DEVICE FOR RELEASE BROKEN THREAD OF FLYER FRAME Russian patent published in 2014 - IPC D01H5/22 

FIELD: textiles, paper.

SUBSTANCE: device for release broken thread of flyer frame comprises a drawing device made of several drawing pairs, comprising corrugated cylinders, pressure rollers, and means for adjusting the arc of flow-around by the broken thread of the delivery roller made in the form of contact rollers and rolls with grooves located in their central part on working surfaces opposite each other. The rollers are mounted on the rod placed in the front part of the folding lever of load of the drawing device with the ability of reciprocating motion in it, at that the roll and the roller of the adjustment means of the arc of flow-around by the broken thread of the delivery roller are mounted with the ability to flow-around the roller by the yarn. According to the invention the rod is made T-shaped, on which horizontal branches the cylindrical rollers are fixed, coupled with the rolls mounted in a spring-loaded sleeve lugs, located on the vertical part of the T-shaped rod. The working surface of the rollers and the rolls is made of composite materials with a low coefficient of friction, which helps to reduce the friction of the broken thread on them. To move the T-shaped rod on the side surface of the folding lever of load of the drawing device, in its front part, a knob is mounted.

EFFECT: device enables to improve the yarn structure, to increase its strength, to improve its physical and mechanical properties and to increase the productivity of the flyer frame by reducing breakage.
