Abstract
In the production of yarn in an open-end spinning turbine having an elastically mounted rotor bearing, a break in the yarn or an operating state which influences yarn quality is detected by means of a sensor which produces a signal representative of radial deflections of the bearing and an evaluation circuit which responds to the absence of and/or a change in the signal component produced by the sensor as a result of radial deflections created by the fiber material present on the rotor.
