Abstract

A draw frame for a spinning machine is provided with roving blocking mechanism associated with its inlet rollers actuable on rupture of the remittant thread to arrest movement of the roving and is further provided with a sensor for detecting the continuity of the roving being fed from a source of supply and a roving clamp situated between the sensor and the blocking mechanism. The blocking mechanism and the roving clamp are arranged to be simultaneously operated in response to a signal from the sensor or in response to rupture of the thread.
