ABSTRACT:
A winding mechanism with a friction drive roller for driving the winding package; at least one peripherally tapered, friction drive wheel inside the friction drive roller for rotatably driving same at variable speeds, the variation of which is obtained by axial shifting of the friction drive roller and its support; cam control means for attaining the axial shifting with increasing diameter of the winding; and the friction drive inside the roller being disengageable upon movement of the roller at right angles to its axis of rotation.
