DISPOSITIVO PER CONTROLLARE CHE IN UNA MACCHINA TESSILE UN FILO NON FORMI SPIRE INDESIDERATE

摘要

The device has a limiting element (6) arranged in the proximity of a rotary roller (3) such that a thread winding produces a yarn accumulation between the roller and the limiting element and a brake torque exerts on the roller. The brake torque is detectable for detection of a thread winding by a control unit. The limiting element is designed as a tangential plate arranged to the periphery of the roller. The limiting element is designed as a rod that is arranged parallel to the axis of the roller at its periphery.
