Abstract
A yarn is traversed by a drum provided with a guide groove having a plurality of the above-mentioned traversing grooves so that the returning positions at the opposite ends of the package are varied alternately in the direction of the axis of the drum, and the outer returning positions and the inner returning positions are made to creep differently. The creeping is achieved by controlling the traverse guide which travels along the guide groove with a cam.
