A roving frame has a flyer region into which the suspension carriage trains are moved past a device for monitoring the presence or absence of cores or bobbins on the hangers. An error signal is transmitted in the case of an error and correction is effected when the suspension carriage train is in the flyer region. The suspension carriage train is then moved back past the sensors and either on this backward movement or the next forward movement, the functional correctness or poor mounting is again measured. Correction is effected in each case in the flyer region where the hangers are more readily accessible.

Monitoring of core mounting for a roving frame

A method of and an apparatus for controlling the drive of a machine element of a spinning or twisting machine for exact positioning of the machine element at setpoint positions within a certain tolerance limit using motors which are not speed variable and are controlled by an on-off switch. The overshooting of the setpoint position can be detected and the measure of overshoot used as correction values for subsequent approaches to the setpoint position or to allow reverse approach to the setpoint with detection of overshoot beyond the tolerance and then a new approach with the iteration to a deviation less than the tolerance limit or a maximum number of cycles.
