The winding body (14) of the winding core (10) has on its side edges (20, 20') projections (22), projecting in the direction of the longitudinal axis (12) beyond the printing products (40) wound-up on the winding core (10), and recesses (24) partially covered by the printing products (40). During the stacking of rolls (38) one on top of the other in a tower-like manner, the projections (22) of one winding core (10) engage in the recesses (24) of the winding core (10) of the neighboring roll (38). During stacking, the wound-up printing products (40) of the rolls (38) consequently come into contact with one another. A mutual slipping of the rolls (38) during transport is thereby prevented.
