Abstract
The arrangement includes a drive motor for driving the winding member of a yarn storage and dispensing unit. The output torque of the drive motor is substantially independent of the momentary operational speed. The drive motor either is a synchronous hysteresis motor comprising means for suppressing eddy currents, or is a DC motor the motor current of which is maintained at a constant value corresponding to the desired driving torque.
