Description

The invention relates to a connecting element for end regions to be joined together of carrier tapes of corsetry, in particular lingerie, which has a plurality of substantially superposed textile layers, of which at least one band layer carries a connecting part, such as at least one hook, an eyelet or the like, and between two in particular outer band layers is provided an insert for increasing the wearing comfort, which is fastened by means of a connection in the region of side edges of the connecting element to at least one of the band layers.

Such a connecting element goes from that already published in 1958 US 2,861,276 in which an insert is to be present between a rear layer in contact with the skin and another layer which carries the eyelets. The layer is intended to improve the wearing comfort of the connecting part. To produce such a connecting part, all the layers are placed one on top of the other, separated and then edged with three sides by means of an elastic plastic band. To produce a solid connection, the plastic strip is to be vulcanized and pressed under pressure onto the closure part. The insert is attached only by the elastic elastic band located outside. It is feared that the paragraph between the plastic tape and the outer layer rests on the skin of the user and unpleasant presses and rubs.

In the GB 876,973 shown an eyelet tape having multiple tape layers, which are referred to there as a "strip" and a "cover strip". The lower strip should in this case be folded in itself, so that two superimposed layers arise, wherein one edge of the lower of the two layers is folded inwards. The cover strip lying above the strip is likewise folded inwards in the region of its two side edges, so that its two side edge areas are respectively facing the center of the cover strip. The eyelets to be fastened to the band rest on the upper layer of the strip and are partially pushed under the cover strip. To attach the eyelets, the lower layer of the strip is folded away and the eyelets are then sewn by means of seams to the cover strip and to the upper layer of the strip. In addition, another seam penetrates both the two layers of the cover strip and one of the layers of the strip. The further seam runs approximately centrally to the connecting element and thus at a considerable distance from side edges of the connecting element. During the production of the connecting element, the lower layer of the strip is then to be folded under the layer of the strip, so that the further seam is covered on the underside of the connecting element. It is to be feared that the eyelets will be noticeable as an uncomfortable feeling of pressure even in the case of this connecting element, which is comparatively complicated to manufacture. In addition, the layers of the connecting element are only partially fixed to each other.

Fasteners are often sewn to the ends of the carrier tapes and are generally formed as either an eyelet or eye strap or a hook tape. Such eyelet and hook tapes can be connected together and then together each form a closure for a garment.

In the production of Ösenbänder often the eyelets are first attached in a known arrangement to an endless base tape by sewing. For this purpose, a plurality of so-called folding tapes are sewn in partially overlapping arrangement on the baseband folded on its two longitudinal sides, wherein the eyelets during sewing of the folding tapes together with these running through substantially parallel to the longitudinal sides of the base tape seams on the base tape or the folding bands be attached. Subsequently, the base tape is divided together with the attached fold bands by transverse to its longitudinal direction cuts into individual, the Ösenbänder forming sections.

In known manufacturing processes, the separation of the individual eyelet bands from the endless base tape takes place in the heat-welding process, for example in the ultrasonic white process, so that the cut edges of the base tape and the folding tapes are connected to one another at the same time. Although this type of separation from the eyelet bands from the endless base tape or the likewise endless folding tapes is indeed simple in terms of manufacturing technology and accordingly inexpensive. However, this creates a solid and very sharp connection edge. Since the baseband and the folding tapes are separated by the cuts directed transversely to their longitudinal sides, these connecting edges form the longitudinal edges of the eyelet tapes.

In the case of underwear to be worn directly on the skin, for example bra, whose straps rest with a certain force on the skin, there is therefore a risk that the connecting edges, which also rest on the skin, cut the eyelet bands into the skin. This results in an unpleasant feeling, which can also lead to skin irritation.

The conditions are similar in the case of hook bands, for the production of which an endless base band is usually used. This is first formed by folding its two long sides into a kind of tube, with its folded areas overlap slightly and are substantially the same width. The hooks to be arranged in the overlap area are also provided by means of a hook fastened substantially parallel to the longitudinal sides of the base tape seam on the base tape, at the same time all superimposed layers of the base tape are joined together.

Again, the baseband with the attached hooks is divided by transverse to its longitudinal direction cuts into individual sections forming the hook bands. Before the separation of the individual hook tapes, the base tape is folded substantially centrally around a folding edge running parallel to its longitudinal direction, its region carrying the hook resting on the hook-free region.

If the separation of the individual hook tapes from the endless base tape also takes place in the heat-welding process, the cut edges of the superimposed areas of the base tape are connected to one another by the separating operation. Since here too the cut edge run transversely to the longitudinal sides of the base tape, these connecting edges also form the front edges of the hook tapes produced in this way. This also solve the connection edges of the hook straps in directly on the skin to be worn underwear an uncomfortable feeling, which can lead to skin irritation.

In order to create a better comfort in connection with such fasteners, is in the EP 1 180 948 B1 already proposed to fold a plurality of closure parts, namely hooks, supporting base band parallel to the longitudinal course of the base band. As a result, the closure parts reach the inside of the folded base band. Subsequently, with transverse to the longitudinal course of the baseband separating weld seams closure elements are separated from the baseband. By destroying the closure elements produced in this way, on the one hand, the closure parts reach the outside and the sharp edges of the separating weld seams reach an inside of the closure elements. The sharp edges can therefore not rest on the skin and interfere there.

In an alternative embodiment of the EP 1 180 948 is placed on a loop-bearing side of the base tape a masking tape. Thereafter, connecting elements are cut out here with Trennschweissnähten and simultaneously connected the two layers of each connecting element at three longitudinal edges. Again, by splitting the sharp Trennschweissnähte be placed on an inner side of the connecting element, where they do not interfere. Despite the significantly increased wearing comfort, these fasteners can not be completely satisfied in terms of wearing comfort.

The invention is therefore an object of the invention to provide fasteners of the type mentioned, which have an improved wearing comfort despite a very inexpensive production.

This object is achieved in a connecting element according to claim 1, characterized in that the connection of band layers is at least partially between band layers of the connecting element in the use state of the connecting element. The object is also achieved by a method according to claim 10.

The invention thus provides to provide a connecting element with an insert, to attach the insert with a connection on the connecting element and to arrange the perceived as disturbing connection, such as a seam, between tape layers in the interior of the connecting element. In contrast to generic prior art fasteners according to the invention can be brought out of the skin contact area with the person using in spite of the deposit required for attachment of the insert on the connecting element. In the use state of the connecting element, the connection is preferably not accessible and are covered by tape layers.

In the context of the invention, the terms "tape ply" and "ply" are used both to refer to endless belts as commonly used in the manufacture of fasteners, as well as to portions of Endless belts, which are separated from the endless belts in the context of the manufacturing process of the connecting elements.

The insert is brought into a different position relative to the band layers by collapsing the at least two band layers, which may preferably be formed as textile layers. As a result, the insert (or a deposit belt) is initially placed on an outer side of the connecting element for its attachment to the connecting element, generates the connection and then brings the insert into a position between two band layers of the connecting element. In this position, the insert can perform particularly well their pressure-reducing function. By destroying the usually disturbing connection of the insert is also placed in the position between the tape layers at the same time.

In this position, no direct contact between the connection and the person using the laundry is possible.

Unlike for example in the case of US 2,861,276 the case is, it is also possible with the invention to produce a completely flat contact surface of the connecting element with the skin of the person using, whereby the contact surface of the Verbindungselemenets can rest over the entire surface of the skin without disturbing paragraphs.

In a preferred embodiment of the invention, in this case, the insert can be brought into a pocket, which results from two mutually connected band layers of the connecting element. Since it would be very difficult and time consuming due to entanglements of the textile layers with the insert to push the insert by hand into the bag, the turning / Versturzvorgang represents a fast, safe and still very easy way of placing the insert within the bag.

The insert may preferably comprise a compressible material, such as foam material, which determines the pressure sensation felt by the wearer / wearer in the area of the fasteners reduced. But it is in principle also usable as an insert any other material that contributes to an increase in wearing comfort, such as nonwoven material, nylon, velor, microfiber, silicone and more.

Since the two band or textile layers are preferably connected to one another by at least one connecting seam, the connecting seam produced before the turning / cambering process at least partially-preferably completely-arrives in the pocket. As a result, the usually sharp-edged connecting seam has no skin contact and therefore does not lead to a deterioration of the wearing comfort of the bodice. Since the invention preferably proceeds from fasteners and their manufacturing method, as shown in the EP 1 180 948 B1 are described, the disclosure of which is incorporated herein by reference.

In a preferred embodiment, the connecting seam of the tape layers is also used as a connection of the insert with the connecting element. By means of this fixation on the connecting element, as in other embodiments according to the invention, unintentional withdrawal or slippage of the insert from the connecting element or unintentional folding of the insert within the pocket can be reliably prevented on the one hand. On the other hand, it is not necessary for secure fixation of the insert to completely close the bag, for which an additional operation would be required. In addition, all band layers of the connecting element can be connected to each other in this way in only one step.

If, in the production of the connecting elements, the two band layers and an inlay strip are placed on top of each other and at the same time the respective sections for the respective connecting element separated from these bands, it is possible to make the shaping for all layers of the connecting element with only one step. By means of a Trennschweissvorgang can be made with the same one step in addition to and substantially simultaneously the connection of the individual layers together.

Further preferred embodiments of the invention will become apparent from the claims, the description and the drawings.

In Fig. 1 a base band 1 of Ösenbandes 2 is shown, which is provided at predetermined intervals with eyelets 3. How out Fig. 1 it can be seen, are on the base tape 1 more parallel to the longitudinal axis extending folding belts 4 sewn by means parallel to these extending fastening seams 5. The fastening seams 5 simultaneously serve for fastening the eyelets 3 on the base band 1, the longitudinal axis of which runs essentially transversely to the longitudinal axis of the base band 1.

The latter thus has on its one side a toe-bearing region 6 and on its other side an eyelet-free region 7.

The base tape 1 is preferably made of a soft material and may be formed by a flat band whose side areas not shown in the drawing are folded towards each other and overlap by a certain amount. The baseband 1 thus represents a tubular structure with overlapping bump edges. Within the baseband, a stabilizing band 8 may be provided. The stabilizing band 8 here has only the function to give the baseband a greater rigidity. It is preferably located completely within the base band 1 and is connected thereto due to the attachment seams of the connecting parts. Envelope edges 18, 19 of the base band represent - based on the position of use of the eyelet strip 2 when it is used in bras the two frontal boundaries of the eyelet strip 2.

How out Fig. 1 it can be seen, a preferably elastic cover strip 10 is placed on the eye-supporting portion 6 of the base band, which covers the eyelets 3. The cover strip 10 is in the case of the embodiment of Lycra (trademark of the company. DuPont) or a material with comparable properties. On the side of the loop-free area 7 an insert tape 20 is placed. In the exemplary embodiment, the insert belt 20 is made of foam. Preferably, as in the example shown, it may be a synthetic weldable foam. Such foams are offered, for example, by the company Recticel, Belgium. With respect to the base tape 1 with the sewn-on folding bands 4 is thus on one side of the cover tape 10 and on the other side of the insert tape 20th

In this layer of base tape 1, masking tape 10 and insert tape 20 successive sections of predetermined length from the base tape 1, masking tape 10 and insert tape 20 are separated by means of a thermal welding process, for example, an ultrasonic welding process. The length of this Sections determined - based on the position of use of the eyelet strip 2 to be produced, the height and width of the eyelet strip, for example, in a brassiere.

The used for use (not shown) Trennschweisswerkzeug can be designed so that it forms a separating weld seam 21 and 22 both during the separation process on both a first portion, as well as at this following second section. Optionally, a transverse weld seam can also be formed between the two separating welds 21, 22, whereby the severed portion can be at least substantially closed in the region of three of its side edges.

The resultant cut edges of the eyelet strip are welded to the cut edges 24 of the cover strip 10 and the cut edges 25a of the insert strip 20. These separating welds have u.a. the function of at least part of a connection between the insert and at least one of the band layers, by which the insert is fixed to the connecting element. This results in each case a solidified and very sharply pronounced connection edge 26 which is located on the respective outer side of the corresponding section. The eyelets 3 are still covered by the now welded cover strip 10.

As a result of a subsequent turning / Verstürzvorgang the section is turned / fallen in such a way that the cover strip 10 passes from the eyelet-bearing area 6 to the eyelet-free 7 area. The eyelets 3 are thereby exposed. At the same time reach the connection edges 26 (Trennschweissnähte) in the interior of the finished Ösenbandes, so that the two - in the position of use of Ösenbandes coming into contact with the skin - boundary edges 27, 28 of the eyelet strip 2 are formed substantially from the cover strip 10.

Also at the same time the separated portion of the insert belt 20 passes as an insert between the cover strip 10 and the base band 1. The insert is here fixed at three of four side edges over the connecting edge 26 on the connecting element thus produced. There is no insertion of the insert into the pocket formed by the separated sections of the cover strip 10 and the base tape 1 required 29, nor is there the danger that the insert is unintentionally removed from the bag.

The eyelet tape 2 thus produced can be sewn in a manner known per se to the carrier tape of a garment, for example to a carrier tape of a brassiere. In this case - based on the position of use of the brassiere - the two longer boundary edges the upper and lower portion of the sewn to the carrier tape Ösenbandes 2. Preferably due to increased compressibility of the inventive connecting element with respect to its thickness can be increased with the insert the comfort of the garment , The individual connecting parts and the connecting seam can be pressed even less on the skin in connection elements according to the invention and hardly be perceived as such by the wearer of the item of clothing.

In Fig. 4a For example, the various endless belt layers of one embodiment are shown for a hook tape 32 provided with hooks 33 at predetermined intervals. The latter are fastened to the base strip 31 by means of a fastening seam 34 running essentially parallel to the longitudinal axis of the base strip, the longitudinal axis (longitudinal extent) of which extends essentially transversely to the longitudinal axis of the base strip 31. The hooks 33 are sewn together with a folding tape 36 on the baseband. In the exemplary embodiment shown, the base band 31 completely wraps around a stabilizing band 39 once, with the two side regions of the base band 31 overlapping on the hook side of the base band and coming to rest on one another. The stabilizing band 39 is thus arranged completely within the base band 31. The upper side region of the base band 31 with the hooks 33 rests on the lower side region and could again be turned inwards to form a clean edge. The fastening seam 34 serves at the same time for fixing this Folds of the baseband 31, which thus represents a tubular structure with overlapping bump edges. The upper side region thus forms a hook-carrying region 37, while the lower side region forms a hook-free region 38. Basically, the areas 37 and 38 may be different or even the same size.

As shown on the right side of the illustration Fig. 4a is shown, parallel to the base tape 31 with hooks sewn on and the sewn-on folding tape 36, a cover strip 30, which may preferably comprise elastic material such as Lycra. The base band 31 and the hooks 33 are covered by the cover band 30 and therefore in this part of Fig. 4a represented by dashed lines.

On the other side (in the presentation of Fig. 4a the underside pointing to the drawing surface) of the base band is the in Fig. 4a left to be recognized insert tape 40 is arranged. The insert tape 40, for example made of elastically compressible foam, preferably has the same width as the base tape 31 in its folded state. From bottom to top is thus the insert belt 40 against the already 33 hook base band 31 and this base band 31 with the sewn-on folding tape against the cover strip 30 at.

In this position, the areas 37 and 38 and the insert belt 40 are separated by means of a thermal welding process, for example by means of ultrasound, successive sections of predetermined length of the base tape 31, insert tape 40 and masking tape 30 substantially simultaneously. Such a severed section is in Fig. 5 shown. The length of these sections determined - based on the position of use of the hook tape 32 to be produced, for example brassieres - the height or the width of the hook band 32nd

The purpose used for this purpose Trennschweißwerkzeug (not shown) may be formed so that it during the separation process both at a first portion and at this following second section each one Separating weld 41 forms. The resultant cut edges 42 of the base strip 31 are therefore welded to the cut edges 43 of the cover strip 30 and the insert strip 40, wherein in each case a solidified and very sharp connection edge 45 is formed, which is located on the respective outer side of the corresponding section. The hooks 33 are still covered by the cover strip 30, which is in Fig. 5 is indicated by dashed lines for the hook 33 and the folding edge of the folding belt 36.

Through an adjoining Verstürzvorgang the separated portion to the opening (side edge 49) of the pocket opposite part of the connecting edge 45 is turned / fallen so that on the one hand the hooks 33 are released from the cover 30 and on the other hand, the connection edges 45 (separating welds) in the Inside the finished hook tape 32 get ( Fig. 6 ). As a result, the two - in the position of use of the hook tape coming into contact with the skin - boundary edges 47, 48 of the hook tape formed by the material of the base tape 31. At the same time the severed and welded to the hook tape portions of the insert tape 40 passes between the base tape 31 and the cover 30. In this embodiment, the previously separated sections of the base tape 31 and the cover strip along the side edge 49 open pocket, in which the insert formed portion of the insert belt 40 is located.

The hook tape 32 produced in this way can be sewn in a manner known per se to the wearer's wear of a piece of clothing, for example to a support band of a brassiere. In this case - based on the position of use of the brassiere - the two boundary edges 47, 48, the upper and lower portions of the sewn to the carrier tape hook tape.

It was assumed above that, when separating the individual sections from both the hook band and the loop, a separating weld seam is formed on two sections each. This can be done with a relative simple cutting tool. In addition, any drop in baseband is avoided.

However, it is of course within the scope of the invention for separating the individual sections of the hook tape or the eyelet strip in each case to use a forming / separating welding tool. This makes it possible to form the respective two Trennschweissnähte at the same time at the same time.

The for the separation of the sections of the base band of the hook tape or loop tape used for use Form / Trennschweisswerkzeug is then provided only with two spaced apart the length of the individual sections to be arranged straight sonotrodes.

For the separation of the sections of the base band of the eyelet strip, it is possible to use an essentially U-shaped sonotrode or a U-shaped separating knife, which then produces the two longitudinal separating welds and at the same time a transverse separating weld seam extending therebetween can. The cross-cut seam may alternatively be a normal weld, i. not as a separating weld, be formed.

In another embodiment, it is also possible to separate one connecting element from the band layers with only one separating tool, which has only one sonotrode and one separating knife. In this case, one of its two longitudinal separating weld seams is produced in each case in the cutting area both in the respectively currently separated connecting element and in the next following connecting element. For example, by rotating the disconnected connecting element by 90 °, the transverse separating weld seam can subsequently be formed using the same or a second separating tool (sonotrode and separating knife). In order to obtain a uniform and as narrow as possible edge course can be separated at the transverse-separating weld material protruding material of the band layers. This makes it possible to avoid raising the cross-cut seam after the turning / Verstürzvorgang in the bag.

Although the described method produces a solidified connection edge in the region of the corresponding cover edge, this can initially be regarded as disadvantageous. Since, however, passes through the turning / Verstürzvorgang of Ösenbandes this connection edge between the eyelet-free area and the masking tape or the insert tape, the connecting edge has no negative impact on the comfort. At the same time even the advantage is achieved that the corresponding cover edge is solidified. <B> LIST OF REFERENCES </ b> 1 baseband 29 bag 2 Ösenband 30 masking tape 3 eyelets 31 baseband 4 pleat 32 hook tape 5 fastening seam 33 hook 6 bearer area 34 fastening seam 7 loop-free area 36 pleat 8th stabilization belt 37 hook-carrying area 10 masking tape 38 hook-free area 18 folding edge 39 stabilization belt 19 edge of the envelope 40 breaker strip 20 breaker strip 41 Separating weld 21 Separating weld 42 cutting edge 22 Separating weld 43 cutting edge 24 cutting edge 45 connecting edge 25 cutting edge 47 boundary edge 25a cutting edge 48 boundary edge 26 connecting edge 49 open side edge 27 boundary edge 28 boundary edge
