ABSTRACT:
The present invention provides a method and apparatus which enables thread to be wound onto the motor driven storage drum of a thread storage and feeding device for a thread processing machine strictly continuously and uniformly with the aim of ensuring that the thread as wound off the thread supply bobbin is wound onto the storage drum in such a way that variations in the tension of the thread as pulled off the storage drum are eliminated. This is achieved by controlling the number of revolutions of the motor in response to a control signal which is derived from the thread intermediate supply on the drum and the actual thread consumption, i.e., the average speed of the thread leaving the drum.
