Description

BASIC Auth. St. No. 106123 describes a spinning machine for producing twisted, yarn using spinning, knitting and twisting in a single process, characterized by using. a hollow spindle carrying a yarn package, which is connected in the axial channel of the spindle pinch with the yarn coming from a stretcher, and twisted with it by means of a clamping device. This machine is also equipped with a shaft winder located under the spindles for cross or other winding of the twisted yarn into a reel.

The spinning machine described is a further improvement of this one, which makes it easier to maintain. This improvement is that the machine uses a roller with a roller installed under the auxiliary supply pair, as well as a folding yarn guide for arranging the thread with a cross hank, which simultaneously performs the function of an output chopper when one of the twisted threads breaks. The folding yarn guide is designed as a two-armed lever with a counterweight; the lever axis is fixed on the carrier bar, with the eye of the yarn feeder placed at one end of the lever, and the adjustable eyelet is placed on the other end of the lever, tilting the thread guide to the knife to cut the remaining thread when the other thread is cut and to be fed to fishing rollers.

In order to twist the thread and hold one of the broken threads in the spindle channel to enable threading on the machine, the latter used a centrifugal sliding clip mounted on the lower end, a spindle and made in the form of two plates, one of which was used as a tension device. strengthened under number 123438

Visionally, and the other, on the rotary axis, is pressed against the fixed plate, by centrifugal force.

FIG. 1 shows the torsional-motive part of the machine; in fig. 2 - spindle in section.

Hollow spindles .2 are fastened on the spindle bar ./, through the axial channel of which the straightening thread 3 passes, the outgoing needle of the extractor 4 passes. A reel 5 with yarn is mounted on the spindle of each spindle. At the lower end of the spindle spindle, a centrifugal sliding clamp 6 is mounted, clamping the thread to twist it during rotation of the spindle under the action of centrifugal force. The clamp is made in the form of two plates 7 and 5, one of which is fixed motionless, and the other on the rotatable axis and is pressed against the first by the action of centrifugal force. Brake 9 serves to stop the spindle.

A centrifugal node with clips is an auxiliary pair of rollers consisting of a metal corrugated cylinder 10 and rollers 11 pressed against it with an elastic coating. This pair serves to regulate the tension of the straightening yarn 3 in the area from the exhaust device 4 to the lower end of the spindle. Regulation is made by changing the speed of the auxiliary pair. Under the latter, there is installed a cylinder-12 with rollers 13, as well as a folding yarn guide 14 and a knurling roller 15, which rotates the reels 16 with a wound twisted thread. To trim one of the twisted yarns when the other yarn is broken, the yarn guide is made in the form of a two-armed lever, swiveling around an axis 17 fixed to the slat 18 of the drive. At one end of the lever, the eye of the yarn feeder is attached, and at the other end there is a weight 19, which pivots the eye with the thread to the knife 20. The reel 16 is mounted on a holder 21 moving in a guide 22 that can turn forward on the axis 23 during the removal of the reels. The guide 22 is held in the working position by the leaf spring 24. The spinning thread 3, passing through the axial channel of the spindle 2 and clamped by the centrifugal clamp 6, is twisted with another thread, unwound from the reel 5. Pass through the auxiliary pair, cylinder 10 and roller 11, the twisted thread is wound into a reel 16 cross-wound using the eye of the yarn feeder 14, reciprocatingly moved by the bar 18. In the case of a break of one of the twisted threads, the other thread is automatically cut by the knife 20, to which it presses Rotne eyelet lever by means of the sinker 19, the turning lever when loosening the tension thread, inevitable in the case of the other yarn breakage.

Subject invention

Claims (3)

1. Spindle-twisting machine for producing twisted yarn using spinning, chipping and twisting in a single process according to ed. St. No. 106123, characterized in that, in order to improve serviceability, it uses a cylinder with a roller, installed under the auxiliary, feed pair, as well as a folding yarn guide for laying out the thread with a cross reeling, which simultaneously breakage of one of the twisted threads. 2. The machine according to claim 1, characterized in that the folding yarn guide is made in the form of a two-armed lever with a counterweight, the axis of which is fixed to the slat bar, and at one end is placed the eye of the yarn feeder, and on the other - an adjustable weight, folding the yarn guide to the knife trimming the remaining thread and supplying it to curing rollers when one of the threads breaks. 3. The machine according to claim 1, characterized in that, in order to twist the thread and hold one of the broken threads in the spindle channel, which makes it possible to thread the thread on the machine, the centrifugal slide is used as a tension device; a clamp mounted on the lower end of the spindle and made in the form of two plates, one of which is fixed motionless, and the other on the rotary axis and pressed against the fixed plate with help of centrifugal force.
