Abstract:
Apparatus for securing a plurality of cylindrical winding cores on a winding drive shaft during winding of elongated elements at differential winding rates on corresponding cores comprising:a hollow cylindrical mounting ring member defining a rotation axis and for releasably mounting a first core thereon and adapted to be rotationally slidably secured on a received drive shaft at a mounting member drive shaft interface surface, the mounting member having a plurality of bores extending radially relative to the axis;a button radially movable in each said bores;spring means for radially outwardly displacing the button in each said bores for gripping the first core mounted thereon; anda pliable distortable gripping element at said interface surface and responsive to applied radial forces created by a pressurized fluid applied directly to the gripping element to cause the gripping element to distort and to frictionally couple the mounting member to the drive shaft such that the mounting member is rotatably driven by the drive shaft at a speed and torque corresponding to the magnitude of the friction value.
