The invention also relates to a yarn treatment device in various senses or the gradation at which the portion of the yarn treatment is significantly shortened, whereby the pre-twisted yarn is easily and continuously obtained *

The present invention relates to a nonuniform twisted yarn, and more particularly to a nonuniform twisted yarn which is free from yarn irregularity, strain, looping, etc. having"

The process of making twisted yarn by means of the twisting process from fiber material, such as sun wool or other natural fibers or fibers as the different types of synthetic fibers is known

Many types of yarn twisting methods are known, namely the longitudinal twisting system that spinning caps eley st s Wing twisting system, the tier twisting or the »double twisting system, etc.

With regard to this yarn twisting process, nan im generally say that in the course of this process the twist aims to be at the narrow part of the

209817/1070

Concentrate yarn, where the pre-twist unrogol · = idle time increases because the distance of the twist (twisting portation) or the distance between the Twisting βtoil and dom expansion part is long

On the other hand, it is known to strengthen the torsion already threatened to twist yarns. But general will In each of these systems, the wound-up Kötzer is subjected to damping in a normal atmosphere or in the vacuum chamber with the Kötzer coil as it is.

therefore, the difference in attenuation occurs inevitably between the outer and the inner layer of the Kötzer yarn layer, which makes it difficult to use a uniform treatment results in · As a result, the outer layer can be over-treated if one of » sufficient damping of the inner layer, which has a lower treatment utilization «should take place, which is not only a deterioration in the quality of the fiber material, but also a number of so-called loop formation (snail generation) results. From this point of view, it is also difficult to obtain a non-uniform yarn reach.

Furthermore, in the case of the floor turning system, which the twist originates from the thread killer, even the grain of the kötzer "yarn" lying against the kötzer tends to twist in, so that the separation dee Games is bad And fiber-rich yarn can be produced, which is a deficiency «

Vie already briefly explained, according to the invention, the preliminary twisting device between the twisting part and the Arranged winding part of the yarn, preferably near the winding part and the distance between the twisting part and the winding part is shortened as much as possible to condense the twist in the narrow yarn part avoid. Thus, a twisted yarn with a small amount of twist irregularity can be produced and due to this device for the preliminary twist, the twist of the yarn between the Device for the preliminary twist and thickening of the yarn to close to zero or as little as possible can be reduced, the unwinding from the bobbin is improved and the twisted yarn is less Has grain, can be produced «

In the drawing described below, which shows an embodiment of the invention, in FIG. 2 the yarn 3 to be twisted eats up. The Kötzer 4 is wound up · This Kötzer 4 sits on a spindle 5 and turns in the direction of the arrow 6. 8 is a thread guide.

The yarn twisting bobbin Io is supported by the shaft 11 and is rotated in the direction of the arrow 12 by friction.

With the usual stage twisting systems, the twisted yarn is wound onto the bobbin through the gara guide « but in the invention the preliminary twisting device is arranged.

This device 13 for the provisional twisting temporarily holds the yarn between the device for the provisional twisting and the other part and can impress the condition of the provisional twist on the yarn for a certain time, this twist being increased or decreased in the twist and this or more than this Invention * is generated according to such a way that it can operate according to the destination, of course, no limit to the construction is present, the \ n the drawing is used shown "

guide and passed through the winding and in this case the device for the preliminary rotation is set in rotation to impress the rotation in such a way that it receives the same direction as the direction of the spindle and the same number of rotations as the number of spindle revolutions, then the desired twist number is impressed on the yarn in the short part between the device for the preliminary twisting and the flushing, so that the non-unevenly twisted yarn "which has neither twisting irregularities nor fibers according to the principle described above, can be obtained.

Furthermore, in the case of a non-twisted thread or a parallel-spun yarn, especially with parallel bobbins, if there is a separation or tangling of the thread or the parallel game due to the balloon-like

209817/1070

Magnification of the spindle is feared, the rotation of the Device door the preliminary twisting will be slightly less than the rotation of the Kötzerspindel dew yarn and the yarn a slight twist is also impressed between the thread curler and the device for the preliminary twisting, and the remaining number of twists can be between the device for the preliminary twisting and the purging *

The condition of the yarn during these twisting loops will now be explained with reference to the drawing «First will, as in Pig. 5 shown when the rotation of the device for preliminary twisting is in the same direction and with the same speed as the spindle, which runs the Yarn applied twist is reduced and after passing through the device for the preliminary twist, the .

If the rotation of the preliminary twisting device is decreased a little so that it is slower than that Rotation of the spindle 1st, as shown in Pig x 6, some twist is applied, and after passing the device for the preliminary rotation, that number of rotations is thereby 'impressed'. The remaining twist is imprinted on the gant in such a way that the pinned yarn with the pinned twist can be obtained on this

FIG. K shows the example in which the sheath 115 is attached to this spindle 5. Thereby, the goal of reducing the harmful tension of the threatening gara can be achieved with greater success is to omit the device for driving the device for preliminary twisting «

The twisting capability of the twisting yarn is a important problem for the production of non-uniform yarn, which is the aim of the invention. £ r according to the invention is the method of impressing the torsional reinforcement not taken over by steam treatment together with the Kötzer. This method was used even before the invention

According to the invention, the yarn as a whole is compared with that treated by the usual maneuvering front turning system Yarn, not damaged and has a very even, tight twist. This uniform © twisting * Consolidation is imprinted under very sensitive conditions and can still be carried out by a very small device will.

Xn of the preliminary twisting device is the The number of twisting relative to the threat number of the yarn is theoretically not limited at all, but at the practical design is sufficient to simply or twice the number of revolutions »

In the treatment device 2k , the yarn is heated by the treatment medium, for example steam, and immediately after passing through the device for the preliminary twist, the part of the twist increased due to the preliminary twist is quickly reduced to the number of twists on the yarn and it becomes then wound on the coil Io attached to the spool.

The state of the yarn in the preliminary twist described above is shown in Pig · Io and will be explained with reference thereto.

When the yarn 3 through the treatment device 24 over the tension coropensator 28 is performed, as by 3 d is shown, one to twice as much twist impressed with the cooperative use of heating due to the device 13 for the preliminary twisting in the Värmoaediuia located therein, and the yarn turns

at the same twist number as that of the yarn immediately after passing through the device 13 for preliminary pre-threading ffiuriiok. But in this case, the twist is strengthened by the preliminary increased twists given to the yarn when it was heated, whereby the generation of crimp caused by the decrease in twist can be prevented.

The quality can be improved with decreasing effectiveness by performing this twisting and twisting strengthening by interlocking operations .

In this case, for example, the twisting system by the rotating spindle of the Kötzers, which is twisted as is usual with the tier twisting system or the double twisting system, is used for twisting and the twisting yarn is subjected to a heat treatment in the treatment zone for twist strengthening between the pull roller device and the Aufspweln subjected, whereby the
