Description

one

The invention relates to the manufacture of fibers in the chemical industry and relates to a device for imparting a compactness to a moving yarn.

A device for this purpose is known, comprising a channel for a thread and a channel with a shut-off valve for air, made in a split housing consisting of two parts. To enter the thread in the working area, the device has a longitudinal slit 1.

The presence of a slot for insertion of a thread worsens the process of interlacing the filaments, which is associated with the ejection of individual filaments of the thread into the slot, which occurs when blown off with a stream of compressed air. In addition, in the presence of a filling slot, it is impossible to use channels for the passage of a thread of small diameters (01.0 / 1.2 mm).

These disadvantages are eliminated in the filament treatment device with a stream of compressed air, in which one of the body parts is rotatably installed relative to the other and there is a latch that serves to connect the body parts. When moving the rotatable part of the body, a gap is formed, which ensures the threading of the thread 2.

However, in this device, when turning parts of the body, the supply of compressed air continues, which worsens the process of threading.

The purpose of the invention is to increase reliability.

devices by reliable threading in the channel.

This is achieved in that the rotatable part of the housing is spring-loaded, and the latch is fixed on the shut-off valve.

FIG. 1 shows the proposed device, a general view; FIG. 2 shows a section along A-A in FIG. one; in fig. 3 is a section along BB in FIG. 2; in fig. 4 - section bb

The device for treating the thread with compressed air stream comprises a split case having a non-moving 1 and movable 2 parts mounted on axes 3 rotatably with respect to part 1. The case is rigidly connected to the nozzle 4. In the fixed and movable parts of the case, liners 5 and 6 that form channels for

threads. In the stationary part 1 of the housing, a channel 7 is provided for supplying compressed air with a shut-off valve 8 having a handle 9 on one center and a latch 10 on the other. H.J of the moving parts of the case have a finger 1. (

11- The moving parts of the body are pressed to the moving parts by a spring 12. H; t the body has two plates 13 and 14, which serve as guides for the turning parts of the body and carrying thread guides

15.

The device provides the processing of two threads and works as follows.

The threads pass through the axial channels formed in the liners 5 and 6. Compressed air through the nozzle 4 and channel 7 with a crane 8 goes to the liners 5, and through the holes in the axles 3 and the longitudinal holes in the rotary parts 2 of the body - to the liners 6 Through the radial openings of the 16 liners, air enters the channels for “air. The centering of the filaments in the channels is carried out by the guides 15.

Threads B The channels are threaded by turning the handle 9. In this case, the valve 8 blocks the air supply, and the latch 10, acting on the fingers AND, turns parts 2 of the housing on the axles 3. Between the inserts 5 and 6 there are gaps providing the threading. When the handle 9 is returned to its original position, the latch 10 releases the fingers AND, and under the action of the spring 12 the moving parts 2 of the body are pressed against the fixed part

1. With further rotation of the crane, compressed air is supplied to the channels for treating the threads,
