Abstract

The invention provides a process, a device and a textile sheet-like structure, the process for producing the textile sheet-like structure residing essentially in that a plurality of tangled threads is fed to a sewing station, and the tangled threads fed to this sewing station in free fall are secured in the region of the sewing station by means of the sewing thread.

"Process for the production of a textile fabric"

The invention relates to a method for the production of a textile fabric according to Art a stitch-knitted fabric in which a tangled thread falls freely are fed to the sewing point and wales are knitted into the random thread.

In DE-AS 24 2o 612 a method for producing a stitch-knitted fabric is described in which on a prepared base fabric a thread sheet on qc-lctjt that of the basic goods with a feed speed is fed that is higher than the take-off speed the basic commodity is, whereby in the basic commodity Wales are knitted, which the Connect the thread sheet of the basic fabric, as a thread sheet Pattern threads are provided which, as single threads, create a pattern effect after leaving the delivery device bypassed leaving itself placed on the basic goods and so with this get connected. The so-called pattern threads are fed in freely falling. Through this it is achieved that an 'arbitrary surface patterning is created as the freifa I loins Pattern threads are unguided and uncontrolled on the Place basic goods. Such a procedure is special suitable for curtains or the like.

It is crucial in the known method that the free-falling pattern threads on a regularly formed Basic goods are launched, and continue to

the pattern threads are also only intended as effect threads. From DD-PS 3o 447 is a method for Manufacture of a stitch-knitted fabric has become known in which the basic fabric is CheniI threads and fancy yarns are placed, which the basic goods with a Feed speed higher than is the withdrawal speed of the basic goods. The feed takes place in funnel-shaped thread guides and The thread sheet is vibrated in the funnel shape igen thread guides so compacted that an imitation of fur is created. A basic product is also required here, to which the thread sheet is applied.

This is the case in some areas of technology Need a textile fabric as a support or Use reinforcement fabric, in which the this textile fabric forming threads in are not arranged in a regular manner, but rather the threads should stretch in all directions in order to increase the strength of the fabric, namely the tensile strength and thus at the same time the compressive strength of the fabric in all directions to train equally strong.

5 The production of such a fabric was previously only possible by hand and therefore for very limited areas of application limited.

The invention is based on the object of t e χ tiles To create flat structures in which the the threads forming the textile fabric in all Directions extend irregularly.

This object on which the invention is based is achieved by the procedure according to the characterizing part

of the main claim solved.

The fact that the tangled threads fall freely at a sewing point are supplied, i.e. not on a basic product are placed, the tangled threads form the actual textile fabric after being sewn and the individual thread sections of the tangled threads extend in all directions so that in The same tensile and compressive strength of the textile fabric is achieved in all these directions.

The textile fabric produced in this way can directly can be used as an end product. It is but also possible, this textile fabric to soak with active ingredients and finally it is possible to use this textile fabric as a coating carrier to use, on which then additional broom materials are applied and laid down are, for example glued, sewn or the like.

An embodiment for the implementation of the invention The method is explained below with reference to the drawing. The drawing shows i η

25th

Fig. 1 is a schematic section through a for the production of the textile fabric suitable device and in Fig. 2 is a plan view of a textile Sheetlike structure according to the invention

was achieved.

In Fig. 1, a material supply can be seen, for example a bobbin from which a random thread 2 of corresponding Feed rollers 3 with the interposition of

Revolving rollers 4 removed and the actual sewing point is fed freely falling. The tangled thread 2 is fed into a funnel-shaped feed device 5 and preferably on a feed plate 6

filed. In the feed device 5 can im Effective feed aids provided at the bottom of the funnel which are not shown in the drawing.

With a sewing thread is designated / that of the sewing point is fed, i.e. a punch needle that can be seen at 8 and at 9 recognizable compound needle, via a The take-off roller 1o is then formed and solidified textile fabric 11 peeled off.

In the illustration in FIG. 2, the random threads can be seen at 2 and the sewing threads at 7, whereby from the illustration in Fig. 2 it can also be seen that the Sewing threads run in a zag shape, i.e. the sewing threads are in the plane of the textile fabric 11 arranged side by side in a zigzag shape, whereby the solidification of the textile surface structure Ides 11 takes place.

From FIGS. 1 and 2 it can also be seen that the previously required basic goods are no longer provided is, i.e., the transverse thread system still provided in the device according to DE-AS 24 2o 612 no longer used, but the textile fabric consists exclusively of the tangled thread and the sewing thread, whereby the tangled threads are solidified by the sewing thread.
