Description

Sw

This invention relates to the textile industry and relates to spinning equipment.

The aim of the invention is to improve the operation efficiency by ensuring that the tension of the thread is equalized as it descends from the spad on the spindle of the balloon limiter.

FIG. 1 shows a general diagram of a spinning machine; in fig. 2 is a view A of FIG. one; in fig. 3 view B in FIG. one.

A device for tensioning yarn 1 converging from the cob 2 on the polo spindle 3 of the spindle of the spinning machine comprises a ring 4 fixedly mounted in the upper part of the spindle 3 of the spindle between its top 5 and the installation zone of the cartridge 6 of the cob 2.

The ring 4 is mounted coaxially with the spindle 3 and with a gap relative to the outer surface of the spindle. The inner diameter of the ring is smaller than the outer diameter of the upper part 7 of the chuck 6,

Ring D is made of a rod 8 bent circumferentially in the direction of rotation of the spindle 3 spindles and having a straight line section 9 located tangentially relative to the bent part to form a slit 10, and fixed, in the holder 11, the thread conductor 12 for the thread 13 coming out of 14.

The fixture attachment to the holder 11 is carried out by means of a screw 15, a nut 16 and a washer 17.

Prt-device works as follows.

Along the cob 2 thread 1, bending around ring 4, enters i hollow spindle 3 BepeTeHaj where it is twisted with the center thread 13. Ring 4 provides the angle of bending around the thread of top 5 of spindle 3, the angle between thread 1 and 13 in front their combination and twisting, which improves the quality of the twisted yarn.

The tension of the thread 1 before it enters the hollow spindle depends on its tension in the balloon under the ring and on the amount of additional tension created by the ring.

The fixture creates additional tension due to the fact that

thread 1, bending the ring 4 and the top 5 of the spindle 3 spindles, is experiencing additional resistance to its linear movement. The amount of additional tension on the thread 1 is maximum at the beginning of winding it off the cob, when the diameter of the balloon under the ring is maximum, and the length, weight and tension of the thread in the balloon are minimal. As the thread 1 is squeezed from the cob 2, the diameter of the cylinder decreases, the length, mass and tension of the thread in the cylinder increase, while reducing the amount of additional tension on the thread compared to working without adjustment. FIG. 1 one of the positions of the thread 1 at the beginning of the cob activation is shown by a solid line-, and at the end of the operation by a dashed line.

Reducing the amount of additional tension on the thread as the cob activates compared to working without a device is due to the fact that the difference in the thread bending angles of the spindle tip with and without the device gradually decreases, approaching zero at the end of the cob act, and the bending angle decreases thread of the ring, also approaching zero. Reducing the amount of additional tension of the thread as the cob activates while simultaneously increasing the tension of the thread in the balloon allows the tension of the thread to become more uniform as it enters the hollow spindle and improves the quality of the twisted yarn.

The use of the device does not increase the time spent filling the yarn 1 into the ring 4 while eliminating its breakage, because when winding the yarn 1 off the cob 2, due to the rotation in the direction of rotation, the spindle itself enters through the slit 10 into the ring 4.

When the cartridge 6 is removed from the spindle spindle, the cartridge hits the ring 4 which, together with the thread guide 12 and the holder 11, leans towards the exhaust device 14.

Fluffing of the ring from fluff is produced by the air flow arising from the rotation of the cob and the thread -1 as it moves along the ring.

The adaptation allows to improve the quality of the twisted yarn by ensuring the constancy of the angle at which the twisted yarns join, and by equalizing the tension of the yarn coming down from the spad on the spindle. The use of the device, in addition, helps to eliminate 12 such defects of the twisted yarn, as sugars and a single thread. . The device has a flexible design and does not require time for its cleaning and threading it.
