ABSTRACT:
The electronic scanner serves to monitor a multitude of thread running locations in a textile machine in which a measuring head for detecting a thread rupture or breakage, a bistable controller and switching means are arranged at each thread running location. A clock pulse generator acts upon the clock pulse inputs of the bistable controllers which are series connected and which interrogate or scan the measuring heads via the switching means in a cyclical sequence. The signals obtained from the measuring heads during interrogation or scanning are delivered to a counting circuit via a signal line and a clock-pulse controlled gate. The counting circuit indicates the thread running location associated with a thread rupture.
