ABSTRACT:
The winding body of the winding core has on its opposite ends projections, projecting in the direction of the longitudinal axis beyond the printing products wound up on the winding core, and recesses partially covered by the printing products. During the stacking of rolls one on top of the other in a tower-like manner, the projections of one winding core engage in the recesses of the winding core of the neighboring roll. During stacking, the wound up printing products of the rolls consequently come into contact with one another. Mutual slipping of the rolls during transport is thereby prevented.
