Method for attaching elastic bands or the like elastic parts on textile goods, as well as device for carrying out the method.

The invention relates to a method for attaching elastic bands or similar elastic parts to textile goods Made of natural or plastic, preferably on items of clothing and laundry, as well as a device for Implementation of this procedure.

Have elastic bands or similar resilient parts the purpose of pulling the piece of textile together, e.g. to put it on the body or a close-fitting finish on the waistband to achieve.

It is already known to equip the garments with hemstitching for fastening elastic bands through which the Elastic band is pulled through, the ends of which are connected to one another by sewing or welding. the For this purpose, elastic bands must first be inserted into the hemstitch. This represents its own and time consuming Work step that increases considerably with curved 'hollow seams. Furthermore, this means connecting the elastic cords always have an additional and separate work step. It is also known to sew an elastic band to the edge of an item of laundry. Because the elastic band with. the item of laundry must be connected, special precautions are to be taken for sewing *;.: -which, however, always the difficulty

remains, the elastic band on the intended seam line to be attached evenly with the required tension. ■ Particular difficulties arise when sewing the Elastics along a crooked line. Finally must Each elastic band is sewn on separately, with each sewing process requiring a certain amount of time. This The amount of work and time involved has a particularly unfavorable effect on clothing, especially underwear, that is after a one-off or thrown away with little use and must therefore be cheap.

The invention is therefore based on the task of attaching elastic bands to items of clothing, in particular items of laundry to simplify.

According to the invention, this object is achieved in that the elastic bands are in the tensioned state with the aid of a welding means are spot welded at least at their ends directly to the blank.

A particularly simple attachment of the elastic bands to aerr> Garment is obtained according to a further embodiment of the invention in that it is weldable with thermoplastics staggered, coated or twisted elastic bands are provided.

An embodiment of the subject matter of the invention is shown in the figures and is described in more detail below. Show it:

Pig. 1 ^ eigt a blank 1 of a piece of laundry made of cellulose or d _t -, l, _{shown for example as a baby 3 shose.} This blank 1 has extensions 1 * in the upper half compared to the lower half, which can be folded over around bending edges ^M a " The elastic bands 2 are preferably mixed with thermoplastics and are therefore weldable. The weldability can also be achieved in that the surface of the blank 1 in the area of the elastic bands is coated with thermoplastics or the elastic band 2 a welding agent in the form of a coating or a thread made of thermoplastics is added. The thread can simply be added to the elastic band 2 or twisted with it Cut 1 at 3 spot welded, depending on use For the purpose of the item of laundry, one or more point-like welded connections 5 'can be provided between the two visual welding points J at the ends.

The blank 1 rests on a bearing plate 4 which is equipped with the clamping devices. To elastic bands 2 too Attach it to the blank 1 along a curved line

To be able to, the bearing plate 4 has a number of needles or pins 5 which are arranged along the intended seam line. The needles or pins 5 can penetrate the blank 1 or rest on its edge. If the elastic band 2 is to be overlapped by parts of the blank 1, incisions or notches 6 are made from the outside in the inner apex of which a needle or a pin 5 is arranged (Fig. 3) Needles or pins 5 placed around and also attached to the bearing plate 4 under tension at its ends. It can be seen that an arbitrarily curved seam can be provided as a polygon by appropriate arrangement of the needles and pins 5 on the bearing plate 4. The elastic band 2 is expediently connected to the blank 1 at least at each incision 6 by a welding point 3 ^f , but preferably by two welding points J5 ' ^m * t located on both sides of the incision (FIG. 3).

The welding tool has a number of welding devices corresponding to the number and position of the intended welding points, so that all welding points 3 and 3 ¹ are produced in a single welding process.

After the welding process for fastening the elastic bands 2, a template J is placed in such a way that its side ^{edges come to lie along the bending edges "a w} and the lower edge along a further bending edge ⁿ b ⁿ . Then the extensions 1 * inwards and the lower part of the blank 1 folded up so that its outer areas come to rest on the extensions 1 '(Fig. 2)

In a further welding process, possibly with the addition of a welding agent, the parts lying on top of ^one another are connected to one another in the area of the extensions I 1. The ends of the elastic bands 2 can lie on top of one another or next to one another and be welded together. In this way, a sheared seam is created as a side seam, which can absorb great forces. Of course, each elastic band 2 must remain taut until the last welding process has been completed. After the welds have cooled down, the pre-tensioning can be released and the protruding rubber cord ends can be cut off. The elastic bands 2 can be provided in a hemstitch, but can also only be placed on the blank 1 and welded to it. In the latter case, displacing the elastic band 2 is prevented by arranging a corresponding number of welding points 3 ^r. At the same time, a particularly cheap design of the garment is created, since the hemstitch is not produced and the cut can be kept correspondingly smaller.

The blank 1 can be made of natural or plastic. Furthermore, all should be called elastic band Elastically resilient parts should be understood for textile goods are suitable to achieve compliance. As textile goods for the application of the invention Process are suitable, all such goods are to be understood in the broadest sense, but the application is at Garments, in particular items of laundry, are particularly useful.

The advantages achieved with the invention exist in particular in that a piece of textile with attached elastic bands can be produced with a few operations.

The process is also suitable for fully automated production and therefore well suited for large series. Since, for example, clothing and especially laundry made of cellulose or The like. are thrown away after possibly one-time use, this results in goods that can be manufactured cheaply, which fully meets the stresses that normally occur.
