Abstract

An open-end rotor spinning machine includes a plurality of spinning stations each including a first thread monitor monitoring a thread course and a rotor spinning device receiving a fiber supply and having a spinning element; an automatic thread joining device for joining a thread to be conducted to the rotor element, and a second thread monitor disposed on the automatic thread joining device for monitoring the thread course without placing a load on the thread when the first thread monitor is inoperative and the automatic thread joining device is operative, the automatic device delivering the second thread monitor and a thread to a location directly adjacent the spinning element, and the second thread monitor including a device for immediately interrupting the fiber supply to the rotor spinning device if the second thread monitor detects the absence of the thread.
