Equipment includes twin-twist adjustment machine that consists of an arrangement adjustable sliding rollers (Θ) between conductors (6, 7) and auxiliary pulley (9) Then it is between the auxiliary pulley (9) and placed by the shearing roller (10) device (12) controlled by sensors. Processed silk! for example, it can serve as a sewing machine threads.

Description

The invention relates to an apparatus for processing synthetic silk on a double-twisting twisting machine.

3e shows a known method of processing synthetic air-shaped silk, where in the first operation a basic twist is given, then in the next operation a joint winding of two or more silks on one spool follows, which serves as a template for another twisting operation where so-called twisting which has the opposite meaning to the basic twist.

When spinning from a combined spool, the spun single yarn is usually transferred to cross yarn bodies on a cross winding machine. Two or more single silks are then twisted on a satellite machine and wound in a parallel position without twisting on a cross spool. When winding two single silks together, it is necessary to ensure that all the silks are wound completely parallel without loops and with exactly the same tension. If these requirements are not met, defects will occur during the actual twisting, or during the heat treatment of the chopped material, for example during dyeing, fixing and the like, various precipitation of individual threads and formation of loops and similar defects will occur. The combination of synthetic silk, especially air-shaped or otherwise, is a very difficult operation, as this material is not easy to unwind from the two master spools and has a very strong tendency to form loops. In order to make the joining operation economical, high speeds are used, which can cause the individual fibers of the synthetic material to melt and thus impair overall properties, such as strength, smoothness or sewing ability, especially in fine species.

The disadvantage of this method of processing synthetic silk is the need for a separate blending operation with all the original costs, such as investment in a satellite machine, large built-up space, greater labor requirements, high energy consumption and extended cycle life.

The object of this disadvantage is to eliminate the method of processing synthetic silk according to the invention, the essence of which consists in that air-shaped silk is individually given a basic twist and at the same time in one operation for further processing - scanning.

The essence of the device for carrying out the method of processing synthetic silk according to the invention, which comprises a twist twisting spindle with twisting wing, conductors, auxiliary pulley and winding device, consists in arranging horizontally adjustable pulley between conductors and auxiliary pulley to adjust the angle of silk wrap in between the auxiliary pulley and the take-off roller, a sensor-controlled cutting device is arranged to break one silk in the event of a break in the other.

This combination of two operations into one allows the use of a modified twist twisting machine for joining, and thus it is possible to omit this operation on a specially focused machine. .

This saves costs on these machines, there is no need for a built-up area with these machines, the number of operators is reduced, and energy consumption is reduced. Furthermore, a precise association of the output coils was achieved without the occurrence of the defects described above.

The essence of the invention is shown in more detail in the figure, where a schematically modified two-twist twisting machine is performed.

The first silk J. and the second silk 2 are wound on masters 3. The masters 3 are mounted on a hollow spindle 4 located on the machine frame. The twisting spindle 4 is provided with a wing 5. The first conductor 6 and the second conductor 7 are mounted above the twisting spindles 4. The conductors G and 7 are arranged fixedly. A horizontally adjustable sliding roller 8 is arranged between the guides 6,7 and the auxiliary roller 9 to adjust the angle of wrapping of the silk 1, 2 in the guides 6 and 7. Above the auxiliary roller 9 there is a take-off roller 10. Between the auxiliary roller 9 and the take-off roller 10 placed electromagnetic shear device 12. However, shear device 12

CS 276 484 B6 2 can be made by any known cutting element. The cutting device is connected to the left sensor 13 and the right sensor 14 and is controlled by them, the sensors 13, 14 are located in the paths of the silk process jL, 2. In case of breakage of the first silk. 2. In the event of a break in the second silk 2, the cutting device 12 closes the right sensor 14 and breaks the first silk. The sensors 13, 14 can be implemented in any known manner, such as contact or contactless and the like. Arranged above the distribution roller 10 is a distribution device (not shown) for winding the silk 1, 2 onto the superimposed spool 11.

The function of the device is as follows

The first silk 11 and the second silk 2 unwound from the spools 3 pass through the center of the twisting spindles 4 and after passing through the wing 5 I proceed to the first conductor 6 and the second conductor 7. In doing so, the silk is given a basic twist. From the conductors 6, 7 the silk 1 and 2 goes to a sliding roller 8, which can be adjusted horizontally between the conductors 6, 7. Further ^{in the} space between the auxiliary roller 9 and the take-up roller 10, the silk JL, 2 passes through the superior spool 11 by an electromagnetic shearing device 12, which is controlled by a left sensor 13 and a right sensor 14, which follow the path of the first silk JL and the second silk 2.

During operation, the required voltage is generated by a suitable choice of kinetic conditions. The same tension of the silk community JL, 2 is achieved by setting the sliding pulley 8 closer to the first conductor 6 or to the second conductor 7, thus changing the circumference of the conductors 6 and 7 with silk JL and 2, which causes a change in their braking. When the first silk 1 breaks, the left sensor 13 causes the second silk 2 to break by means of the cutting device 12. When the second silk 2 breaks, the right sensor 14 causes the first silk 2 to break.

The described device was used in the processing of air-formed polyester silk threads. The exact superimposition of the output superimposed coils 11 is achieved without the occurrence of the described defects. In addition to increasing the quality and reducing waste, manpower and costs for a separate technological operation of the association were saved.

Synthetic silk treated in this way can be used, for example, as sewing thread.
