Abstract

A yarn is wrapped around a portion of a rotary element which is rotating in the direction of feed. The periphery of the rotary element includes a plurality of openings through which an air stream is induced, the air stream tending to urge the yarn out of engagement with the rotary element, whereby the tension and frictional effect on the yarn around the rotary element may be varied in response to downstream conditions in order to obtain constant tension in the yarn being delivered to downstream machines regardless of the tension on the yarn as it is received at the rotary element from a supply source.
