ABSTRACT:
A winding shaft for a sheet rewinder comprises a hollow shaft provided in its peripheral wall with through-holes, a plurality of drum rings rotatably fitted around the hollow shaft, plungers inserted one in each through-hole, support rings provided at the opposite ends of the drum rings, and urging means disposed in the hollow shaft and adapted for outwardly urging the plungers. The hollow shaft is brought into engagement with the drum rings by means of the plungers being outwardly projected by the urging force of the urging means, consequently to permit the torque of the hollow shaft to be transmitted to the drum rings.
