Abstract
The production of defective yarn in a friction false-twisting unit is deted and prevented. Variations of speed of rotation caused by defects in drive elements, such as worn or jammed bearings or a damaged drive belt, are detected by comparing a signal indicating the speed of rotation of at least one shaft with a reference signal. If the signal differs from the reference signal, an electrical fault signal is generated. This fault signal may control a thread cutting device which cuts the thread coming from the unit; or the fault signal may go to a central thread monitoring station where an operator may observe that a fault has occurred.
