A friction winding shaft has a shaft body (12) and a plurality of friction rings (14), which can be driven in slaved fashion by the shaft body. By means of the friction rings (14), bushes (24) for winding operations can be driven in slaved fashion, and between the shaft body (2) and the friction elements (14), radially movable friction elements (28) are provided, which can be pressed by means of positioning elements (30) against inner circumferential surfaces (32) of the friction rings (14). In order to achieve the least possible fluctuations in the frictional moment between the shaft body and the friction ring, it is proposed that between the shaft body (12) and the friction rings (14), an air gap (34) is provided, and on the outer face of the shaft body (12), at least two slide elements (36) are provided, which rest on inner surfaces (32) of the friction rings (14).
A friction winding shaft, having a shaft body and a plurality of friction rings, which are drivable in slaved fashion in friction-locking fashion by the shaft body, and by means of the friction rings, bushes for winding operations can be driven in slaved fashion, and between the shaft body and the friction rings, radially movable friction elements are provided, which can be pressed by means of positioning elements (30) against inner circumferential surfaces of the friction rings, wherein between the shaft body and the friction rings, an air gap is provided, and on the outer face of the shaft body, at least two slide elements are provided, which rest on inner surfaces of the friction rings.
