Abstract

Usage: textile industry, rotor pneumomechanical spinning. SUMMARY OF THE INVENTION: the device comprises a drive dope rotor, the axis of rotation of which is perpendicular to the axis of rotation of the comb roller. A friction element is fixed at the end of the combing roller to communicate another false twist, made in the form of a body of revolution and capable of point contact with the yarn exiting from the guide channel of the sleeve. The sleeve is mounted close to the yarn funnel mounted coaxially with the spinning rotor. The guide channel is inclined relative to the end of the comb roller in the opposite direction from it. The frictional element is in point contact with the yarn at a distance from the guide spacer in the form of a tube not exceeding the average fiber length of the yarn. 1 s.p. f-ly, 3 ill. WITH

Description

The invention relates to the textile industry and relates to an apparatus for rotor pneumomechanical spinning.

The purpose of the invention is to increase the productivity of a device without increasing energy costs.

In Fig.1 shows a device in section; figure 2 is a view of figure 1; Fig. 3 shows the position of the spokesman at the time of piecing.

The device comprises a drive dope rotor 1 and a coaxial funnel 2 installed coaxially with it. At the outlet of the coarse funnel 2 there is a sleeve 3 with a channel 4 adjacent to the outlet of the chewing funnel 2. The outlet of the channel 4 is located above the end of the comb roller 5. On the end of the comb roller 5 has a means for communicating another false twist, which is a friction element in the form of a ring 6 or another body of revolution made, for example, of rubber, polyurethane and the like Container material. Ring 6 is installed on the end of the comb roller with the possibility of replacement when worn. The rectifier 7 is mounted in the direction of movement of the yarn 8 to a winding unit (not shown) and is made in the form of a tube 4 with the possibility of movement and supply to the channel 4 of the sleeve 3 by known means, for example, a mechanical system with pneumatic or electric drive.

The axis of rotation of the comb roller 5 is perpendicular to the axis of rotation of the spinning rotor.

The device operates as follows.

The yarn 8 formed in the spinning rotor 1 is withdrawn from it through the yarn funnel 2, the spindle guide 7 and wound onto a bobbin. When yarn 8 passes through the channel 4 of the sleeve 3, the yarn rises above the means for reporting a false twist and, under the action of the spindle 7, contacts the ring 6 at point B (Fig. 2). The lower end of the thread guide 7 is located from the contact point B of the yarn 8 with the ring 6 at a distance not exceeding the average length of the fibers and yarn, which helps to reduce the breakage of the yarn. The rotary ring 6 imparts another false twist, a part of which (of the same direction as the twist direction) extends towards the spinning rotor 1. to increase the twist of the yarn forming portion in the rotor. Due to this, the yarn forming section is hardened, which allows yarn to be produced with a lower filling twist, thereby increasing the productivity of the device.

In order to carry out the bending, it is necessary that the yarn guide is in the position of connection with the channel A of the sleeve 3, the measuring end of the yarn is threaded into the yoke 7. And, in a known manner, the spinning rotor is powered by the fibrous product. Executive Director with the help of the known means

The movement deviates to the operating position. At this time, the process resumes, and yarn 8 is in contact with the means for reporting false

twists.

This device has a simple design while ensuring false yarn torsion efficiency and thereby improves productivity.

The claims

Claims (2)

1. A device for rotary pneumomechanical gear containing a drive dope rotor with a yarn outlet funnel located coaxially with it side of the end of the comb roller mounted with its axis of rotation perpendicular to the axis of rotation of the spinning rotor, and a sleeve fixed to the guide channel communicating with the funnel from the outlet of the yarn from the funnel, the outlet opening of which is located at a distance from the end of the comb roller distinguishing it by the fact that, in order to increase performance without increasing energy consumption, it contains a friction element in the form of a body of revolution, mounted on the end of the comb roller with the possibility of contact with the yarn exiting from the guide channel to inform her of a false twist in the direction of its actual twist. 2. The device according to claim 1, characterized in that it a comprises a tubular spacer installed with the possibility of supplying its end to the outlet of the guide channel of the sleeve.
