeth 23 on the head sides 18 and 20 are identical.

[0381] In this respect, the front head side 18 (front) of a first support body 1A and the rear head side 20 (back) of a further support body 1A can be axially pushed into one another along their central longitudinal axes 6 and interlocked with each other in a form-fitting manner, as shown in the illustration according to Figure 2.

[0382] In order to make it structurally easy to implement different arrangements 28 of wide-span elements 2 on the support body 1A, the support body 1A has a large number of occupancy locations 30 on its outer surface 12, which are designed to be able to hold one wide-span element 2 permanently on the support body 1A.

[0383] A special feature here is that such occupancy positions 30 are also arranged on the tooth elements 22, whereby at least one wide-span element 2 can be expediently arranged on tooth elements 22 of the support body 1 A.

[0384] Therefore, spreading elements 2 can be arranged axially as far out as possible on the support body 1 A, in particular on the teeth 23 of the support body 1A.

[0385] A plurality of such occupancy locations 30 forms an occupancy row 32, wherein the occupancy row 32 is preferably a straight occupancy line (not again patent attorneys 47

[0386] numbered) are arranged running between the head sides 18 and 20 of the support body 1A.

[0387] Such occupancy series 32 can also be referred to as machining series, since the occupancy locations 30 may be, for example, markings or bores, or the like, which are attached to or machined on the support body 1 A.

[0388] More precisely, a row of contacts 32 runs from a tooth element 22 on one side to a tooth gap 24 axially opposite this tooth element 22 on the other side.

[0389] The support structure 1A has a plurality of rows of layers 32, which are also arranged parallel to each other. In particular, the rows of layers 32 run parallel to the central longitudinal axis 6.

[0390] Furthermore, the rows of occupancy 32 are arranged concentrically around the central longitudinal axis 6 in the circumferential direction 16 with a division 34.

[0391] The division 34 is composed of the multitude of tooth elements 22 and tooth gaps 24, which are arranged alternately one behind the other in the circumferential direction 16 of the support body 1A on a head side 18 or 20.

[0392] Furthermore, the support body 1A has locking elements 39 of an anti-rotation device 40, by means of which the support body 1A can be secured against rotation on a support shaft part 42 (see, for example, Figure 14) of a spreading roller 100, when this support shaft part 42 is inserted into the cavity 8 of the support body 1A.

[0393] The locking elements 39 of the anti-rotation device 40 are arranged, among other places, on the inside 10 of the support body 1A.

[0394] For example, the anti-rotation device 40 is implemented as a tongue-and-groove connection 44 (see, for example, Figure 21, right-hand illustration), which acts between the support body 1 A and the support shaft part 42. Patent attorneys 48

[0395] In this case, at least one spring element 46 is formed on the inside 10 of the support body 1A and extends with its spring construction length (not separately numbered) in the direction of the central longitudinal axis 6.

[0396] A spring height (not shown separately and numbered) of the at least one spring element 46 extends in radial direction 14 further radially towards the central longitudinal axis 6.

[0397] A spring width (not shown separately and numbered) of the at least one spring element 46 accordingly runs transversely to the spring length and the spring height.

[0398] In this first embodiment, the support body 1A has a total of four such spring elements 46, which are arranged evenly around the central longitudinal axis 6 of the support body 1A.

[0399] The support shaft part 42 has correspondingly complementary arranged and designed longitudinal grooves 48 (see, for example, Figure 14) of the spring-groove connection 44, as will be described in more detail later.

[0400] In the present first embodiment, a 36-part pitch 34 is used, with 18 tooth elements and correspondingly 18 tooth gaps, each of which is wedge-shaped.

[0401] Inside (cavity 8) of the support body 1A are the locking elements 39 of the anti-rotation device 40, which here comprise four spring elements 46, which are arranged on the inside 10 at 90°.

[0402] However, in the case of the sleeve part 4, which serves as support body 1A, only two spring elements can be attached at an angle of 180°.

[0403] This design – for example, with a 36-point pitch and 4-fold anti-rotation device – allows the assembly of several 1A support bodies in the same or opposite mounting directions. Patent Attorneys 49

[0404] This means that in a back-to-back assembly, the structure can be rotated by a 36-unit division, which is advantageous in order to achieve a uniform and identical structure on both sides.

[0405] The diameter 50 of the support body 1A and its length 52 can be selected almost arbitrarily. The division with respect to the number of rows 32 (machining lines), which in this case is a division of 36, can be adjusted using appropriate calculation rules.

[0406] The occupancy rows 32 or occupancy lines are normally arranged axially, but they can also be designed at an angle.

[0407] The toothing 3 is shown as an example of a cone or truncated cone, but it can also be used as any other sliding shape, such as a rectangle.

[0408] According to the illustration in Figure 2, an arrangement 56A consisting of two identically constructed support bodies 1A (fiber bundle support bodies) is shown, which are axially pushed into one another at a dome area 58 with their toothings 23.

[0409] In this respect, the coupling area 58 and thus a positive locking connection 60 in the form of a multi-tooth connection (not numbered again) is formed by means of the toothing 23 of the two support bodies 1 A.

[0410] On the left support body 1A, some axial rows of occupancy 32 are clearly visible, as well as tangential perimeter lines 32A.

[0411] The intersection points 32B of these occupancy series 32 and occupancy perimeter lines 32A represent the possible occupancy locations 30 (fiber bundle locations) on the outer shell surface 12.

[0412] As will be shown according to different occupancy densities (see especially Figures 7 to 9), corresponding occupancy sites 30 (fiber bundle anchorages) can be provided at these intersection points 32B; however, they can also be only partially occupied and used with spreading elements 2. Patent Attorneys 50

[0413] The identically shaped toothing 23 is provided at the two axial ends 18A and 20A of the support body 1A, which can be connected together arbitrarily at the axial ends 18A, 20A.

[0414] A certain tooth depth 22B on a tooth element 22 is required to ensure that, even when the support bodies 1A are pushed together in such a way that their spreading elements 2 point in different spreading directions 62A and 62B (see approximately Figure 15), which is necessary in a roller center 104, a closed envelope 64 is created to avoid a v-shaped annular gap (not shown) that is otherwise common in the prior art.

[0415] The tooth depth 22B can be calculated using the values ​​of the geometric conditions present on the support body 1A, for example by a length of covering rows 32, a length of fastening holes of the spreading elements 2, an inclination angle of the spreading elements 2, a diameter of the spreading elements 2 and / or a minimum wall thickness of the support body 1A or of the tooth element 22.

[0416] The tooth depth 22B can range from approximately 10 mm to 35 mm with normal dimensioning of the support body 1A.

[0417] According to the illustration in Figure 3, the support body 1A is shown again with an exemplary arrangement 28 of spreading elements 2.

[0418] It should be noted that the aforementioned features, effects, and advantages also apply to the object depicted in Figure 3. Therefore, reference is made to the preceding description, and only the essential differences will be explained below to avoid repetition.

[0419] In any case, the wide-plug elements 2 are attached along the occupancy rows 32. Patent attorneys 51

[0420] The distribution of the spreading elements 2 can be determined almost arbitrarily along the occupancy rows 32 according to the process requirements of the use of the spreading roller 100.

[0421] However, the supporting body 1A should be rotationally symmetrical and the envelope 64 should always have a circular cross-section.

[0422] It is clearly visible that the division of spreading elements 2 extends to the tooth elements 22.

[0423] This prevents the formation of a v-shaped annular gap in the circumferential direction 16 of the support body 1A when the tooth elements 22 of the support bodies 1A are pushed together and the spreading elements 2 are overlapped in the respective edge area of ​​the support bodies 1A, which would always have a disruptive effect on the spreading action of a spreading roller 100.

[0424] The arrangement 28 of the spreading elements 2 on the support body 1A according to the embodiment according to figure 2 enables a bundle covering of 100% on the spreading roller 100 according to figure 17 (see also arrangement according to figure 9).

[0425] According to the representation in Figure 4, a further arrangement 56B of two interconnected support bodies 1 A according to Figure 3 is shown, in particular the interior of the support bodies 1 A.

[0426] The continuous locking elements 39 of the anti-rotation device 40 are clearly visible, the locking elements 39 being axially assembled by the spring elements 46 of the two support bodies 1 A.

[0427] The locking elements 39 or the spring elements 46 are guided in complementary longitudinal grooves 48 of the support shaft part 42 when properly assembled.

[0428] The locking elements 39 and the spring elements 46 can extend over the entire length of the arrangement 56B consisting of the two support bodies 1A. Patent Attorneys 52

[0429] They can also be designed with interruptions along the central longitudinal axis 6, or only be attached at the axial ends 18A or 20A of the support bodies 1A.

[0430] According to the representation in Figure 5, an arrangement 56C of three support bodies 1A not yet connected to each other is shown according to Figures 3 and 4, which are positioned aligned with each other on a common central longitudinal axis 6.

[0431] The arrangement 56C has a left support body 1A with spreading elements 2 inclined to the left and two right support bodies 1A with spreading elements 2 inclined to the right.

[0432] If the support bodies 1A are now pushed together according to the direction of movement 11, an occupancy pattern can result in which an unfavorable V-ring gap at the coupling areas 58 of the support bodies 1A is always avoided.

[0433] This is very important, since the resulting spreading directions 62A and 62B (see Figure 15) on the respective equipped wide-spreading roller 100 are directed from the roller center 104 to the right and left respectively to the respective roller end 106A and 106B, which is also an important objective of the present invention.

[0434] For example, the distribution of spreading elements 2 on the left and middle support bodies 1A is such that on each occupancy row 32 spreading elements 2 are positioned, but on the right support body 1A only every second occupancy row 32 is equipped with spreading elements 2.

[0435] The density of the covering on spreading elements 2 can therefore also be adapted to the process-related requirements of a spreading roller 100.

[0436] As shown in Figure 6, an embodiment of an alternative support body 1B is depicted, which is constructed essentially identically to the previously described support body 1A. In this respect, only the differences of the patent attorneys 53

[0437] Supporting body 1B is described. Otherwise, reference is made to the preceding description to avoid repetition.

[0438] The alternative support body 1B has only two spring elements 46, which are arranged opposite each other. In other words, the anti-rotation device 40 of the alternative support body 1B has only two locking elements 39.

[0439] The arrow marking 70 clearly shows that on the front side of the head 18, the spring element 46 located above extends to the tooth gap 24, while the opposite and therefore lower spring element 46 extends to the tooth element 22, which is also opposite the aforementioned tooth gap 24.

[0440] On the rear head side 20, this is reversed.

[0441] Therefore, for the supporting body 1B, a total of 30 rows of occupancy 32 result, which is determined by the number of spring elements 46 and the division 34, namely with two spring elements 46 and a division of 15.

[0442] Otherwise, the structure of support body 1B corresponds to the structure of support body 1A.

[0443] According to the illustrations in Figures 7, 8 and 9, further arrangements 56D, 56E and 56F made of several support bodies 1A are shown as examples, wherein the arrangements 56D, 56E and 56F have different coverings 28 with different covering densities.

[0444] The arrangement 56D (Figure 7) features a covering 28 with a covering density of only 50%. This covering density is advantageously applicable when dealing with a relatively thick or insensitive web 68 (shown only by way of example with regard to Figure 15).

[0445] The arrangement 56E (Figure 8) has a layout 28 with a occupancy density of 66%. Patent Attorneys 54

[0446] The arrangement 56F (Figure 9) has a occupancy 28 with an occupancy density of 100%.

[0447] In the arrangements 56D, 56E and 56F, an irregularity in the form of an undesirable V-gap circumferentially 16 (see Figure 1) is avoided in the designated roller center 104 by means of sufficient covering.

[0448] Since the arrangements 56D, 56E and 56F always use the identical support body 1A, it is also possible to combine differently configured support bodies 1A.

[0449] According to the illustration in Figure 10, another support body 1C is shown, whose tooth elements 22 and tooth gaps 24 are rectangular in shape, and is accordingly equipped with rectangular teeth 23, both on its front head side 18 and on its rear head side 20.

[0450] Otherwise, the other support body 1C is identical to the support body 1A, so that with regard to the further features of the other support body 1C, reference is made to the description of the support body 1A in order to avoid repetition.

[0451] According to the representation in Figure 11, a developed section 72 of an arrangement 56G of several interconnected support bodies 1C is shown with respect to a central dome area 58 with the rectangular toothing 23.

[0452] In arrangement 56F, the support bodies 1C are mounted back-to-back such that, at the designated roller center 104, spreading elements 2 of the right support body 1C are inclined to the right, and spreading elements 2 of the left support body 1C are simultaneously inclined to the left. The toothing 23 with a tooth depth 22B is located at the roller center 104. Patent Attorneys 55

[0453] Therefore, the spreading elements 2 of the left support body 1C extend beyond the roller center 104 into the area of ​​the right support body 1C, and vice versa.

[0454] This cancels out the effects of the opposing spreading directions 62A and 62B in the center of the roller 104.

[0455] Since the spreading elements 2 of the left support body 1C and the spreading elements 2 of the right support body 1C act in opposite spreading directions 62A and 62B in the center of the roller 104 and are always directly adjacent to each other in the circumferential direction 16 (see Figure 1), their effects cancel each other out. However, their existence is necessary to avoid the undesirable V-shaped annular gap from the prior art.

[0456] Otherwise, please refer to the description above to avoid repetition.

[0457] As illustrated in Figures 12 and 13A and 13B, further arrangements of four support bodies 1C with a straight toothing 23 are shown by way of example; namely once in an unassembled state according to the illustration in Figure 12 and once in an assembled state according to the illustrations in Figures 13A and 13B.

[0458] Here, the two right-hand support bodies 1C have right-leaning spreading elements 2, and the two left-hand support bodies 1C have left-leaning spreading elements 2.

[0459] While the spreading elements 2, according to the illustrations in Figures 12 and 13A, are arranged parallel to the axial direction (fictitious axial longitudinal line) of the central longitudinal axis 6 on the outer surface 12 with respect to their layering rows 32, the layering rows 32, according to the illustration in Figure 13B, are arranged at an angle α or β to the axial direction (fictitious axial longitudinal line) of the central longitudinal axis 6 on the outer surface 12. Patent Attorneys 56

[0460] As illustrated in Figure 14, an exemplary solution for a support shaft section 42 with a central longitudinal axis 43 is shown, onto which support bodies 1A, 1B, 1C, or 1D can be mounted. In this embodiment, the support shaft section 42 is equipped with four longitudinal grooves 48 (numbered for illustrative purposes only). These longitudinal grooves 44 form the guides for the locking elements 38 of the anti-rotation device 40 and thus also, in particular, for the spring elements 56 of the respective support body 1A, 1B, 1C, or 1D with respect to the spring-groove connection 44. In the solution shown here as an example, a total of four longitudinal grooves 44 are provided, extending over the entire length of the support shaft section 42, not including the lateral bearing elements 42A arranged on both sides of the support shaft section 42.

[0461] These lateral bearing elements 42A each have a support shaft stub and are fixedly connected to a fixed frame or similar by means of suitable running bearings, thus enabling the free rotation of the complete spreading roller 100, as shown by way of example in the illustration according to figure 15.

[0462] As shown in Figure 15, the web 68 runs over the freely rotatable spreading roller 100, which is normally driven by the web 68. With a symmetrical arrangement of the spreading elements 2, the spreading roller 100 can be operated in both directions of rotation about its longitudinal axis of rotation 102. The solution for the roller center 104 is noteworthy. At the roller center 104, the support elements are arranged such that their spreading directions 62A and 62B are directed from the roller center 104 to the outer roller end 106A and 106B, respectively.

[0463] In particular, in brush spreading rollers 100 with inclined spreading elements 2, the resulting V-shaped annular gap, which is previously free of spreading elements 2, is successfully avoided in the roller center 104 by ensuring that the spreading elements 2 are positioned so closely together by being pushed together and the resulting overlap that the spreading effect of the spreading elements 2.1 and 2.2 begins directly in the roller center 104. Patent Attorneys 57

[0464] In this embodiment, it is advantageous that all spreading elements 2 have the same direction of action, namely parallel to the axis, and furthermore, that all spreading elements 2 have the same angle of inclination 2A (either to the right of the roller center 104 or to the left of the roller center 104), so that under pressure from the web 68, all spreading elements 2 undergo the same deformation, resulting in the same change in diameter for all spreading elements 2. This is particularly advantageous for smooth operation when the web 56 is not elastic, for example, in the case of thin metal foils.

[0465] Only in the center of the roller 104 are the support bodies mounted “back-to-back”.

[0466] All other supporting bodies of an arrangement are joined together in the same direction, thus resulting in a uniform and consistent surface structure, the division of which within the basic order of the occupancy rows 32 can be determined according to the requirements of the application parameters.

[0467] According to the illustration in Figure 16, another arrangement is shown in a detailed view, in which the alignment of spreading elements 2 with identical support bodies 1C pushed together with exemplary rectangular toothing 23 (but can also apply to other support bodies) of a designated roller center 104 is shown.

[0468] The spreading elements 2 of the right support body 1C are directed to the right, while the spreading elements 2 of the left support body 1C are directed to the left. Both spreading elements 2 project beyond the roller center 104 by a certain amount, contrary to their spreading direction.

[0469] In the case of a tooth 23 with a tooth depth 23A (at least twice the tooth depth 22B), the half extending beyond the roller center 104 is determined by the projection 74 of the inclined wide-span element 2 and a minimum wall thickness 76 opposite the face 22A of a tooth element 22. Since these two dimensions are taken into account on both sides of the roller center 104, the total tooth depth 23A is twice this value. (Due to patent attorneys 58)

[0470] These relationships allow the required tooth depth 22B of a tooth element 22 to be calculated accurately.

[0471] At axial butt points 23B (numbered only as examples) of tooth elements 22 of the gearing 23, a broad-extending element contact surface is missing.

[0472] As shown in Figure 17, a spreading roller 100 is depicted, which is mounted according to the arrangement shown in Figure 15. In addition to this arrangement, the spreading roller 100 is characterized by a support shaft part 42 according to Figure 14 and has lateral end caps 108 (numbered for illustrative purposes only). In operation, the spreading roller 100 rotates with a web of material 68 (see, for example, Figure 15) about its longitudinal axis of rotation 102. An outer surface part 110 of the spreading roller 100 can be provided, for example, by means of the support bodies 1C.

[0473] According to the illustrations in Figures 18 to 25, further exemplary embodiments of a second variant are shown on support bodies 1D, 1E and 1F for carrying spreading elements 2 (numbered only by way of example) for a spreading roller 100 (also numbered only by way of example).

[0474] As illustrated in Figures 18 and 19, another solution for a support body 1D for modularly simple spreading rollers 100 is shown by way of example. These rollers can be assembled solely from individual parts, almost all of which are identical in design. This further solution essentially consists of using, instead of support bodies 1A, 1B, 1C with sleeve part 4 for the support body 1D, alternatively arcuate shell parts 80, in particular half-shell parts, which are designed according to the same criteria as the support bodies 1A, 1B or 1C described above, and which, after assembly, look exactly like the support body 1A, 1B or 1C.

[0475] The advantage of this solution lies in the reduced design effort, simpler assembly, and lower costs for small production runs. Patent Attorneys 59

[0476] To avoid repetition, only the differences between support body 1D and support bodies 1A, 1B, and 1C with sleeve part 4 are described. For all other common features, please refer to the preceding description.

[0477] As shown in Figure 18, the two arc-shaped shell parts 80, also called half-shells 80 for short, are not yet joined together. The two half-shells 80 are identical in construction. They are designed like support bodies 1A, 1B, and 1C, respectively, and can also have the same dimensions, which offers advantages when programming bundling machines. Furthermore, they are designed so that they can be easily and almost backlash-free mounted via the coupling elements 82 (numbered only as examples). The coupling elements 82 have bores 82A for receiving dowel pins or pin elements 82B (not shown here, but see Figure 23) or the like, whereby the bores 82A can also pass through tooth elements 22 of the gear teeth 23.

[0478] The coupling elements 82 form spring elements 46 of a tongue-and-groove connection 44 (see Figure 21) on the inside 10 of the support body 1E, or vice versa. This significantly reduces the construction effort.

[0479] As shown in Figure 19, the ready-to-assemble support body 1D (double half-shell) is shown with an arrangement of widening elements 2 already attached to it, the arrangement having a covering 28 with a covering density of 100%. A drawn separation joint 83 indicates the longitudinal edges 84 of the two half-shells 80, on which the coupling elements 82 are formed.

[0480] According to the illustrations in Figures 20 and 21, another supporting body 1E made of two arc-shaped shell parts 80 is shown as an example, which basically has the same structure as the supporting body 1D shown in Figures 18 and 19.

[0481] In particular, Figure 21 shows again that the support body 1E has a 9-part division 34, with a total of 4 spring elements 46 or patent attorneys 60.

[0482] Safety elements 39. In this respect, the support body 1 E has a total of 36 rows of occupancy 32 of spreading elements 2.

[0483] According to the right-hand representation of Figure 21, a roller part 86 consisting of the support shaft part 42 and support body 1E is shown in a sectional view.

[0484] The roller part 86 has a roller part center axis 86A.

[0485] On the support body 1E, a plurality of covering rows 32 are arranged concentrically around the roller part central axis 86A in circumferential direction 16, with the spreading elements 2 forming the envelope 64.

[0486] As shown in Figures 22 and 23, another supporting body 1 F made of two arc-shaped shell parts 80 is shown as an example.

[0487] Figure 22 schematically shows a longitudinal section of an upper and a lower shell part 80, which are identical in construction and represent the same component, as well as the principle of joining them using coupling elements 82. These coupling elements are provided with bores 82A on both sides, so that in a properly assembled state of the two shell parts 80, their position relative to each other is fixed by a pin element 82B (see Figure 23).

[0488] As shown in Figure 23, the upper shell part 80 is mounted on a support shaft part 42, with the upper shell part 80 being held on both sides of the support shaft part 42 by the coupling elements 82, which simultaneously form spring elements 46 of a tongue-and-groove connection that are inserted into longitudinal grooves 48 (see especially Figure 14) of the support shaft part 42. The connection to the lower shell part 80 is made by means of the coupling elements 82, with the connection being secured by the pin elements 82B. The bores 82A (see Figure 22) are positioned in the area of ​​the guide and the coupling elements 82 such that the spreading elements 2 can be inserted on the outside without restriction. For assembly, the arc-shaped shell parts 80 can also be pre-assembled and slid onto the support shaft part 42. Although the arched shell parts 80 about the assembly patent attorneys 61

[0489] The gaps between the elements are positively connected; the cohesion should preferably be additionally secured via the pin elements 82B.

[0490] As shown in Figures 24 and 25, the further supporting body 1F is shown again in cross-section as an example.

[0491] As shown in Figure 24, a schematic cross-section of the upper shell part 80, which is fixed to the support shaft part 42, is shown.

[0492] As shown in Figure 25, a schematic cross-section of the lower shell part 80 is shown, as it is attached to the support shaft part 42 with mounting direction 87.

[0493] Since the upper and lower shell parts 80 are each manufactured as injection-molded plastic parts, for example from PP (polypropylene), they possess a certain elasticity that allows their deformability to be utilized during assembly. This is achieved by pressing both shell parts 80 onto the support shaft part 42 in the planned assembly direction 87 under pressure. If the elasticity is too low, the stiffness and deformability can be influenced by selectively reducing the wall thickness at suitable points.

[0494] As shown in Figure 26, further possibilities for a better comparison are shown side by side, such as mounting support bodies 1A with different diameters 50 (see Figure 1) on a support shaft 21. The anti-rotation devices 40 can be used as anchor points for this purpose. The different diameters 50 are accommodated by means of differently designed connecting webs 40A, resulting in a gap 40B between the support shaft section 42 and the support body 1A.

[0495] An additional solution for the described problem in the center of the roller 104 in spreading rollers 100 can also be made possible in a slightly modified form in designs in which straight strip parts 90 are used as the support body 1G, in particular brush strip parts, as will be shown below, where patent attorneys 62

[0496] Particular advantages are given if these strip parts are designed in double rows 90 and are equipped with double rows of wide plug-in elements 2.

[0497] As shown in Figures 27 and 28, a first cross-section of such a support body 1G with a straight strip section 90, preferably made of plastic, is shown. The support body 1G, or the strip section 90 thereof, is equipped with a plurality of spreading elements 2.

[0498] In the present case of the support body 1G, it is a modified rectangular shape which is inserted under slight deformation into the provided receiving form 91 of a corresponding support shaft part 42 (see Figures 29 and 30) and is mounted almost without play due to the deformation stress generated in the process, which contributes to a particularly smooth running of a spreading roller 100.

[0499] The strip section 90, and thus also the support body 1G, is designed in double rows, with the arrangement of the spreading elements 2 being offset from one another, i.e., gap-to-gap in the direction of the central longitudinal axis 6 of the support body 1G. This results in smoother running of the overflowing web 68.

[0500] According to the illustration in Figure 28, different representations are shown of how the tooth elements 22 of the support bodies 1G are interlocked in the dome area 58, and how the differently inclined spreading elements 2 cause different superimposed spreading directions 62A and 62B, as already explained in detail above (see description, for example, regarding Figure 16).

[0501] The support body 1G is designed in such a way that it spreads axially from a roller center 104 to the roller edge of the spreading roller 100.

[0502] As shown in Figures 29 and 30, the previously mentioned support shaft part 42 (see description in Figures 27 and 28) is shown made of an extruded aluminum profile, which can be used alternatively in the spreading roller 100, with the support body 1G being formed in the shape of the straight strip sections 90. A plurality of support bodies 1G are shown here in receiving forms 91 (longitudinal grooves 48).

[0503] of the support shaft part 42, which also provides a suitable roller part 86 for the spreading roller 100.

[0504] According to the illustrations in Figures 31 to 36, a further embodiment of an alternative support body 1G is shown by way of example, the straight strip part 90 of which is provided with a dovetail shape 92 for forming a dovetail joint 92A for connecting with receiving forms 91 (longitudinal grooves 48) of a correspondingly designed support shaft element 42 in accordance with the present invention.

[0505] As can be seen from Figures 35 and 36, the support body 1G and the corresponding support shaft part 42 are joined to form an alternative roller part 86. A designated roller center 104 is located in the coupling area 58.

[0506] As shown in Figure 37, two further embodiments of spreading rollers 100 are shown in direct comparison, wherein the upper spreading roller 100 is manufactured by means of the roller part 86 according to the embodiment from Figure 30, while the lower spreading roller 100 is manufactured by means of the roller part 86 according to the embodiment from Figure 36.

[0507] Each spreading roller 100 is further characterized by lateral bearing elements 42A and end caps 108 (numbered for illustrative purposes only). In operation, each spreading roller 100 rotates with a web of material 68 (see, for example, Figure 15) about its longitudinal axis of rotation 102.

[0508] An outer surface part 110 of the spreading roller 100 can be provided, for example, by means of the support bodies 1G.

[0509] Therefore, by means of all support bodies 1A to 1G, a outer shell surface part 110 of a spreading roller 100 can be designed in a structurally advantageous manner.

[0510] The embodiments shown here are merely examples of the present invention and should therefore not be interpreted as limiting. Alternative Patent Attorneys 64

[0511] Embodiments considered by a person skilled in the art are equally covered by the scope of protection of the present invention.

[0512] Regarding the second part of the figures, it should be noted that all reference marks “nn” to the second part of the figures should be understood as “ll-nn”, both in the figures themselves and in the following description of the second part of the figures:

[0513] Fig. 11-1 shows the fiber bundle support body 1 according to the invention as an injection-molded part. Both ends are smooth. However, they can also be designed so that they can be pushed together against rotation by means of a profile. Inside are the anti-rotation features 7, which are arranged in pairs or groups of four at 180° or 90° respectively. This arrangement – ​​e.g., a 36 mm pitch and four anti-rotation features – allows assembly in the same or opposite directions. Thus, in back-to-back assembly, the structure is rotated by a 36 mm pitch, which is necessary to achieve a uniform and identical structure on both sides. The diameter 31 and the length 32 can be selected almost arbitrarily; the division of the machining lines 4, which in this case is the 36 mm pitch, can be adjusted by appropriate calculations.The processing or occupancy lines 4 are normally arranged axially, but they can also be designed at an angle.

[0514] The toothing 3 is shown as an example of a cone, but it can also be used as any other sliding shape, such as a rectangle.

[0515] Figure 11-1.1 shows two identical fiber bundle support bodies 1, which are nested inside one another. The axial occupancy lines 4 and the tangential occupancy lines 38 are shown on the left fiber bundle support body 1. The intersections of these occupancy lines 4 and 38 represent the possible fiber bundle positions. As will be shown, fiber bundle anchors can be provided at these intersections, but they can also be used only partially. Patent Attorneys 65

[0516] At both ends of the fiber bundle support body 1 is an identically shaped toothed section, which can be joined together in any configuration. A tooth depth of 43 is necessary to create a closed envelope, even when the fiber bundle support bodies 2 are pushed together in such a way that they point in different spreading directions (as is necessary in the center of the roller), thus preventing a V-shaped annular gap. The tooth depth 43 can be calculated using the values ​​of the geometric properties.

[0517] The tooth depth 43 is in the range of 10 to 35 mm for normal fiber bundle support body dimensions.

[0518] The end faces of the toothing can be perpendicular to the axis, but they can also be adapted to the inclination of the fiber bundles, as indicated in Figures 11-1, 11-1.1 and II-2.

[0519] Figure 11-1.2 shows a developed section of the fiber bundle support body 1 according to the invention in the area of ​​the roller center, where the fiber bundle support bodies are mounted back-to-back. The fiber bundles 10 of part 53 project to the right, those of part 54 to the left. The toothing 3 with tooth depth 55 is located in the roller center 18. The fiber bundles 10 project beyond the center 18 into the area of ​​part 54, and the fiber bundles 9 into the area of ​​part 53. Since the fiber bundles 9 and 10 act in opposite directions and are always directly adjacent to each other, their effects cancel each other out. However, their presence is necessary to avoid the undesirable V-shaped annular gap.

[0520] In the central region 55, the contact surfaces of the fiber bundles 2 are oriented in different spreading directions. The crucial point here is that the inclination angles of the fiber bundles must correspond to those of the other fiber bundles 2, as this is the only way to ensure that the deformation is the same as in the rest of the fiber bundles 2 and that the deformation does not lead to a different diameter in this area, which could result in wrinkles and thus waste, since the web is always pulled towards the highest point. Patent Attorneys 66

[0521] The inventive solution for the problem in the center of the rollers in brush spreading rollers is also possible in a slightly modified form in designs where the brush strips are used as fiber bundle support bodies, as will be shown later, with particular advantages if these brush strips are designed in double rows.

[0522] Figure II-2 shows the complete fiber bundle support body 1 with an exemplary fiber bundle arrangement 8. The fiber bundles 2 are arranged along the machining lines 4. The arrangement and distribution of the fiber bundles 2 along the machining lines 4 can be determined arbitrarily and according to process requirements; however, it should be rotationally symmetrical, and the envelope 5 should always be circular. The fiber bundle arrangement 8 also extends onto the tooth surface 3.1 and thus, by pushing the teeth 3 together and the associated overlap of the fiber bundles in the edge region, prevents the formation of the V-shaped annular gap, which would always have a disruptive effect. In Figure II-2, the bundle coverage is 100%.

[0523] Figure II-3 shows the interior of the fiber bundle support body 1. The continuous anti-rotation devices 7 can be seen. They are guided in grooves 22 on the support shaft 6.

[0524] The anti-rotation devices 7 can extend over the entire length, but they can also be interrupted or only attached to the ends of the fiber bundle support body 1. In Figures II-3 to II-5, the bundle coverage is 60%.

[0525] Figure II-4 shows one fiber bundle support body 14 with fiber bundles 9 pointing to the left and two fiber bundle support bodies 13 with fiber bundles 10 pointing to the right. When the fiber bundle support bodies 14 are pushed together according to movement 11, a uniform image 16 results in Figures 11-5.1 to II-5.3. When the fiber bundle support body 13 is moved in the direction of movement 12, the arrangement 15 results in Figure 11-5.1, which normally corresponds to the roller center 18. Here, the arrangement 15 avoids a possible V-ring gap, which is very important. Patent Attorneys 67

[0526] is, and the spreading directions 19 and 20 (Figure II-7) are directed from the roller center 18 to the roller end, which is also the aim of this invention.

[0527] In area 16, the fiber bundle arrangement is such that a fiber bundle 2 is positioned on each processing line 4, while in area 17, only every second processing line 4 is equipped with a fiber bundle 2. The density of the fiber bundle arrangement can therefore be adapted to process-related requirements.

[0528] Figure 11-5.1 shows fiber bundle densities of varying density, e.g.

[0529] A coverage of only 50% is possible (35%). This is quite applicable if the web of material is relatively thick or robust.

[0530] The occupancy density 36 at a value of 66%, the occupancy density 37 at 100%.

[0531] In all cases, an irregularity in the form of a gap is avoided in the center of the roller 15 by sufficient coverage.

[0532] Since the system always uses the identical fiber bundle support body 1, it is also possible to combine differently populated fiber bundle support bodies.

[0533] Figure II-5.2 shows a coverage density of 100% and a fiber bundle arrangement in which all fiber bundles lie axially on a coverage line.

[0534] FIGURE II-5.3 shows a layout in which the fiber rows 51 and 52 are arranged offset from each other, which is also a common design.

[0535] Figure II-6 shows an example of a possible solution for a support roller 6 onto which the fiber bundle support bodies 1, 13, and 14 are mounted. In this case, the support roller 6 is equipped with four grooves 22. These grooves form the guides for the anti-rotation device 7. Four grooves 22 are provided, extending over the entire length of the support roller 6. The support roller 6 is connected at both ends to a support shaft stub 21, which is connected via the (only schematically shown) patent holders 68.

[0536] The bearing 23 is permanently connected to a fixed frame or similar structure, thus enabling the free movement of the entire stretching roller 24, as shown in

[0537] Figure II-7 illustrates this. The web 25 runs over the freely rotatable spreading roller 24, which is normally driven by the web 25. With a symmetrical fiber bundle arrangement, the spreading roller 24 can be operated in both directions of rotation. The solution for the roller center 18 is essential. In the roller center 18, the fiber bundle support elements 1 13 and 14 are arranged such that their spreading direction 19 and 20 is directed from the roller center 18 to the outer end of the roller. The V-shaped annular gap in the roller center, which occurs in brush spreading rollers with inclined fiber bundles, is successfully avoided in the present invention by ensuring that the fiber bundles 13 and 14 are positioned so closely together by being pushed together and the resulting overlap that the spreading effect of the fiber bundles 19.1 and 20.1 begins directly in the roller center area 18.It is important that all fiber bundles 2 have the same direction of action, namely parallel to the axis, and furthermore, that all fiber bundles 2 have the same angle of inclination, so that under pressure from the web, all fiber bundles experience the same deformation, resulting in a uniform change in diameter for all fiber bundles. This is particularly important for smooth running when the web is not elastic, e.g., in the case of thin metal foils.

[0538] Only in the center of the roller 18 are the fiber bundle support bodies 1 mounted "back-to-back". All other fiber bundle support bodies 1 are connected in the same direction, thus resulting in a uniform and consistent surface structure, the distribution of which within the basic arrangement of the processing lines 4 can be determined according to the requirements of the application parameters.

[0539] Another solution for spreading rollers that are assembled only from parts that are all identical in design is to use a half-shell instead of the tubular fiber bundle support body 1, which is designed according to the same criteria as the fiber bundle support body 1 and which is based on the patent attorneys 69

[0540] The assembly of the two half-shells is represented in the same way as the fiber bundle support body 1.

[0541] The advantage of this variant lies in the reduced design effort, simpler assembly and lower costs for small production runs.

[0542] Figure II-8 schematically shows the cross-section with the upper shell 26 and the lower shell 27, which are identical in construction and represent the same component, as well as the principle of joining them using the toothing 28. This toothing is provided on both sides with a bore 29, with which its position is fixed in the assembled state with a pin 30 (Figure II-9).

[0543] Figure II-9 shows the upper shell 26 mounted on the support roller 6. The upper shell 26 is held on both sides of the support roller 6 by the mounting extension 28, which is inserted into the guide grooves 7. The connection to the lower shell 27 via the extension is secured by the safety pin 30. The required bore 29 is positioned in the area of ​​the guide groove 7 and the mounting extension 28 such that the fiber bundles 2 can be inserted on the outside without restriction. For assembly, the upper shell 26 and lower shell 27 can be pre-assembled according to

[0544] Figure 11-10 are pushed onto the support roller 6. Although they are positively connected gap-to-gap by mounting, the safety pin 30 is intended to secure the connection.

[0545] Another assembly method is shown in Figure 11-11. Since the upper shell 26 and lower shell 27 are manufactured as injection-molded parts from plastic, e.g., PP, they possess a certain elasticity that allows their deformability to be utilized during assembly. Both shells are pressed onto the fiber bundle support body 6 in the assembly direction 33 under pressure, according to the planned assembly. If the elasticity is too low, the stiffness and deformability can be influenced by selectively reducing the wall thickness at suitable points.

[0546] Figures 11-12 show the two structurally identical half-shells 39. They are designed like the fiber bundle support body 1 and also have the same dimensions, which offers advantages. Patent attorneys 70

[0547] during the programming of the bundling machines. They are designed so that they can be easily mounted with virtually no play using the fitting elements 40 and 41. The bores 45 for the safety pins are visible in the fitting points.

[0548] Figures 11-13 show the double half-shell ready for assembly with the fiber bundle arrangement at 100% coverage. The separation joint 42 indicates the dividing line.

[0549] Figures 11-14 illustrate the possibility of mounting different fiber bundle support bodies 1 on a support shaft 21. The anti-rotation devices 7 can be used as anchor points for this purpose. The connecting webs 60 allow for adjustments to different diameters of the fiber bundle support bodies 1.

[0550] Figures 11-15 show an extruded aluminum profile 61 used in brush spreading rollers whose fiber bundle support bodies 58 are formed in the form of strips. These are spreading rollers in which the spreading effect is generated by so-called brush strips 67. In these brush strips 67, the fiber bundles 65, 66 are inserted into extruded receiving strips 58. These brush strips 67 are installed in extruded aluminum profiles 61 with the corresponding receiving guides 59.

[0551] Figures 11-16 show the cross-section of such a support strip 58, which is usually made of plastic. In this case, it is a modified rectangular shape that is inserted into the provided receiving form 59 with slight deformation and is mounted almost without play due to the deformation stress generated, which contributes to smooth running. The brush strip 67 is designed in two rows, with the fiber bundle arrangement staggered, i.e., gap-to-gap. Figures 11-17. This results in smoother running of the overflowing web. The brush strips 65 and 66 are designed to spread out from the center of the roller towards the edge of the roller.

[0552] Another solution involves installing the double-row brush strips in a dovetail guide. Figure 11-18. The support roller profile 72 is easy to manufacture as an aluminum profile. The advantage of this design is that the fiber bundles 2 are quite close together, so that the fiber bundle spacing is small. Patent Attorneys 71

[0553] as shown in Figure 11-19. The roller center 18 also fulfills the inventive objective by avoiding a V-shaped central gap, which is also shown in detail in Figure 11-21. The design of the roller center is determined by the parting line 56. It ensures that the fiber bundles 68 and 69 neutralize the spreading forces precisely in the roller center and thus avoid the V-shaped central gap.

[0554] The double-row brush strip can be cut off in the center of the roller by a suitable cutting cut 56, as shown in Figures 11-18, such that the anchoring points of the fiber bundles 68 and 69 project behind the roller center into the strip 65 and 66, but the contact area of ​​the fiber bundles 68 and 69 lies on the roller center 63. Thus, only the spreading forces of these fiber bundles 68 and 69 cancel each other out, and the V-shaped annular gap is avoided. Therefore, the objective of the invention is also achieved in this case of the brush strip design.

[0555] While this concludes the description of the figures for the second part, further possible aspects of the invention in the form of feature combinations are listed below. These are to be understood as advantageous both alternatively and cumulatively. In the following description of feature combinations, the reference numerals given are to be understood as referring to the first part of the figures, i.e., to Figures 1 to 37. This does not mean, however, that the feature combinations can only be read as referring to the first part of the figures. Rather, they can also be read as referring to the second part of the figures; the only difference is that no reference numerals are explicitly written out in the feature combinations.
