Description
[0001] Manufacturing method and manufacturing device for producing closure tabs for a diaper and diaper with closure tabs
[0002] Background of the invention
[0003] The invention relates to a manufacturing method for producing closure tabs for a diaper. Furthermore, the invention relates to a manufacturing device for producing closure tabs. Furthermore, the invention relates to a diaper with closure tabs.
[0004] Various types of diapers, particularly disposable or single-use diapers, are known from the prior art. So-called "trouser-type" diapers or pull-on diapers are designed in the form of pants-like, closed pieces and can be put on by a human wearer like pants, with the legs being pulled through the diaper. This type of diaper typically has several intended tear points that allow the diaper to be torn open to remove it. This allows the wearer to hygienically remove the used diaper without the legs coming into contact with the contaminated diaper. Another type of diaper uses closure tabs to close the diaper.Typically, this type of diaper is placed around the crotch of a human wearer with the closure flaps unfastened and then secured in the pelvic area by the closure flaps, ensuring a secure fit. When closed, the closure flaps typically form a hook-and-loop fastener that can be released to remove the diaper. Once removed, the hook-and-loop fastener can be reused to secure the rolled-up diaper, thus preventing environmental contamination from the used diaper.
[0005] Diapers and methods for producing closure tabs are known from EP 1 941 853 B1 and EP 2 641 574 B1. The described methods are optimized for maximum material utilization, which limits production flexibility to a few diaper types and sizes.
[0006] US Pat. No. 6,730,069 B2 discloses a manufacturing method for producing mechanical fasteners, in which molten polymer is poured into recesses in a carrier tape to subsequently form hook-and-loop fasteners from the molten polymer. However, the fasteners thus formed have a reduced material thickness of the carrier layer in the area of the hook-and-loop fasteners, which reduces their strength.
[0007] Furthermore, the known processes are technically challenging to implement and the manufacturing equipment used is prone to errors, which leads to downtimes in production.
[0008] The invention is therefore based on the object of providing a manufacturing method with which various types of closure tabs can be produced simply, quickly, and robustly at low cost. Furthermore, the invention is based on the object of providing a manufacturing device and a diaper with a closure tab.
[0009] This object is achieved according to the invention by a manufacturing method having the features of patent claim 1. The object is also achieved by a manufacturing device having the features of patent claim 5. Furthermore, the object is achieved by a diaper according to patent claim 9. The subclaims describe preferred embodiments of the invention.
[0010] According to the invention, a manufacturing method is provided.
[0011] The manufacturing process is designed to produce a closure flap. The closure flap is typically suitable for closing a diaper as described above and below.
[0012] The manufacturing process includes at least the following process steps:
[0013] A first method step a) involves providing a hook tape and at least one textile or textile-like backing layer tape. The hook tape and the at least one backing layer tape are preferably provided in rolled form. This simplifies further processing.
[0014] Here and below, the term "hook tape" refers to a hook-and-loop fastener with a plurality of hooks and / or mushrooms. The hook tape is typically produced in a separate process prior to the manufacturing process. The hook tape is preferably made of one piece and / or a single material.
[0015] The hook-and-loop fastener tape preferably has a hook width of at least 2 millimeters, particularly preferably at least 5 millimeters. The hook-and-loop fastener tape can preferably have a hook width of at most 20 millimeters, particularly preferably at most 10 millimeters. In a particular embodiment, the hook tape has between 50 and 5,000 hooks per square centimeter. The hooks are typically rectangular, hexagonal, and / or randomly arranged. The aforementioned properties of the hook tape, individually and in combination, have proven particularly suitable for forming a hook-and-loop fastener on a diaper.
[0016] A carrier layer tape is typically understood as a tape with minimal material thickness, limited width, and extended length. In other words, the carrier layer tape can essentially be understood as a two-dimensional sheet.
[0017] The textile carrier layer tape can be understood here and below as a tape made of a spinnable, woven, and / or knittable material. Preferably, the textile carrier layer tape comprises nonwoven fabric and / or is formed from nonwoven fabric.
[0018] A textile-like carrier layer tape can be understood here and below as a tape made of a non-textile material with properties similar to those of a textile tape. The textile-like carrier layer tape is preferably in the form of a film. Further preferably, the textile-like tape comprises or is formed from a thermoplastic, particularly preferably a polyolefin, in particular a polypropylene.
[0019] A further method step b) provides for the, in particular planar, application of the hook tape and the carrier layer tape. In other words, surface contact is created between the hook tape and the carrier layer tape. The surface contact is preferably created across the entire width of the hook tape, thereby ensuring a wave-free fit against the carrier layer tape. In addition, the hook tape is fastened to the carrier layer tape at least in sections. Sectional fastening can be understood as a punctual or area-limited fastening. In other words, with section-by-section fastening, the hook tape is not fastened to the carrier layer tape over its entire surface. This can simplify the subsequent method steps. Fastening can prevent relative movement between the hook tape and the carrier layer tape.
[0020] To attach the hook tape to the carrier layer tape, a binding agent, in particular an adhesive, is preferably introduced into the contact area between the hook tape and the carrier layer tape. The binding agent is particularly preferably introduced immediately before the hook tape and the carrier layer tape are placed together, thereby ensuring a particularly secure attachment and allowing the use of a particularly rapidly setting binding agent. Alternatively or additionally, the hook tape can be welded to the carrier layer tape. Welding enables particularly precise and rapid attachment of the hook tape. Welding also enables the hook tape to be attached to the carrier layer tape in the placed-together state.
[0021] Alternatively or additionally, for section-by-section fastening, the hook tape and / or the carrier layer tape can already have an adhesive surface in the provided state. This allows the hook tape to be fixed and / or secured over the entire surface of the carrier layer tape.
[0022] Preferably, a rubber-based and / or polyolefin-based binder is used for bonding. This ensures good skin compatibility.
[0023] Furthermore, welding is preferably carried out using ultrasonic or high-frequency welding. This allows the fastening to be carried out without damaging the hook tape and / or the backing layer tape.
[0024] In a further method step c), the removal of at least one, preferably several, hook sections from the hook band is provided. The removal preferably occurs by dissolving the mechanical connection or the material bond between the hook band and the respective hook section. Typically, the removal occurs by cutting through the hook band along a designated edge of the hook section to be formed.
[0025] According to the invention, a separation can be understood as a weakening of the material strength between the hook band and the hook section to be formed, wherein the holding forces between the hook band and the hook section are subsequently lower than the holding forces between the carrier layer band and the hook section. By fastening the hook band in the region of the hook sections to be separated, the holding forces between the hook section and the carrier layer band can be greatly increased, whereby a smaller weakening of the material strength can also lead to the separation of the hook sections. Weakening the material strength advantageously prevents damage to the carrier layer band during the separation of the hook sections from the hook band applied to the carrier layer band.
[0026] A method step d) is also provided, in which a closure flap strip is produced by detaching the hook strip from the at least one carrier layer strip. Upon detachment of the hook strip from the carrier layer strip, the at least one severed hook section remains on the carrier layer strip. In other words, the hook strip previously applied to the carrier layer strip is detached from it again. Since the holding forces between the hook section and the carrier layer strip exceed the holding forces between the hook section and the hook strip, the hook section remains on the carrier layer strip during the detachment.
[0027] The resulting closure tab strip thus comprises at least one carrier layer strip and at least one hook section detached from the hook strip, the hook section being attached to the carrier layer strip. The closure tab strip preferably comprises several, in particular a plurality of, hook sections arranged spaced apart from one another on the carrier layer strip.
[0028] In summary, the manufacturing method according to the invention provides for attaching hook sections of a hook band to a carrier layer band, wherein the hook sections are formed during or after the hook band and the carrier layer band are applied to one another. The described method thus proposes the production of a closure flap band using simple means and process steps, thereby keeping the robustness of the manufacturing process and the provision and maintenance costs low. Furthermore, the method is particularly suitable for implementation as a so-called endless process with continuous feeding of the hook band and the carrier layer band for further processing, which can increase the production speed and further reduce production costs.
[0029] In a preferred embodiment of the manufacturing process, in process step a), an additional carrier layer tape is provided, and in process step c), the carrier layer tape is attached to the additional carrier layer tape. In other words, the manufacturing process can be carried out by providing at least two carrier layer tapes. This allows the manufacturing process to be particularly easily adapted to different dimensions of the closure tabs to be produced using the same hook tape and the same carrier layer tape. Furthermore, the strength of the closure tabs can be increased by a multi-layer design of the closure tab tape.
[0030] The additional carrier layer tape is preferably attached to the carrier layer tape by introducing a binding agent, in particular an adhesive, into the contact area between the carrier layer tape and the additional carrier layer tape. Preferably, the additional carrier layer tape is attached to the carrier layer tape over its entire surface. The binding agent is preferably introduced immediately before the carrier layer tape is placed against the additional carrier layer tape. Alternatively or additionally, it can be provided that the carrier layer tape and / or the additional carrier layer tape have an adhesive surface designed to attach the additional carrier layer tape to the carrier layer tape.
[0031] In a preferred embodiment, the manufacturing method comprises the additional method step e), which provides for the creation of closure tabs by forming closure tab edges by sectionally cutting the closure tab strip. In other words, the closure tab strip is separated or separated into closure tabs. The cutting preferably takes place by cutting into or through the closure tab strip. The closure tab edge is formed at a predetermined minimum distance from the at least one hook section. By having a hook section set back from the closure tab edge, a hard and / or sharp-edged closure tab edge can be prevented. This can increase the wearing comfort of the diaper using the closure tabs and reduce the risk of injury, for example cuts, when putting on and taking off the diaper.
[0032] In a particular embodiment, the minimum distance is 1 or more millimeters, preferably 2 or more millimeters, particularly preferably 3 or more millimeters.
[0033] Particularly preferred is an embodiment of the manufacturing process in which process step b) and process step c) are performed simultaneously. In other words, the hook tape, the carrier layer tape, and optionally the additional carrier layer tape are pressed together, or simultaneously, with the removal of the hook sections from the hook tape. This allows the process duration and the manufacturing speed to be increased, thereby increasing productivity and keeping costs low. The object underlying the invention is also achieved by a manufacturing device.
[0034] The manufacturing device is designed to produce a closure tab, in particular for a diaper. The manufacturing device is particularly configured to carry out the manufacturing method described above and below.
[0035] The manufacturing device comprises a supply unit. The supply unit is designed to supply a hook tape and at least one carrier layer tape. Preferably, the supply unit comprises a magazine, in particular a roll magazine. The roll magazine can comprise rolls for storing the tapes, in particular a first supply roll for storing the hook tape and a second supply roll for storing the carrier layer tape.
[0036] The manufacturing device also has a joining unit for joining the hook band to the carrier layer strip. The joining unit is typically designed for applying the hook band to the carrier layer strip. Furthermore, the joining unit is designed for separating at least one hook section, in particular a plurality of hook sections, from the hook band.
[0037] The production device also has a removal unit. The removal unit is designed to separately receive the hook tape and the closure tab tape. Preferably, the removal unit has a magazine, in particular a roll magazine with multiple rolls for separately receiving the tapes. Further preferably, the removal unit has a first removal roller for receiving the hook tape and a second removal roller for receiving the closure tab tape. The joining unit preferably has a drive unit. Preferably, the drive unit is designed to drive the supply unit, the joining unit, and / or the removal unit.
[0038] During operation of the production device, the hook tape and the carrier layer tape are typically conveyed from the supply unit, in particular by unwinding the supply rolls, into the joining unit. Within the joining unit, the hook tape and the carrier layer tape are placed against one another, in particular fastened to one another. During or after this process, the hook sections are cut out of the hook tape. The hook tape is then deflected relative to the carrier layer tape, causing the hook tape to be released from the carrier layer tape within the joining unit, thus creating the closure flap tape. The hook tape can then be received separately from the closure flap tape in the removal unit.Preferably, the hook band is detached from the carrier layer band by appropriately positioning the removal device relative to the joining unit, so that the removal by the removal device results in a spatial spacing of the hook band from the carrier layer band. Furthermore, it can be provided that the hook band is spatially spaced from the carrier layer band by the arrangement of deflection devices, in particular deflection rollers.
[0039] In summary, the invention proposes a manufacturing device with a particularly simple design. This allows for low setup and maintenance costs. Furthermore, the manufacturing device enables a particularly reliable production process.
[0040] In a preferred embodiment of the production device, the joining unit comprises roller tools between which the hook tape and the carrier layer tape are guided. A particularly high production speed can be achieved using roller tools. The roller tools are designed and arranged relative to one another for placing, in particular pressing, the hook tape and for separating hook sections. In particular, it can be provided that the tapes are pressed together by appropriately spacing the roller tools from one another while forcing the tapes to be guided. Furthermore, it can be provided that a roller tool is designed to impart a rotary movement for cutting into and / or cutting through the hook tape at the edge of the hook sections to be formed. Roller tools represent a particularly reliable and cost-effective processing method.
[0041] A further preferred development of the manufacturing device is one in which the joining unit comprises at least one tool roll and at least one stop roll. The at least one tool roll is typically designed for applying, in particular pressing, the hook band onto the carrier layer band. Preferably, one tool roll, in particular the same tool roll, is designed for separating the hook sections from the hook band. A tool roll designed for applying the bands and separating the hook sections is particularly suitable for simultaneously carrying out method steps b) and c) of the manufacturing method described above and below. Typically, the stop roll is designed to form a stop, through which the processing forces of the tool roll acting on the hook band and the carrier layer band are diverted.This ensures that the process steps are carried out reliably.
[0042] A further preferred embodiment of the production device is one in which the tool roll has at least one punching web, the punching web having a web height that protrudes radially beyond a roller base body of the tool roll. The web height preferably corresponds to a strip thickness of the hook strip. By forming a punching web on the tool roll, the hook sections can be cut out of the hook strip precisely and quickly. The tool roll preferably has a plurality of punching webs. Typically, the punching webs form a web contour, in particular a circumferential one, which corresponds in shape and design to the hook section to be cut out. Cutting out can then take place by rolling the punching web on the hook strip, the punching web causing the hook strip to be cut out or weakened in the area of action.
[0043] The object underlying the invention is further achieved by a diaper.
[0044] The diaper is designed to be placed on a human wearer. The diaper includes a diaper body typically configured to receive, absorb, and / or retain media discharged from the wearer's body.
[0045] The diaper base body is also typically shaped or configured for application in the crotch area of the wearer. The diaper base body has at least one, in particular two, adhesive sections and at least one, in particular two, closure tabs. The at least one, in particular all, closure tabs are preferably configured for closing the diaper in a pelvic area and / or in a hip area of the wearer.
[0046] The at least one closure flap is manufactured in particular according to the manufacturing process described above and below. This makes it possible to provide a cost-effective diaper with a high level of comfort.
[0047] The closure flap has at least one textile or textile-like backing layer. The backing layer is typically produced by shredding or separating the backing layer strip of the closure flap strip. The backing layer is permanently attached to the diaper body. Typically, the backing layer is glued to the diaper body.
[0048] The backing layer has a constant backing layer thickness. In other words, the backing layer is formed with a constant thickness and preferably has no tapered areas. This ensures uniform strength of the closure flap. Furthermore, the closure flap has at least one hook section for a releasable hook-and-loop connection to the adhesive section of the diaper body. By forming closure flaps with at least one hook section, the hook-and-loop connection can be achieved particularly simply.
[0049] The at least one hook section of the closure flap has a minimum distance from the closure flap edges of the carrier layer all the way around. In other words, the hook sections are set back from the closure flap edge. This prevents the formation of a hard and / or sharp-edged closure flap edge, thereby reducing the risk of injury when putting on and / or taking off the diaper and increasing the diaper's comfort.
[0050] A preferred embodiment of the diaper is one in which the closure flap has at least two hook sections for a releasable hook-and-loop connection to the adhesive section of the diaper body. By forming closure flaps with two or more hook sections, the holding force of the hook-and-loop connection can be adjusted particularly flexibly. Furthermore, by forming two or more hook sections, the closure flap can be made more elastic, thereby improving the handling of the closure flap.
[0051] Typically, each of the hook sections has a minimum distance from the edges of the fastener tabs on the carrier layer. This can further prevent the formation of a hard and / or sharp-edged fastener tab edge.
[0052] In a preferred embodiment of the diaper, the closure flap has an additional backing layer. An additional backing layer can adapt the dimensions of the closure flap to diaper-specific specifications without having to modify the backing layer and the hook sections. This allows the closure flap to be adapted particularly easily. Furthermore, an additional backing layer can increase the strength of the closure flap in an overlap area with the backing layer, making the closure flap more durable.
[0053] The additional carrier layer protrudes at least partially beyond the at least one carrier layer. The additional carrier layer protrudes at least on one side beyond the carrier layer. Typically, the additional carrier layer, in particular the section of the additional carrier layer protruding beyond the carrier layer, is designed for permanently attaching the closure tab to the diaper body. In other words, the closure tab forms a fastening section.
[0054] Preferably, the additional backing layer protrudes beyond the backing layer at least on both sides of the hook sections. Furthermore, the additional backing layer preferably forms a fastening section facing the diaper base body and an actuating section facing away from the diaper base body. The actuating section and the fastening section are preferably formed on opposite sides of the hook sections. An actuating section simplifies the handling of the closure tab when forming and releasing the hook-and-loop connection.
[0055] A preferred embodiment of the diaper is one in which the at least one carrier layer and the further carrier layer of the closure flap jointly form at least one, in particular at least two, sections of the closure flap edges. This allows for a stiffer closure flap edge while avoiding a hard or sharp-edged design.
[0056] In a preferred embodiment of the diaper, at least one of the support layers of the closure flap is rectangular, trapezoidal, or parabolic. By designing the closure flap accordingly, it can be easily adapted to different types of diapers. Furthermore, the handling of the closure flap can be improved. Also preferred is an embodiment of the diaper in which the closure flap has at least three hook sections arranged next to one another in a line. Three or more hook sections enable a particularly secure hook and loop connection, in particular when the hook areas do not completely overlap an adhesive area of the diaper. This can ensure that at least one hook section creates a hook and loop connection with the adhesive section of the diaper.
[0057] A preferred embodiment of the diaper provides for the hook sections of the closure flap to be of identical design. This allows for a particularly even distribution of the holding forces of the hook-and-loop fastener across the individual hook sections.
[0058] In a preferred embodiment of the diaper, the hook sections of the closure flap are rectangular or circular, particularly elliptical, in shape. A rectangular or circular design of the hook sections simplifies the manufacture of the closure flap and reduces manufacturing costs. Furthermore, a rectangular or circular design of the hook sections has proven particularly suitable for creating a secure hook-and-loop connection.
[0059] Furthermore, an embodiment of the diaper is preferred in which the closure tab is designed, when the diaper is put on the wearer, for hook-and-loop connecting the at least one hook section to the adhesive section directly on a hip of the wearer. The diaper preferably has two or more closure tabs. In other words, the closure tab, in particular the closure tabs, are designed for use on a so-called pull-on diaper or diaper pants. The manufacturing method described above and below has proven to be particularly suitable for producing closure tabs for diapers of this type. Furthermore, a development of the diaper is preferred in which the at least one hook section and the at least one adhesive section extend transversely or perpendicularly to a closure direction of the diaper. In particular when using such closure tabs, orHook sections on pull-on diapers with side closure can achieve a secure hook and loop connection in conjunction with easy manual release of the hook and loop connection through appropriate arrangement of the hook sections and adhesive sections.
[0060] Further advantages of the invention will become apparent from the description and the drawings. Likewise, the above-mentioned and further-described features can be used individually or in combination in any desired manner. The embodiments shown and described are not intended to be exhaustive, but rather are exemplary in nature for describing the invention.

[0068] Fig. 8 shows a perspective view of a second embodiment of a diaper with a closure flap that can be closed directly on a wearer's hip according to a third embodiment.
[0069] Fig. 1 shows a schematic representation of a manufacturing method 10 according to the invention. The manufacturing method 10 is intended for producing a closure tab 12 (see Figs. 6-8) for a diaper 14 (see Figs. 7, 8).
[0070] The manufacturing process 10 is explained below with reference to the other figures of the drawing.
[0071] A first method step 16 of the manufacturing method 10 provides for the provision of a hook tape 18 (see Figs. 2-4) and at least one carrier layer tape 20 (see Figs. 2-4). The hook tape 18 is typically designed as a hook-and-loop fastener tape having hooks (not shown) and / or mushrooms (not shown). The carrier layer tape 20 is typically textile or textile-like, preferably as a nonwoven.
[0072] The hook strip 18 and the carrier layer strip 20 are preferably designed to be unrolled and rewound. This allows the hook strip 18 and the carrier layer strip 20 to be provided in roll form, whereby the manufacturing method 10 can be carried out particularly effectively. Preferably, the hook strip 18 and the carrier layer strip 20 are provided on separate rolls. This simplifies the preparation process for the joining method 10.
[0073] A subsequent process step 22 of the manufacturing process 10 provides for the juxtaposition of the hook band 18 and the carrier layer band 20. Juxtaposition can be understood as the formation of surface contact between the hook band 18 and the carrier layer band 20. Preferably, the hook band 18 is pressed against the carrier layer band 20. This ensures a particularly flat contact. Furthermore, process-related unevenness in the hook band 18 and / or the carrier layer band 20 can be smoothed by pressing, thereby simplifying the further processing of the juxtaposed bands.
[0074] Typically, the hook tape 18 is attached to the carrier layer tape 20 at least in sections during the assembly process. For this purpose, a binding agent (not shown), in particular an adhesive, can be introduced into a contact area 24 (see Fig. 4) between the hook tape 18 and the carrier tape 20. Alternatively or additionally, the hook tape 18 can be welded to the carrier layer tape 20 in sections.
[0075] A further method step 26 of the manufacturing method 10 provides for the removal of at least one hook section 28 (see Figs. 2-8) from the hook strip 18. Typically, in method step 26, several, in particular a plurality of, hook sections 28 are removed from the hook strip 18. In other words, method step 26 can be repeated several times or many times.
[0076] A separation can be understood as a severing of the material connection between the hook section 28 to be separated and the remaining hook band 18. A separation can also occur by weakening the material connection if, as a result of the weakening, the holding forces between the carrier layer band 20 and the hook band 18 exceed the holding forces between the hook section 28 to be separated and the remaining hook band 18. Preferably, the hook band 18 is fastened to the carrier layer band 20, preferably by introducing a binding agent or welding, only in the contact area 24 between a hook section 28 to be separated and the carrier layer band 20. As a result, the holding forces between the hook section 28 to be separated and the
[0077] Carrier layer tape 20 can be increased compared to the remaining hook tape 18.
[0078] Removal is preferably carried out mechanically by cutting or
[0079] Cutting and / or punching the hook tape 18.
[0080] According to the invention, the at least one hook section 28 is separated from the hook tape 18 without damaging the carrier layer tape 20. This allows further processing of the tapes placed against one another without the risk of a tape tear.
[0081] According to the invention, a method step 30 is also provided in which a closure tab band 32 (see Figs. 2, 3, 5) is produced by detaching the hook band 18 from the at least one carrier layer band 20. During the detachment of the hook band 18, the at least one severed hook section 28 remains on the carrier layer band 20 and, together with the carrier layer band 20, forms the closure tab band 32.
[0082] If the hook band 18 is attached to the carrier layer band 20, the hook band 18 is preferably released from the carrier layer band 20 before the attachment develops its full holding force, for example, before a binding agent and / or a weld seam hardens. Alternatively, it can be provided that the attachment takes place only in the contact area of the at least one hook section 28 to be removed. This allows for release to be performed with the holding force fully developed, thereby increasing the process reliability of the manufacturing method 10.
[0083] In a particular embodiment of the manufacturing method 10, it is provided that in method step 16, a further carrier layer strip 34 (see Figs. 3, 4) is provided. The manufacturing method 10 can further provide, in method step 22, that the carrier layer strip 20 is attached to the further carrier layer strip 34. The carrier layer strip 20 is preferably attached to the further carrier layer strip 34 by introducing a binding agent (not shown). Typically, a surface contact between the carrier layer strip 20 and the further carrier layer strip 34 is formed by pressing. A further carrier layer strip 34 increases the strength of the closure tab strip 32 and thus the strength of the closure tabs 12 to be produced.
[0084] In a particularly preferred embodiment, the manufacturing method 10 comprises a method step 36 that provides for the production of closure tabs 12 by forming closure tab edges 38 (see Figs. 6-8) by sectionally dividing the closure tab strip 32. The dividing is preferably carried out mechanically by cutting and / or punching the closure tab strip 32.
[0085] The production of the closure tabs 12 can follow directly on from the production of the closure tab strip 32. Typically, the cutting is carried out by means of a downstream manufacturing process, whereby a preferably rolled-up closure tab strip 32 is provided.
[0086] In a particularly preferred embodiment of the manufacturing method 10, the method steps 22, 26 are performed simultaneously. In other words, the carrier layer strips 20, 34 and the hook strip 18 are placed together and the hook sections 28 are separated from the hook strip 18 simultaneously. This allows the manufacturing method 10 to be carried out particularly robustly with a simple design of a manufacturing device 40 (see Figs. 2, 3).
[0087] Fig. 2 shows a manufacturing device 40 suitable for producing a closure flap 12 (see Figs. 6-8). The manufacturing device 40 is typically configured to carry out the manufacturing method 10 (see Fig. 1).
[0088] The manufacturing device 40 has a supply unit 42 for
[0089] Providing a hook tape 18 and a carrier layer tape 20. The provision unit 42 can be designed, for example, in the form of a roll magazine (not shown in detail). As shown, the provision unit 42 can have a first supply roll 44 for holding a rolled-up hook tape 18 and a second supply roll 46 for holding a rolled-up carrier layer tape 20. Typically, the supply rolls 44, 46 are designed to hold several hundred meters of tape. By rotating the supply rolls 44, 46, the hook tape 18 or carrier layer tape 20 is unrolled and provided to the manufacturing process 10.
[0090] The manufacturing device 40 also has a joining unit 48. The joining unit 48 is designed to apply the hook band 18 to the carrier layer band 20. As shown, the joining unit 48 can comprise roller tools 50—here, a tool roller 52 and a stop roller 54—between which the hook band 18 and the carrier layer band 20 are guided.
[0091] The radial tool roller spacing 56 (see Fig. 4) between the tool roller 52 and the stop roller 54 preferably corresponds to the total material thickness 62 (see Fig. 4) resulting from the hook band thickness 58 (see Fig. 4) of the hook band 18 and the carrier layer band thickness 60 (see Fig. 4) of the carrier layer band 20. In a particularly preferred embodiment, the radial tool roller spacing 56 is slightly smaller than the total material thickness 62, which can cause the hook band 18 to be pressed against the carrier layer band 20.
[0092] The joining unit 48 is also designed to separate the hook sections 28 from the hook strip 18. As shown, the tool roller 52 of the joining unit 48 can be designed to separate—here, punch out—the hook sections 28 from the remaining hook strip 18.
[0093] Furthermore, the production device 40 comprises a removal unit 64. The removal unit 64 is designed to separately receive the hook tape 18 and the closure tab tape 32. The removal unit 64 can have a roll magazine (not shown in detail). As shown, the removal unit 64 has a first removal roller 66 for receiving the hook tape 18 and a second removal roller 68 for receiving the closure tab tape 32. Typically, the removal rollers 66, 68 are designed to roll up the respective tape.
[0094] To operate the production device 40, it is typically provided that the hook tape 18 and the carrier layer tape 20 are partially unwound from the rolled-up state of the respective supply roll 44, 46, guided between the work rolls 50 of the joining unit 48 and fastened to the respective removal roll 66, 68.
[0095] Subsequently, one or more of the rollers 44, 46, 52, 54, 66, 68 can be set into a rotational movement 70. Preferably, one of the rollers 44, 46, 52, 54, 66, 68, particularly preferably the rollers 50 of the joining unit 48 and / or the rollers 66, 68 of the removal unit 64, comprises a roller drive (not shown in detail). The non-driven rollers can be forced to rotate by the arrangement of the hook band 18 and the carrier layer band 20.
[0096] During operation of the production device 40, the hook tape 18 and the carrier layer tape 20 are continuously unwound from the respective supply roll 44, 46 in the feed directions 72 of the production device 40, placed against one another, in particular pressed against one another, in the joining unit 48, the hook sections 48 are separated from the hook tape 18, the hook tape 18 is detached or lifted from the carrier layer tape 20, and then wound onto the respective removal roll 66, 68. The resulting closure tab tape 32 can then be further processed to produce closure tabs 12. This enables the particularly fast, robust, and cost-effective production of closure tabs 12 with a high level of comfort.
[0097] Fig. 3 shows a particular embodiment of the manufacturing device 40. As shown, the manufacturing device 40 comprises, in addition to the first supply roll 44 and the second supply roll 46, a third supply roll 74 for holding the additional carrier layer strip 34. This enables the implementation of the manufacturing method 10 according to the invention (see Fig. 1) while providing the additional carrier layer strip 34.
[0098] The manufacturing method 10 can be carried out using the additional carrier layer strip 34 essentially analogously to the previously described process, wherein a plurality of strips, namely the hook strip 18, the carrier layer strip 20, and the additional carrier layer strip 34, are placed together in the joining unit 48. In other words, the manufacturing device 40 is designed for placing, preferably pressing, at least three strips together. The closure tab strip 32 comprises, as shown, the carrier layer strip 20, the additional carrier layer strip 34, and the hook sections 28.
[0099] By using an additional carrier layer tape 34, the closure tab tape 32 can be varied in a closure tab tape width 76 (see Fig. 4), and the overall material thickness 62 can be increased, particularly in the area of the hook portions 28. This allows the closure tab 12 to be adapted for use on a specific type of diaper 14 (see Figs. 7, 8). Furthermore, the strength of the closure tabs 12 made from the closure tab tape 32 can be increased.
[0100] The removal unit 64 can remain unchanged, thereby keeping the costs for the provision and conversion of the production device 40 low and enabling easy adaptation to different designs of the closure tab band 32.
[0101] Fig. 4 shows a schematic representation of an exemplary joining unit 48 with a hook band 18 arranged therebetween, a carrier layer band 20 and a further carrier layer band 34. As shown, the joining unit 48 is designed for placing the bands together and for separating the hook sections 28 from the hook band 18.
[0102] As shown, the joining unit 48 has two tool rollers 50—here, the tool roller 52 and the stop roller 54—which are each mounted, in particular driven, for rotation about a rotational axis 78. The tool rollers 50 are designed to dissipate the forces generated during the joining or placement of the strips.
[0103] The stop roller 54 preferably has a constant roller radius 80. This allows the manufacturing costs for the stop roller 54 to be kept low.
[0104] The tool roller 52 can have a roller base body 82 with a base body radius 84. The roller base body 82 preferably forms the tool roller spacing 56 with the stop roller 54. The tool roller spacing 56 typically forms a nominal dimension for the total material thickness 62 of the closure tab band 32 assembled from the individual bands. In other words, the tool roller spacing 56 can be the sum of the hook band thickness 58, the carrier layer band thickness 60, and optionally a band thickness 86 of the additional carrier layer band 34.
[0105] The carrier layer tape thickness 60 of the carrier layer tape 20 is preferably constant. In other words, the material thickness 58 of the carrier layer tape 20 does not change. This allows a constant strength of the carrier layer tape 20 and thus of the closure flap tape 32 to be achieved. Furthermore, the manufacturing process 10 and the roller tools 50 can be kept simple, thereby minimizing costs. Preferably, the tape thickness 86 of the additional carrier layer tape 34 and / or the hook tape thickness 58 is also constant. This allows the aforementioned advantages to be enhanced.
[0106] In a special embodiment, the tool roller spacing 56 can be smaller than the total material thickness 62 of the closure tab strip 32. This can cause the strips to be pressed together in the joining unit 48, thereby increasing the adhesion of the strips to one another.
[0107] As shown, the tool roll 52 can have at least one, here several, punching webs 88. The punching webs 88 can be arranged or formed on the tool roll 52. Preferably, the punching webs 88 are arranged or formed uniformly distributed over the circumference of the tool roll 52. The punching webs 88 protrude in the radial direction of the tool roll 52 by a web height 90 above the roll base body 82 and are designed to separate the hook sections 28 from the hook band 18. Typically, the web height 90 is the size of the hook band thickness 58. This can prevent the carrier layer band 20 from being damaged when the hook sections 28 are separated.
[0108] In a particular embodiment, the web height 90 can be designed to be less than the hook band thickness 58 in order to accommodate compression of the hook band 18 when the bands are pressed together in the joining unit 48. The web height 90 preferably corresponds to the hook band thickness 58 in a compressed state of the hook band 18.
[0109] In a particularly preferred embodiment, the web height 90 can be less than the hook band thickness 58 in a compressed state of the hook band 18. As a result, the hook band 18 is not completely severed, whereby damage to the carrier layer band 20 can be prevented even more reliably. The unsevered part of the hook band 18 has lower holding forces with respect to the hook section 28 than the carrier layer band 20 has with respect to the hook section 28. When the hook band 18 is released from the carrier layer band 20, this can cause the hook section 28 to tear off from the hook band 18.
[0110] Preferably, the holding forces between the hook portion 28 and the carrier layer strip 20 are formed by introducing a binding agent (not shown) and / or by welding the hook portion 28 to the carrier layer strip 20 in the contact area 24. This makes the manufacturing behavior 10 more robust and less susceptible to defects.
[0111] The punching webs 88 are preferably designed as cutting edges. This allows the hook sections 28 to be separated with little force.
[0112] The punching webs 88 have a separating contour 92. The separating contour 92 is adapted to the hook section 28 to be separated. As shown, the separating contour 92 is rectangular. However, other separating contours 92 are also possible, for example, circular, elliptical, triangular, or polygonal separating contours 92. The separating contours 92 can also be square in shape, but with rounded corners.
[0113] Typically, the punching webs 88 of a tool roll 52 are of identical design, allowing the tool roll 52 to be manufactured particularly cost-effectively. However, to form differently shaped hook sections 28, the punching webs 88 can also have different separating contours 92. The different separating contours 92 can be arranged or formed in a predetermined order on the tool roll 52.
[0114] As shown, the tool roller 52 can have a support section 94 projecting radially beyond the roller base body 82. The support section 94 thus has a support radius 96 that is larger than the base body radius 84. Typically, the support section 94 projects beyond the punching webs 88 by the thickness of the carrier layer strip 60 in the non-compressed state of the carrier layer strip 20.
[0115] Typically, the support section 94 has a radial distance from the stop roller 54 which corresponds to the strip thickness 86 of the further carrier layer strip 34 or the sum of the strip thickness 86 and the carrier layer strip thickness 60 of the carrier layer strip 20.
[0116] The support section 94 can thus be used to guide the further carrier layer band 34 and / or the carrier layer band 20 if a band width 98 of the further carrier layer band 34 and / or a carrier layer band width 100 of the carrier layer band 20 exceeds a hook band width 102.
[0117] As shown, the support section 94 guides the further carrier layer band 34 in a section projecting by the projection 104 over the hook band 18 and the carrier layer band 20.
[0118] To form the closure tab band 32 (see Figs. 2, 3, 5), it can be provided that, before the carrier layer band 20 and the further carrier layer band 34 are placed together, a binding agent is introduced into the contact area 106 between the carrier layer band 20 and the further carrier layer band 34. This can achieve a particularly strong connection between the bands.
[0119] As shown, the resulting closure tab band 32 has a closure tab band width 76 which corresponds to the band width 98 of the further carrier layer band 34.
[0120] Fig. 5 shows a schematically illustrated section of an exemplary closure tab band 32.
[0121] The closure flap band 32 comprises the carrier layer band 20 and a plurality of hook sections 28. The hook sections 28 are of identical design and are arranged or attached to the carrier layer band 20 in a row along a main band extension 110. The hook sections 28 are equally spaced from one another or are at the same distance from the adjacent hook section 28. The main band extension 110 runs perpendicular to the closure band width 76.
[0122] As shown, the closure tab band 32, or the carrier layer band 20 and / or the further carrier layer band 34 (see Figs. 3, 4, 6) can have a pre-embossed band edge 112, which is serrated here.
[0123] The closure tab strip 32 is suitable for manufacturing closure tabs 12. For this purpose, the closure tab strip 32 can be divided along dividing lines 114, thereby forming the closure tab edges 38 (see Figs. 6-8). The dividing lines 114 can be straight and / or curved, as shown. Angular dividing lines 114 are also conceivable.
[0124] When cutting the closure tab band 32, a minimum distance 116 is preferably maintained from the dividing line 114 to the respective hook section(s) 28. In other words, the hook section 28 does not form part of the closure tab edge 38 of the closure tab 12 to be manufactured (see Figs. 6-8).
[0125] Fig. 6 shows an exemplary closure tab 12.
[0126] The closure tab 12 is made of a closure tab strip 32 (see Figs. 2-5) and has a textile or textile-like carrier layer 118, a textile or textile-like further carrier layer 120, and—here, several—hook sections 28. Preferably, the carrier layer 118 and / or the further carrier layer 120 are formed as a nonwoven.
[0127] The carrier layer 118 has a constant carrier layer thickness 60 (see Fig. 4). In other words, a cross-section of the carrier layer 118 is unweakened. This ensures a particularly uniform strength of the closure flap 12. As shown, several hook sections 28 are attached to the carrier layer 118.
[0128] The carrier layer 118 and the further carrier layer 120 extend between closure flap edges 38, which are formed at least partially by dividing the carrier layer 20 (see Figs. 2-5) and the further carrier layer 34 (see Figs. 3, 4) of a closure flap band 32 at - here straight - dividing lines 114 (see Fig. 5).
[0129] As shown, the carrier layer 118 and the further carrier layer 120 of the closure flap 12 together form a section 121 of two closure flap edges 38. The sections 121 have increased strength, thereby improving the handling of the closure flap 12.
[0130] The hook sections 28 are arranged or attached to the carrier layer 118 and have a circumferential minimum distance 116 from the closure flap edges 38. As a result, the hook sections 28 are recessed behind the closure edges 38, whereby the closure edges 38 can be formed softly and the wearing comfort of the diaper 14 is increased.
[0131] As shown, the hook portions 28 are elliptical and designed for releasably attaching the closure tab 12 to a diaper base body 122 (see Figs. 7, 8) of a diaper 14 (see Figs. 7, 8). Typically, the hook portions 28 form a hook-and-loop connection with the diaper base body 122.
[0132] As shown, the closure tab 12 has a fastening section 124 for fastening the closure tab 12 to the diaper base 122 and an actuating section 126 for actuating the closure tab 12. The fastening section 124 and the actuating section 126 are formed here by the further carrier layer 120. In other words, the further carrier layer 120 protrudes at least partially beyond the at least one carrier layer 118. The actuating section 126 is preferably formed on a side of the hook sections 28 opposite the fastening section 124. This makes actuating the actuating section 124 easier. When the closure tab 12 is fastened to the diaper base body 122, the actuating portion 124 is flexible, or not connected to the diaper base body 122, so that gripping of the actuating portion 126 is possible and release of the fastening by the hook portions 28 is simplified.
[0133] The fastening section 124 serves to fasten, in particular to glue, the closure flap 12 to the diaper base body 122. The extension of the fastening section 124 can be adapted to a type of diaper 14.
[0134] The fastening section 124 preferably has at least the hook band width 102 in a closure direction 128 (see Figs. 7, 8), particularly preferably twice the hook band width 102. This allows for a particularly secure fastening of the closure tab 12 to the diaper base body 122.
[0135] The actuating section 126 has at least one-third of the hook band width 102 in the closing direction 128, particularly preferably the hook band width 102. This ensures simple and quick actuation.
[0136] As shown, the closure tab 12 can have a closure tab length 130. The closure tab length 130 is preferably at least the closure tab band width 76, particularly preferably at least twice the closure tab band width 76.
[0137] Fig. 7 shows an exemplary type of diaper 14.
[0138] The diaper 14 comprises a diaper body 122 and two closure tabs 12 in an unattached state. In the unattached state, the closure tabs 12 are not attached to an adhesive portion 132 (so-called "target area") of the diaper body 122 by means of the hook portions 28—here two each—which facilitates the application of the diaper 14 to a human wearer (not shown).
[0139] When the diaper 14 is applied to the wearer, the closure tabs 12 can be applied to the respective adhesive section 132 of the diaper base 122, thereby creating a hook-and-loop connection between the hook sections 28 and the respective adhesive section 132. This enables the diaper to be held securely in place when applied. The application of the closure tab 12 is illustrated by the closure direction 128 (dashed arrow). The hook section 28 extends in the closure direction 128 as shown, thereby increasing the holding force of the hook section 28 on the adhesive section 132.
[0140] To remove the diaper 14, the hook and loop connection formed by the hook portion 28 and the adhesive portion 132 can be released by pulling the hook portion 28 off the adhesive portion 132.
[0141] The hook sections 28 are preferably set back behind the respective closure edge 38 by the minimum distance 116 (see Figs. 5, 6). This eliminates the hard and / or sharp-edged closure edge 38 caused by the hook section 28, thereby increasing the wearing comfort of the diaper 14 and reducing the risk of injury when putting it on and taking it off.
[0142] The closure tabs 12 are arranged or fastened, in particular glued, to the diaper base body 122 by means of the respective fastening section 124.
[0143] The illustrated type of diaper 14 is designed to be closed in the pelvic region of a wearer. This allows the diaper 14 to be easily applied from a frontal direction by a person entrusted with applying the diaper 14. Fig. 8 shows another exemplary type of diaper 14.
[0144] The diaper 14 has a diaper body 122 and two closure tabs 12, whereby only one of the closure tabs 12 is visible due to the illustration. Each closure tab 12 has three hook sections 28, as shown.
[0145] Typically, the illustrated type of diaper 14 is put on in a closed, pants-like state by inserting the wearer's legs (not shown). This allows for particularly simple and quick application of the diaper 14, especially while the wearer is standing. Furthermore, the wearer can pull the diaper 14 down and up again, especially while "getting potty trained."
[0146] To remove the diaper 14, the closure tabs 12 can be released by detaching the hook portions 28 from the respective adhesive portion 132, and the diaper body 122 can be opened. This allows for hygienic removal of the diaper 14 without extending the legs through the used diaper 14.
[0147] As shown, the closure tabs 12, when the diaper 14 is applied to the wearer, are designed to hook and loop the hook portions 28 (here three) of each closure tab 12 to the respective adhesive portion 132 directly on a hip (not shown) of the wearer. This enables the particularly hygienic opening of the diaper 14.
[0148] The hook sections 28 of the closure tabs 12 extend transversely to the closure direction 128 of the diaper 14. This enables a wide closure and thus a secure application and a secure hold of the diaper 14 on the hip of the wearer.
[0149] The hook sections 28 set back behind the closure edges 38 enable the diaper 14 to be highly comfortable to wear and reduce the risk of injury to the wearer when putting the diaper 14 on and taking it off. Taking all of the figures of the drawing together, the invention relates to a manufacturing method 10 for producing a closure tab tape 32 for producing closure tabs 12 for a diaper 14. The manufacturing method 10 provides for the flat placement of two or more tapes, with at least one of the tapes being designed as a hook tape 18. During the placement process, hook sections 48 are preferably punched out of the hook tape 18 and attached to a carrier layer tape 20. The produced closure tab tape 32 can then be fed to further process steps for forming the closure tab 12.The invention also relates to a manufacturing device 40 that enables the closure flap 32 to be manufactured according to the invention. The invention further relates to a diaper 14 that can be manufactured particularly inexpensively and, moreover, ensures high wearing comfort with a low risk of injury.
