ABSTRACT:
A workpiece to be balanced, which during a measuring run is driven or rotating in the coupling-free mode and is provided with a mark for contact-free pick-off to generate a reference signal, is to be positioned subsequently, that the unbalance is at a predetermined location below a marking or correcting device. To this end pulse sequences synchronous with the supporting rollers carrying the workpiece are generated. The pulses are counted in a counter between the reference signal and an unbalance position signal derived from the unbalance signal. For the positioning the counter is counted down to zero by these pulses starting from the reference pulse. When the counter passes through zero the unbalance is in the plane of the pick-off device for detecting the mark.
