DEVICE FOR CONTROL OF BREAKAGE OR ABSENCE OF THREAD WHEN KNITTING ON CIRCULAR KNITTING MACHINE Russian patent published in 2014 - IPC D04B35/00 D04B35/14 

FIELD: textiles, paper.

SUBSTANCE: device for control of breakage or absence of thread when knitting on a knitting machine comprises two fixedly mounted thread guides, the inlet and outlet, with holes for the thread, the thread tensioner located between them and the sensor of thread control made in the form of two-armed rotary lever which one lever in the working position interacts with the thread, and the second, in case of thread breakage - with the contact of the electric circuit of the machine. According to the invention, the end part of the lever interacting with the thread is located outside the outlet thread guide, it is pressed by the action of the thread tension to the outlet thread guide and partially overlaps the hole for the thread. As a result the value of the thread tension is reduced when placing into the unit, while knitting, the probability of breakage is decreased, reliability and stability of operation are increased.

EFFECT: these conditions enable to process on knitting machine threads and yarns with a lower breaking strength, including of low linear density.
