ABSTRACT:
To decrease the time required for spindles of a spinning machine to reach their normal operating speeds after a yarn breakage or the like, where the spindles are individually driven by respective asynchronous motors individual to the spindles, the alternating current source whose frequency defines the speed of the motor is temporarily brought to a voltage above the normal operating voltage and the voltage step-up is then terminated.
