Description

[0001] The invention relates to a diaper fastening tape and a semi-finished tape material for producing a diaper fastening tape, a method for producing a diaper fastening tape or a semi-finished tape material and a method for closing a diaper.

[0002] Such diaper fastening tapes are known, for example, from EP 1 725 201 B1, EP 1 139 955 A1, DE 10 2010 026 719 A1, EP 0 755 665 A1, or EP 0 321 232 A1. These have a permanent region for permanently connecting the diaper fastening tape to a diaper and a user region for detachably connecting it to a diaper, in particular to a landing zone of the diaper.

[0003] WO 98 / 027922 A1 and WO 99 / 001100 A1 also disclose such diaper fastening tapes, the latter two documents disclosing arrangements in which a mechanical component of a two-component mechanical fastening system and an adhesive component of an adhesive fastening system are arranged one inside the other or at the same height in a longitudinal direction of the respective diaper fastening tapes.

[0004] EP 0 321 232 A1, DE 10 2010 026 719 A1 and EP 0 755 665 A1, on the other hand, disclose arrangements in which the mechanical component and the adhesive component are arranged one behind the other in the longitudinal direction of the diaper fastening tape, wherein the adhesive layer also extends in these arrangements up to the level of the mechanical component below the mechanical component in order to fix it to a carrier tape, whereby, however, these regions of the adhesive layer cannot serve as the adhesive component of an adhesive fastening system since they are permanently covered by the mechanical component.EP 1 725 201 B1 shows, on the one hand, arrangements in which the mechanical component and the adhesive component are arranged strictly one behind the other in the longitudinal direction of the diaper fastening tape, and, on the other hand, arrangements in which the mechanical component and the adhesive component are arranged one inside the other or at the same height in the longitudinal direction of the respective diaper fastening tapes. In particular, DE 10 2010 026 719 A1 and EP 1 725 201 B1 disclose a Y-bond in the permanent region, the two legs of which are provided for permanently attaching the diaper fastening tape to a diaper on both sides of the diaper, wherein one of the legs is optionally designed as a release tape, so that in a delivery position, the adhesive component of the closure system, which is intended to enable a detachable connection, can releasably rest on the release tape.

[0005] EP 0 780 109 A2 also discloses, in some embodiments, the combination of a mechanical component of a two-component mechanical closure system and an adhesive component for a user area for releasable connection to a diaper, or the use of a Y-bond arrangement in the permanent area. This document also provides general information on the desirable adhesive forces between a diaper outer skin and an adhesive zone of diaper fastening tapes.

[0006] It is an object of the present invention to provide diaper fastening tapes, semi-finished tape material for producing a diaper fastening tape, methods for producing a diaper fastening tape or a semi-finished tape material and methods for closing a diaper, in which unwanted connections of the adhesive or mechanical components are avoided as far as possible until the diaper fastening tape is brought into its fastening position.

[0007] The object of the invention is achieved by diaper fastening tapes and semi-finished tape materials for producing a diaper fastening tape, methods for producing a diaper fastening tape or a semi-finished tape material, and methods for closing a diaper with the features of the independent claims. Further advantageous embodiments, possibly also independent of these, can be found in the subclaims and the following description.

[0008] Unintentional connections between the adhesive or mechanical components of the respective fastening systems can occur, for example, if these components become tangled or stuck to components, such as certain surface areas of the diaper, in the delivery position of the diaper fastening tape when it is attached to the diaper, making it impossible or difficult to move the diaper fastening tape into a secure position. There is also a risk that detaching such unintentional connections could cause damage to the diaper or contaminate the corresponding components.

[0009] Such unwanted connections can be avoided as far as possible by a diaper fastening tape with a permanent region for permanent connections of the diaper fastening tape to a diaper and with a user region for detachable connection to a diaper by means of a two-component mechanical fastening system and an adhesive fastening system, in which a mechanical component of the two-component mechanical fastening system and an adhesive component of the adhesive fastening system are arranged in the user region, if this is characterized in that a folding region is arranged between the mechanical component and the adhesive component.Such a design makes it possible to fold the mechanical components onto the adhesive component - and vice versa - so that they can cover and protect each other at certain times, and therefore in particular as long as they are in a delivery position.

[0010] Various measures are conceivable for designing the folding area. For example, it can be represented by one or more grooves, for example in a carrier tape. Other material weakenings that facilitate folding in the folding area or improve its precision can also be provided in the folding area. In particular, the folding area can be designed without adhesive or without an adhesive coating, so that, in particular, blocking of the adhesive component or another adhesive, which can be used, for example, to attach the mechanical component or other assemblies, with each other or with itself can be reliably prevented.

[0011] Unintentional connections of the adhesive or mechanical components to other assemblies or objects can also be avoided as far as possible by a diaper fastening tape with a permanent region for permanently connecting the diaper fastening tape to a diaper and a user region for detachable connection to a diaper by means of a two-component mechanical fastening system and an adhesive fastening system, in which a mechanical component of the two-component mechanical fastening system and an adhesive component of the adhesive fastening system are arranged in the user region, if the diaper fastening tape is characterized in that the mechanical component and the adhesive component cover one another in a delivery position of the diaper fastening tape and the mechanical component and the adhesive component are released in a fastening position of the diaper fastening tape.As already indicated above, covering in the delivery position means that the two components protect each other and in this way unwanted connections between these components and any other surfaces can be minimized.

[0012] Preferably, the covering is carried out in such a way that the adhesive component and the mechanical component face each other with regard to their surface side intended for a detachable connection to the diaper during covering, which has the result that the surface sides are then better protected against contact with other assemblies or other objects in order to avoid unwanted connections with such assemblies or objects.

[0013] It goes without saying that the covering does not necessarily have to be complete, as even partial covering is sufficient to reduce the risk of such unwanted connections. If necessary, additional components of the diaper fastening tape can be used for additional covering. Furthermore, the increased material thickness resulting from such covering can, if necessary, lead to a desired reduction in the risk of unwanted connections between the adhesive or mechanical components.

[0014] Such a cover can be realized in particular by folding, wherein such folding can be made more precise or easier, in particular by a folding area. On the other hand, a special design of a folding area, for example by creasing, can also be dispensed with if the adhesive and mechanical components can be folded onto one another in an operationally reliable manner in this way. In particular, it is conceivable that a natural thickness of the mechanical component can enable the mechanical and adhesive components to be folded onto or over one another in a sufficiently operationally reliable manner, since the mechanical component can, on the one hand, have an edge to make the fold more precise and, on the other hand, can sufficiently prevent the adhesive or the adhesive component from clogging itself or with one another, for example by forcing a sufficiently large folding radius.

[0015] In particular, in contrast to the diaper fastening tapes as disclosed in WO 98 / 027922 A1 or WO 99 / 001100 A1, but also in certain arrangements of EP 1 725 201 B1, in which the mechanical components and the adhesive components are each designed to merge into one another and in which corresponding areas with adhesive components and with mechanical components are located at the same height in the longitudinal direction, the folding area provided between the mechanical component and the adhesive component enables the adhesive component and the mechanical component to cover one another in certain operating positions, in particular therefore in a delivery position, in order to be released in the fastening position by releasing this cover.Given the close spatial arrangement of the adhesive and mechanical components in the arrangements according to the aforementioned prior art, it is mechanically impossible for the mechanical component and the adhesive component to cover each other in a delivery position in order to be released accordingly in a fastening position. The same ultimately applies to the arrangements shown in EP 0 321 232 A1, DE 10 2010 026 719 A1, and EP 0 755 665 A1, but also in some embodiments of EP 1 725 201 B1, since a folding region between the mechanical component and the adhesive component is not provided there, and due to the spatial proximity, covering or reliably folding the adhesive component onto the mechanical component, or vice versa, is not possible.

[0016] In order to reliably prevent unwanted connections of the adhesive or mechanical components in the state of the art, separate release tapes or additional covers are necessary, which accordingly increases the costs for such diaper fastening tapes.

[0017] Preferably, the detachable connection is made with or at a defined landing zone on a diaper, which is well known in the art. This landing zone can, for example, be a frontal tape provided with the second component of the mechanical fastening system, for example, with the loops of a hook-and-loop fastening system, if the mechanical component on the diaper fastening tape is provided by hooks. On the other hand, it is also conceivable for the backsheet of the diaper as such or as a whole to be provided with the second component of the mechanical fastening system.

[0018] Two-component mechanical fastening systems, particularly the hook-and-loop fastening systems mentioned above, as well as hook-and-loop fasteners, hook-and-eye fasteners, button-type fasteners, or detachable snap fasteners, and the like, are suitable. Mechanical fastening systems optimized for the application of shear forces, such as pincushion-like arrangements, can also be used. Their needle-like projections do not snag in corresponding components but merely prevent slipping parallel to the surface, especially if the adhesive component can additionally counteract peel forces, for example.

[0019] Unintentional connections of the adhesive or mechanical components can also be avoided as far as possible until the diaper fastening tape is brought into its fastening position if a semi-finished tape material for producing a diaper fastening tape extending longitudinally along a longitudinal direction oriented perpendicular to a tape extension direction of the semi-finished tape material, in which a mechanical component of the two-component mechanical fastening system extending in the tape extension direction and an adhesive component of the adhesive fastening system extending in the tape extension direction are arranged on a carrier tape extending in the tape extension direction, is characterized in that a folding region extending in the tape extension direction is arranged between the mechanical component and the adhesive component.

[0020] The semi-finished strip material can then be wound into a roll or spool or laid in loops or bows so that it can be transported in relatively large quantities and, for example, fed to a diaper machine.

[0021] During the production of the diaper fastening tape, the mechanical component and the adhesive component can then be folded onto each other so that they cover each other. This can be done, for example, at the diaper machine, especially if the diaper fastening tape has already been separated from the semi-finished tape material, i.e., immediately when the diaper is manufactured and moved into a delivery position and packaged for shipment.

[0022] On the other hand, it is also conceivable that the semi-finished strip material is already provided in such a way that the mechanical component and the adhesive component cover each other, so that even with this semi-finished strip material the risk of unwanted connections that the adhesive or mechanical components could form can be minimized as much as possible.

[0023] Accordingly, the risk of such unwanted connections can be avoided as far as possible if a semi-finished tape material for producing a diaper fastening tape extending longitudinally along a longitudinal direction oriented perpendicular to a tape extension direction of the semi-finished tape material, in which a mechanical component of the two-component mechanical fastening system extending in the tape extension direction and an adhesive component of the adhesive fastening system extending in the tape extension direction are arranged on a carrier tape extending in the tape extension direction, is characterized in that the mechanical component and the adhesive component cover one another.

[0024] The latter advantage is particularly true when the diaper fastener tape with its permanent area is permanently attached to the diaper, which usually only happens on the diaper machine.

[0025] Preferably, the mechanical component and the adhesive component are folded onto each other before the diaper fastening tape is permanently applied to the diaper, since the risk of unwanted connections occurring is relatively high during application, which is usually carried out at very high speeds and with relatively high forces.

[0026] Accordingly, it is also advantageous if the mechanical component and the adhesive component are folded onto one another before the tape material is wound up, since within a spool the different layers of the spool are pressed relatively strongly onto one another in order to ensure that the spool has sufficient stability, so that there is also a relatively high risk that the adhesive or mechanical components will form unwanted connections, which can be counteracted by folding them onto one another.

[0027] Preferably, the semi-finished strip material is wound onto a cross-wound spool, as such a cross-wound spool can be wound relatively stably even with relatively large thickness differences in the semi-finished strip material perpendicular to the strip extension direction. Such large thickness differences are to be expected particularly in the folded areas, as the strip material will naturally be thicker there due to the folding. It should also be considered that the mechanical component is usually relatively thick anyway, which further exacerbates the aforementioned adverse effect.

[0028] If the diaper is then applied to a body as intended after being removed from its outer packaging, the mechanical component and the adhesive component can be released, or the fold area can be stretched. This allows the diaper fastener tape to be moved into its fastening position, in which the mechanical component and the adhesive component are released and can be brought into contact with the landing zone of the diaper or elsewhere on the diaper. This allows the diaper fastener tape to be permanently connected to the diaper with its permanent area and releasably connected to the diaper with its usage area, thus closing the diaper. By opening the releasable connection, the diaper can still be easily opened.

[0029] Preferably, the mechanical component adheres to the adhesive component in the delivery position of the diaper fastening tape or semi-finished tape material. This allows the covering of the two components to be relatively stable, thus minimizing the risk of the two components accidentally separating from each other and thus the risk of these components becoming accidentally connected to any other assemblies or objects.

[0030] Depending on the specific implementation of the present invention, the adhesion can be configured such that the adhesive layer providing the adhesive component remains partially or completely attached to the mechanical component when the diaper fastening tape is moved into its fastening position. This can then lead to diaper fastening tapes that, in the fastening position, correspond to the arrangements described in WO 98 / 027922 A1 or WO 99 / 001100 A1, although these documents do not contain any indications that the mechanical component and the adhesive component protectively cover each other in the delivery position.

[0031] Preferably, the mechanical component and the adhesive component adhere to each other with an opening force between 2 N and 8 N per 25 mm. This opening force ensures, on the one hand, a sufficiently reliable cover in the delivery position, while, on the other hand, the cover can still be manually removed easily, or the diaper fastening tape can be manually moved into its operating position with sufficient ease.

[0032] The opening force is preferably determined using a tensile testing device. The tensile testing device has a steel plate to which the 25 mm wide diaper fastening tape to be tested is adhered in such a way that the adhesive component is on the steel plate side and the mechanical component is on the side facing away from the steel plate. Immediately after adhesion, the test specimen is rolled back and forth once, preferably immediately, with a contact force of 2000 g and a speed of 300 mm / min in order to obtain a defined contact force. If necessary, the test specimen can then be heated at 70°C for between two hours and three weeks and then allowed to acclimate to room temperature for two hours to enable testing under extreme environmental conditions.

[0033] To determine the opening force, the mechanical component is then peeled off using the tensile testing device at a peel speed of 200 mm / min with a peel angle of 180° until the mechanical component is separated from the adhesive component.

[0034] Due to the mechanical components, force peaks will usually have to be measured, with the force being evaluated from the first clearly definable force peak onwards.

[0035] The above-mentioned determination of the opening force at between 2 N and 8 N per 25 mm is due to the fact that existing diaper fastening tapes are frequently found on the market in this or a similar width, so that measurements of diaper fastening tapes with this width lead to relatively representative results. It goes without saying that, by appropriate conversion, corresponding values ​​in N / mm can also be obtained directly, which then leads to a corresponding interval between 0.5 N / mm and 2 N / mm. Measurements can also be taken for other tape widths, which can then be converted accordingly.

[0036] Notwithstanding the fact that the aforementioned interval between 2 N and 8 N per 25 mm has proven to be very advantageous, it is advantageous if the opening force with which the mechanical component and the adhesive component adhere to one another exceeds 2 N, in particular 2.1 N or 2.2 N, per 25 mm. This can ensure that an unintentional separation of the adhesive and mechanical components from one another until the diaper fastening tape is intentionally moved into its fastening position does not occur, with relative operational reliability.

[0037] If the opening force does not exceed 8 N, in particular 7.8 N or 7.6 N, per 25 mm, it can be ensured that the mechanical component and the adhesive component can be separated manually with sufficient ease to move the diaper fastening tape into its fastening position.

[0038] Preferably, the diaper fastening tape has a longitudinal extension direction that can be defined from the permanent area to the user area. If necessary, such a longitudinal extension direction can also be defined in conjunction with other geometric features of the diaper fastening tape, for example, in conjunction with the arrangement of the individual components or taking into account a tape extension direction for a semi-finished tape material, as already explained above.

[0039] Preferably, the mechanical components and the adhesive components are arranged one behind the other in the longitudinal direction. This allows the two components to be clearly separated from each other, and any folding area between them can be provided in a structurally simple manner. It is then also relatively straightforward to arrange the mechanical components and the adhesive components so that they overlap each other in the delivery position.

[0040] In particular, it is advantageous if the mechanical component and the adhesive component do not overlap perpendicular to the longitudinal direction and parallel to the plane of extension of the diaper fastening tape in the fastening position of the diaper fastening tape, i.e., in the position in which it is intended to enable closure of the diaper. This means that covering by a fold or a folding area can then be provided in a structurally simple manner perpendicular to the longitudinal direction of the diaper fastening tape.

[0041] In the longitudinal direction, the order of the mechanical component and the adhesive component is initially irrelevant with regard to the basic idea of ​​the present invention, with the mechanical component preferably being provided on the side of a finger lift or on a side of the adhesive component facing away from the permanent area. As long as mutual masking is possible, one of the components can also be arranged on either side of the other component.

[0042] The diaper fastening tape preferably has four edges, two of which are preferably aligned parallel to its longitudinal direction and two perpendicular thereto.

[0043] If necessary, the permanent area and the user area can also overlap with respect to the longitudinal direction, in particular after a permanent attachment to a diaper, if, for example, the attachment in the permanent area can be realized via measures provided on a backside of a carrier tape, such as adhesive or welds or the like, while the measures provided for the releasable attachment in the user area, such as the mechanical component and / or the adhesive component, can be arranged on the front side of the carrier tape.

[0044] Preferably, the diaper fastening tape has a finger lift on an edge of the diaper fastening tape facing away from the permanent area. This can facilitate moving the diaper fastening tape into the fastening position, as a user can then relatively easily grasp this edge via the finger lift and release the cover of the mechanical component and the adhesive component.

[0045] An intermediate region, which may be elastic, for example, may be arranged between the permanent region and the user region. The intermediate region may also simply serve to ensure that the user region is appropriately spaced from the permanent region and the diaper ear located there after the diaper fastener tape has been permanently attached to a diaper, so that it can be easily positioned in a desired landing zone.

[0046] As already indicated above, the mechanical component and the adhesive component can be arranged on a carrier tape, which represents the basic structure of the diaper fastening tape and extends to the permanent area. Depending on the specific implementation of the diaper fastening tape, this carrier tape can also be composed of several components, for example, to impart a certain degree of elasticity or a desired feel. In this case, the carrier tape can be laminated from several layers or composed of several components along its length. The carrier tape is preferably made of textile, as this ensures a pleasant feel. A nonwoven is particularly suitable for a textile carrier tape.

[0047] Preferably, the mechanical component and the adhesive component are each arranged on the same side of the carrier tape, which makes folding very easy. This also ensures that the adhesive area and the mechanical area structurally overlap each other and form as few unwanted connections as possible, since the carrier tape is always located on the outside when it is folded around the mechanical component and the adhesive component.

[0048] The folding area is therefore particularly preferably located in the carrier tape.

[0049] It is understood that the features of the solutions described above or in the claims may also be combined if necessary in order to be able to implement the advantages cumulatively.

[0050] Further advantages, objects, and features of the present invention will become apparent from the following description of exemplary embodiments, which are particularly illustrated in the accompanying drawings. In the drawings: Fig. 1 a diaper fastening tape in a delivery position or a semi-finished tape material in a schematic view of an edge 47 of the diaper fastening tape or the semi-finished tape material; Fig. 2 the diaper fastening tape Fig. 2 in a fastening position; Fig. 3 a first winding of the semi-finished strip material according to Fig. 1; Fig. 4 a second winding of the semi-finished strip material according to Fig. 1 as cross-wound bobbin; Fig. 5 a representation of an exemplary test procedure; and Fig. 6 shows a representation of another exemplary test procedure.

[0051] The Fig. 1 and Fig. The diaper fastening tape 10 shown as an example in Figure 2 has a permanent region 11 and a user region 12, wherein the permanent region 11 serves to permanently fasten the diaper fastening tape to a diaper, while the user region 12 serves to releasably fasten the diaper fastening tape 10 to a diaper, whereby the diaper can be closed or opened as required.

[0052] In this exemplary embodiment, an intermediate region 13 is provided between the permanent region 11 and the user region 12. This intermediate region serves to provide a defined distance between the user region 12 and the permanent region 11, so that the user region 12 can be attached to the diaper in the desired manner and at a desired distance from the permanent region 11 or from the area of ​​the diaper to or in which the permanent region 11 is attached. Depending on the specific implementation, the intermediate region 13 may also be omitted. It is also conceivable to design the intermediate region 13, for example, to be elastic.

[0053] The diaper fastening tape has two edges 47 (only in Fig. 3, since in the sectional view of the Fig. 1 and Fig. 2 not visible) and two edges 48, 49 perpendicular to the edge 47, wherein the edge 48 lies in the permanent area 11 and the edge 49 lies in the user area 12. At the edge 49, in the user area 12, a finger lift 14 is provided, which is intended to facilitate gripping the user area 12.

[0054] The diaper fastening tape 10 can be assigned a longitudinal extension direction 62.

[0055] If the diaper fastening tape 10 is made of a semi-finished tape material 60, as shown for example in Fig. 3 and Fig. 4, the latter only needs to be separated perpendicular to its tape extension direction 61 along the longitudinal extension 62 in order to be able to provide diaper fastening tapes 10 in each case.

[0056] Accordingly, the Fig. 1 and Fig. 2 also apply to the semi-finished strip materials 60 of the Fig. 3 and Fig. 4, whereby it depends on the form in which the semi-finished strip material 60 is wound, whether the cross section of the Fig. 1 or the cross section of the Fig. 2 is present.

[0057] While the Fig. 3 is provided in the form of a roll, the semi-finished strip material 60 shown in Fig. 4, the semi-finished strip material 60 is provided in the form of a cross-wound coil 69.

[0058] The diaper fastening tape 10 and thus also the semi-finished tape material 60 each have a textile carrier tape 15, which ultimately forms the structural integrity of the diaper fastening tape 10 or the semi-finished tape material 60. In the present exemplary embodiment, the textile carrier tape 15 is constructed in only one piece. It is understood that it can also comprise a laminate made up of several layers if necessary. It is also conceivable for the textile carrier tape 15 to be composed of several individual strips, as are sufficiently known from the prior art. It is also understood that, instead of the textile carrier tape 15, other carrier tapes 15 can also be used accordingly.

[0059] On the one hand, the textile carrier tape 15 carries a permanent adhesive 39 in the permanent area 11, which is selected such that it can be permanently bonded to a diaper.

[0060] In addition, the textile carrier tape 15 carries, on the one hand, an adhesive layer which forms an adhesive component 31 of an adhesive closure system, and adhesive 38, by means of which, on the one hand, a mechanical component 21 of a two-component mechanical closure system and, on the other hand, a layer forming the finger lift 14 are fastened to the carrier tape 15 or the diaper closure tape 10.

[0061] Between the mechanical component 21 or the adhesive 38 on the one hand and the adhesive component 31 on the other hand, a folding area 41 is provided, which allows the mechanical component 21 to be folded onto the adhesive component 31, as shown in Fig. 1 is shown.

[0062] In this way, a delivery position 51 can be provided in which the mechanical component 21 and the adhesive component 31 are prevented from forming unwanted connections with other assemblies or objects in a relatively cost-effective and effective manner.

[0063] If the folding is released or the mechanical component 21 and the adhesive component 31 are released, as shown in Fig. 2, the components 21, 31 can interact with corresponding assemblies of a diaper and together enable the user area 12 to be attached to a diaper.

[0064] Especially in the Fig. 3 and Fig. The arrangements shown in Figure 4 can then effectively prevent the adhesive component 31 or the mechanical component 21 from forming an unwanted connection with the carrier tape 15 of an inner layer of the semi-finished tape material 60, which could otherwise lead to contamination of the adhesive component 31 or to mechanical damage to the textile carrier tape 15.

[0065] Through the folding, as in Fig. 1, with a suitable design, a layer print, as in the case of the Fig. 3 and Fig. 4 can also act on the permanent adhesive 39, so that here too the risk of unwanted blocking of the permanent adhesive 39 with an inner or lower layer in the rolls can be minimized.

[0066] As immediately in Fig. 2, both the mechanical component 21 and the adhesive component 31 are arranged on a front side 58 of the carrier tape 15. They are therefore located on the same side of the carrier tape 15. A rear side 59 can also be assigned to the carrier tape 15, facing away from the front side 58.

[0067] It is understood that in alternative embodiments, the adhesive component 31 does not necessarily have to be arranged on the permanent area side of the mechanical component 21. Rather, it is also conceivable that the adhesive component 31 can be provided on both sides or on the side of the mechanical component 21 facing away from the permanent area 11.

[0068] It is understood that the adhesive component 31, with regard to its adhesive properties, is preferably selected such that it can exert its adhesive effect on a diaper or in one of its landing zones as intended. The mechanical component 21 is also selected accordingly and, in the present exemplary embodiment, has hooks or protruding tips, as indicated by the triangular shape, so that the second component of the two-component closure system is preferably formed by loops or textile material into which the hooks or tips can be inserted. It is understood that in deviating embodiments, the relationships in this regard can also be selected the other way around, so that corresponding hooks or tips could be provided, for example, in a landing zone on the diaper itself.

[0069] To ensure that the opening force between the mechanical component 21 and the adhesive component 31 is not too large or too small, so that, on the one hand, a reliable cover in the delivery position 51 and, on the other hand, manual transfer to the fastening position 52 is sufficiently easy, the mechanical component 21 and the adhesive component 31 are further coordinated with one another in such a way that, when applied to a steel plate with a test specimen width of 25 mm, they are pressed back and forth once using a rolling device at a contact pressure of 2000 g and a rolling speed of 300 mm / min and then separated from one another using a tensile testing device. Preferably, the carrier tape 15 is glued to the steel plate with its back side 59 in such a way that, in the folded state, the adhesive component 31 is located on the side of the steel plate.The aforementioned rolling over then takes place using a rolling device.

[0070] Depending on the specific test requirements, the test specimen prepared in this way can be stored at 70°C for two hours to three weeks, followed by two hours of conditioning at room temperature before the carrier tape 15 is clamped into a tensile testing device at the finger lift 14 and pulled off at an angle of 180°, so that the folding area 41 opens and the mechanical component 21 and the adhesive component 31 are released. The result of the force that must be applied by the tensile testing device can be found, for example, in Fig. 5 and Fig. 6, whereby a substantive evaluation of the measurement result only takes place from the first clearly developed force peak.

[0071] In Fig. 5 and Fig.6 shows clear force peaks caused by the individual rows of hooks of the mechanical component 21. It can be seen that the opening force is above 2.2 N and below 7.8 N per 25 mm.

[0072] Those skilled in the art are well aware of sufficient measures to specifically influence this opening force, which can be achieved, for example, by selecting and matching suitable adhesives or by the density of the hooks and their precise shape.

[0073] Compared to the adhesive of the adhesive component 31, the adhesive 38 for the finger lift 14 and the mechanical component 21 is selected such that the mechanical component 21 remains on the carrier tape 15 when the adhesive component 31 and the mechanical component 21 are to be separated from one another. If necessary, a larger area over which the mechanical component 21 interacts with the adhesive 38 compared to the point-like contacts with the adhesive component 31 may be sufficient to ensure that the mechanical component 21 remains on the carrier tape 15 when the adhesive component 31 and the mechanical component 21 are to be separated from one another. In particular, the adhesive 38 can also be designed as a permanent adhesive if necessary.

[0074] If necessary, the adhesive of the adhesive component 31 can also be selected such that it breaks during the transition to the fastening position 52 and partially remains on the mechanical component 21.

[0075] In the present embodiment, the folding region 41 is designed without an adhesive coating, so that in particular blocking of the adhesive component 31 or the adhesive 38 with each other or with themselves can be reliably avoided.
