" Process and Eiririoh.tu.ng for crimping continuous tow or material "

The invention relates to a method and a device for crimping continuous thread material or laser material, but in particular to a device which gives the fibers a stable and homogeneous crimp.

It has been proven that the effectiveness of a crimper determines the quality of the crimped material. It is essential to have suitable pre-treatments

provided so that the material to be fed in its Density "remains constant" and before its introduction into the The crimping process is kept evenly aligned. G-suitable measures, e.g. heat treatment, must can be used to hold the curled material in place. It is equally important to have the processed material under to maintain an optimal and even tension, to adapt the end product to the specified Ensure quality.

The invention relates to the installation of these tools in a crimping machine as well as its combination with a crimping machine, to the work material at a desired and controlled speed to pucker and to keep the puckering free from irregularities.

The invention is primarily to provide creation a method and a device for supplying evenly separated aligned continuous. Thread material or fiber material at a controlled speed in a frilled chamber to make it up to the desired To curl extent with high accuracy and efficiency.

Another object of the invention is the creation of Means for continuously fixing the crimped Materials by means of a heat treatment in order to "prevent any change in quality.

Finally, the invention relates to a novel one

This V-shaped structure is expediently designed so that its angle can be adjusted.

Between the first two guides 9 and 9 'are two rollers 10 and 10 arranged vertically one above the other. attached, of which the upper leads the strand P and the arranged underneath is immersed in a chemical solution contained in the container 6 as it circulates.

The strand F is inserted through the guide 9 at the entrance ■ of the chamber 5, where it unfolds, arranges and neatly aligns. When the material then runs over the guide roller which is in contact with the wetting roller 10 *, it is wetted with a chemical solution which is used to equip it for curling and at the same time to facilitate its separation or division in the course of the subsequent processing operations. The strand F then runs through the intermediate guide 9 ', where its alignment is further improved, and finally arrives at the steering guide 9 ^fl which is arranged parallel to the guide 9'. As shown in Figure 4, the control guide is 9 *. ' Constructed in the shape of a "V", the angle of which can be adjusted »to allow the thread density to be changed in the steam chamber in order to adapt it to the working conditions of the crimping device.

so that a suitable pressure is constantly exerted on the work item. Another adjustable weight 23 is .A pressing device 24 assigned, which, at 25 to the Articulated machine frame, sitting at the end of the second crimping zone forming a continuation of the first zone.

After the strand F has passed through the zone 1, it enters the crimping chamber 2 described above. It is introduced into the guide trough 16 by the two feed or delivery rollers 11 and 11 '. As it passes on the bottom of the trough 16, it is compressed by the pressure plate 13 to a predetermined extent, ie to an extent conducive to the degree of curling . The degree of curling caused by the press plate 13 is insufficient. The material is therefore brought into contact with the outer circumference of the crimping wheel 17, where it is subject to sufficient crimping forces and takes on a fine crimp. The degree of curling of the material can be regulated as desired by the weight 22. Since the curling wheel according to the invention is carefully designed, there is no risk of the material becoming tangled or irregularly curled. ^{The material I 1} crimped in this way now goes into the next crimping zone, where it is kept compact by the vertically adjustable pressing device 24 to such an extent that the crimping shape created by the crimping wheel 17 is maintained.

The crimped material is now in the fixing zone 3 introduced. According to FIGS. 6 and 7, the fixing section contains

The fixing zone 3 is built completely airtight in order to ensure that a desired constant temperature and humidity are maintained in the chamber, as is essential for achieving uniform and complete fixing of the crimped material. /
