Abstract
When preliminarily storing yarn on a drum-shaped storage body of a feeding device in which the yarn is placed on the storage body by an electrical winding drive with relative rotational movements between a winding element and the storage body, with running periods and resting periods, during each resting period a holding torque is generated in the winding direction. The holding torque is generated electrically in the winding drive mechanism. A backturn detent device serves to block a reverse rotation of the winding element during resting periods. The backturn detent device is actuated by a holding current during each resting period.
