Abstract

A winding spindle includes a plurality of support and drive rings mounted for free rotation thereon. The drive rings carry and drive winding cores, which have been slipped over the drive rings. The drive rings are able to be non-positively coupled, by their lateral annular flanks, with thrust washers. The thrust washers are connected, in a torque transmitting manner, and slidingly, with the winding spindle, and are acted upon by a thrust. In order to couple the support and drive rings to the winding spindle with an essentially constant torque along the length of the winding spindle, endless hose sections are associated with each thrust washer. The endless hose sections act to press the thrust washers directly against respective flanks of the support and drive rings with uniform force.
