Abstract
Abstract A delivery device for running threads with a winding body, to which the thread for forming a winding storage runs tangentially in the rearward range and from which the thread is pulled in axial direction over head, which comprises a winding body including a polygon of a plurality of individual rods. An abutment face is controlled trailingly to a thread feeding station and projects beyond a feeding plane, in order to advance the winding storage towards the head end of the winding body.
