Abstract
A ring spinning machine with various driving systems 10, 12 for driving spindles, driving arrangements, ring rails and the like is regulated in the case of power failure down to a zero revolution range while maintaining preselected revolution relationships. The driving system which is allocated to the load with the greatest effective inertia serves, at first, for the supply of the other driving system in a generator service. Only in a lower revolution range are the driving systems backed via a battery of relatively low capacity.
