Method and device | \ in equipping web * or knitted fabric

The invention relates to methods and apparatus for finishing woven or knitted goods, in particular curtains made of synthetic material.

The equipping of this product was previously of special, for it established business operations. In the preparation of for curtains made of synthetic material, untwisted or low-twisted threads were used with the As a result, they had a different gloss and therefore had to be matted. In addition, it was necessary-

borrowed to dye and finish the threads in order to to achieve the necessary grip.

The woven, veined, knitted raw material is usually the Equipment businesses are delivered, which carry out the equipment and the finished goods back to the weaver or postpone the workman or sell it on his own account.

This of course results in considerable costs, which have a very expensive effect on the production of goods.

With the invention, the task is set, a substantial cost saving with a substantial shortening of the machining process bring about. Surprisingly, this difficult task can be achieved in that one used consisting of spinneret-dyed and optionally matted threads, which immediately after the Weaving or knitting process and preferably heat-set on the loom or knitting loom.

The basic idea of the invention is therefore that the finishing work in the weaver's business, or active agent is made. This change in production only has a chance of success if the .. The fixing process according to the invention does not represent a particular burden for the business operations of the weaver or knitter "

- 3 This condition is thereby achieved in the sense of the invention

fills that spun-dyed threads are used to produce the woven fabric. These threads are especially useful for the curtain production already the right color «you ' can also be supplied with a matt finish. It would also be possible, such threads with a much higher Use twist as normal, which breaks the sheen of the untwisted thread and the twisted thread like this looks like it's matted.

In the context of an advantageous embodiment, the invention provides that one of the guide rails of the Loom or knitting loom with the greatest possible looping around a heated one with needle rings Fuser roller leads. The heat setting in the sense the invention at temperatures of the order of 60 ° to 150 ° C, preferably 100 ° to 120 ° C, performed will. If one takes higher turned ones within the meaning of the invention Threads, the use of threads with twists in the order of 700 to 900 twists / m is recommended.

However, the subject matter of the invention is also a method according to which the VQm loom or knitting loom comes before fixing with organically dispersed finishing liquid "in the spray process is wetted from below or from both sides and is primarily guided through foam rubber blanks or the like, whereby the threads of the goods do not need to be spinneret-dyed.

In this case too, the weaving mill's business operations ■ or warp knitting enabled to make the finishing independently, although it is advisable to do this Liquid treatment not to be carried out directly in the loom or knitting loom but within a separate device, because you can run this machine much faster than the loom or knitting loom and thus with it «Achieves a significantly greater performance with a minimum of effort.

A suitable device for performing the input mentioned method according to the invention consists in that at the outlet of the loom or knitting loom, a heatable fixing roller with adjustable needle roller rings as well Deflection shafts are mounted on the fixing roller to form a sufficiently large wrap around the goods. This facility can be part of the loom or knitting loom. But it is also possible to use this arrangement as an independent modular unit easy to attach to a loom or knitting chair.

If the other inventive. Procedure with liquid treatment is carried out, a special machine frame is recommended as the device for this purpose, which is preferably is independent of the loom or knitting loom and in which there is a spray device for organically dispersed in front of the fixing roller Finishing means is arranged with at least one squeegee roller. .

In the drawing, the invention is schematic and example shown. Show it:

1: a schematic side view of a dry fixing device and

FIG. 2: a schematic side view of a variant of FIG Fixing device with spray device for equipment. - '■ - ■■■ ·'

In the embodiment of FIG. 1, it is assumed that the machine frame 1 is a part of the loom or knitting loom or can be attached to the loom or knitting loom as an independent frame. The subtree is on this frame 1 2 stored, of which the goods 3 via transfer shafts 4- a thermosetting roller 5 is fed. The transfer shafts 4- are arranged so that the TJmschlingwinkel the fabric 3 on the fixing roller 5 is the appropriate size. It goes without saying that the representation in Fig. 1 is only schematic and with the subtree 2 is only indicated that at this point the goods come from the loom or knitting loom.

The thermosetting roller 5 has needle roller rings 6, which axially should be adjustable so that the needle roller and cage assemblies 6 can capture the edges of the raw material true to size and is thus able to stretch the goods over with perfect transverse tension bring the fixing roller 5 away. The fixed goods will wound on the tree 7.

The thermosetting roller 5 is preferably electrical from the inside heated and controlled by thermostats. With the relatively long contact that the goods have with this roller, the Fixing temperature can be relatively low, so that too. Standstills do not bring about any change in the goods. the The temperature should be able to be set according to the thickness of the fabric from design to design. The needle roller and cage assemblies 6 should in addition, be such that the incoming goods, themselves independently needled and unthreaded. Since the goods, -preferably Curtain, at this point in time has its full raw width, no tensioning process is necessary, so that the needles 6 only have the Their task is to prevent the curtain from shrinking in width when it is heated.

In this way you can achieve a very good straight shot and true-to-shape product image. The goods that have been heat-set by this practical ironing effect also receive a Handle reinforcement. The spinning oils on the goods represent the antistatic agent. * There is no drive for the fixing roller 5 required, because the tension of the tree 7, the fixing roller 5 is entrained by friction. Of course— However, a special drive can also be provided in certain cases.

Do the operating conditions require additional liquid treatment with chemicals, e.g. dyes or finishing materials, then a spray device can be installed in front of the thermosetting roller 5

arrange. The liquid is evenly distributed by the subsequent nip rollers 10, which are preferably made of foam plastic or foam rubber, before the goods are subjected to the heat treatment.

In the exemplary embodiment of FIg. 2 Another case is shown that the goods 3 should not only be dry thermoset, but that they should also be provided with a finishing liquid, for example in the event that a special finishing, coloring and / or matting is to be carried out. For this purpose, the invention provides for the equipment liquid to be applied to the goods 3 with the aid of spray devices 9, the liquid being supposed to be organically dispersed. The liquid can be sprayed from below or from both sides while it is to spray not commend ^ the goods from above. Subsequent to the spray can by means of the squeeze roller 10 be made a uniform distribution of the Ausrustungsflussigkeit on the product which then rwalze on the Fxxx & 5 in the manner described leads overall is. the Maschinepgestell 8 is formed in this embodiment, preferably automatically, because it is recommended to leave this device to run as the Web or active seat faster. it can therefore be the next several Web or knitting frames product by a single equipment apparatus of FIG. 2 feed. Since preferably Organically dispersed * liquids are used, a closed design is recommended se the

It is thus apparent that the invention can be carried out in various ways, which is why the invention not limited to the illustrated embodiments.
