(Removed from patent. ... ... (patent application D 41 054 VIIa / 41d)

The invention relates to a device for producing zen.

According to the invention there is a device for producing a Mushrooms from bodies with which one or more webs of synthetic textile thread, which in a strand with desired The width can be summarized from a number of parall len rollers around which the strand is guided in a sinusoidal path from heating devices in a relaxation zone, which allows the synthetic textile thread to relax in a curled state and to form a mat from pädens, and from devices by which this mat is sewn through with barb needles.

Synthetic textile thread ί- ^η can be combined into a strand, can consist of a number of parallel cross rods which are arranged side by side and are carried on two parallel support posts which extend transversely to the cross rods, one at each end thereof. Preferably, the cross rods are arranged in a substantially perpendicular plane to that of the web or webs of synthetic textile thread to be combined in a strand.

The supports on which the cross rods are carried can do so be appropriate that they can rotate about a line connecting their centers, and so the angle between the Cross rods and the or the lanes of threads, which are to be combined into a strand, on any desired Value can be set. The tension applied to the threads depends on the angle between the cross rods and the or the webs of threads, and so by applying the supports can be rotated about a line connecting their centers »Tensions to be applied to the threads to the desired value can be set.

Parallel rollers are close to the facilities for. Combining the threads into one strand is provided. The strand becomes sinusoidal Web passed over these rollers, which are preferably equipped with external, adjustable flanges that the The width of the strand can increase in a controlled manner while the strand is guided over the rollers »In general

at least 6 rollers or rollers are provided, these Rollers serve to pull the threads from a warp beam through the bodies to pull the threads together in one strand. .-- "■■■■".

i: the; Device can also support facilities

.-Judas ;: Unfolding the strand should be provided before this through a relaxation zone is performed in which the threads in a

can relax the puckered state. The preparation devices can consist of a curved opener, e.g. a rod or a curved roller. By adjusting the dimensions this conditioner and the relative height of the conditioner can a uniform thickness distribution of the threads across the width of the resulting fungus can be achieved. It's a relaxation zone provided in which the synthetic textile threads, which are usually present continuously, in a crimped state relax and mingle with each other. These threads enter the relaxation zone at a greater speed supplied as that with which the resulting mat is withdrawn from the relaxation zone, and the ratio of this speed is usually between 5: 1 to 5: 1. The continuous filaments can be crimped before being wound onto bobbins, from which they are pulled off under tension on the device, or the threads can also optionally by suitable means crimped between the bobbins and the device prior to being gathered into a strand. The threads can e.g. be guided in the form of a web over a knife edge.

Heating devices are provided in the relaxation zone so that the crimp in the fibers is fully developed, thus good Mixing results among the threads can be obtained. The heating devices preferably do not and can not touch the threads consist of a series of infrared heaters, high frequency heating elements or a hot air flow. The mat off

The barb needles 17 are carried by a needle head 18 which performs an oscillating movement can, whereby the barb needles'17 through the openings 16 are guided in the needle plate 15. Two rollers 19 and 20 are for pulling the mat from interlocking continuous Threads are provided under the needle head 18.

When applying the method, the device will have two tracks 21 and 22 from continuous chemical threads 23 from warp beams in a sinusoidal path over the cross rods 2 of the control device 1 drawn * The continuous threads 23 are crimped into the webs 21 and 22 before being brought together and into the webs 21 and 22 held under tension, thereby holding them essentially in place next to one another. The control device 1 brings the continuous threads 23 together in a rope 24 which is guided over the rollers 8 and 9 in a sinusoidal path will. The rope 24 can widen during the passage over the rollers 8 and 9 and widens due to the arched Bar 10 even further. The continuous threads 23 can then relax in the relaxation zone and form one Mat 25 of intermingling, interlocking, crimped threads. You leave the threads; 2J; -de: p; _; completely ruffled
