Abstract
Abstract The yarn is wound up from the spinning device at a constant tension. The apparatus includes a shiftable friction ring which varies the speed of the winding drum in response to the yarn tension as determined by a yarn feeler. The actuation of the control means to shift the friction ring can be immediate or delayed.
