Description

The proposed machine aims to achieve the same circumferential speed on the surface of the coil during the entire period of winding of the reel arm, resulting in a uniform twist.s

In FIG. 1 is a front view of the machine; FIG. 2 is a side view.

For the proposed spinning machine, the flyer is replaced by a frame 4 with a lid 8 hinged at the hinge 7. on shchpuli 11. On axle 5 a sleeve 12 is put on, having a separate drive from a stepped jaw 13. Sleeve 12 carries a friction roller 14 in contact with two rubber rollers 17 mounted on sleeve 16 supported by pads 15, which are loosely mounted on sleeve 12. Rollers 17 participate simultaneously in two movements: around the axis of rotation of the frame 4 and around its axes, due to different speeds of the sleeve 12 and the frame 4. To the sleeve of one of the rollers 17 is attached a finger 27, turning a sprocket 26 by one tooth after each rotation of the roller 17. Sprocket 26 sits freely on axis 5 and connected to cam 24, which results in an oscillatory motion

The yarn guide 23 is spring-loaded with a spring 25 and fastened to the bar 22,. also participating in the rotation with the frame 4. Rollers 18 pass through the sleeves of the rollers 17, which are spring-loaded springs 20, which, while rotating together with the rollers, can move along its axis. The rollers 18 carry rubber rollers 19, which frictionally couple to the disks 10 and serve to rotate the coils around their axes. As the yarn is wound onto the coils, the rollers are pressed from the axis of the discs to the trans. rifery, and thereby decreases the speed of the coils. If there is one person, then the spool P is put, one, as shown by the dotted line.

The subject of the patent.

1. A spinning machine, characterized by the fact that sleeve 12, sitting freely on a hollow axis 5, is used to bring the frame 4 with the coils, which sleeve 12 carries a stepped one at one end, to uniformly wind the thread on the spools. and at the other end there is a friction roller 14 and a free foot 15 with two rollers 17 frictionally coupled to roller 14 and connected to fingers 27 serving to turn the rollers 17 around their axes on each tooth for each turn of the sprocket 26, which sits freely on hollow axis 5 and fastened oh with a cam 24 intended to vibrate the yarn feeder 23 rotatably attached to the bar 22, in turn, connected to the frame 4. 2. For the machine described in paragraph 1, the use of a tool for communicating a uniform twist straight rotation of the coils around their axes, consisting of rollers 18, passing through rollers 17 and through

the wall of the frame 4 and the supporting friction rollers 19, the rotating disks 10 and the diameter moved away from the axis of the disks of the wound yarn as the diameter increases, the rollers, for pressing which rollers 18 to the surface of the rollers serve springs 20 attached to them.

3. At the machine described in paragraphs 1 and 2, use the hinged cover 8, pivotally connected to frame 4 and serving as a bearing for the roller 9 supporting the coil with yarn during operation of the machine.
