A winding shaft is described, having self-tensioning individual winding elements (6) for winding mandrels mounted on it in such a way that they can be driven, which include in each case in an annular groove (14) of each individual winding element a compliant tensioning means, the outside diameter of which is greater than the inside diameter of the winding mandrels. The winding means comprises a plurality of cylindrical-annular segments (2) arranged on the circumference of the individual winding element in the annular groove, the end faces (13) of which segments are beveled and are mounted radially displaceably on the inner face of the intermediate pieces (3), there being seated between the inside of the segments and the bottom of the annular groove a spring element, comprising either a leaf spring or a plurality of helical springs with ball thrust pieces.
