Abstract
A winding core for winding printed products. The core includes two coil parts, each of which includes at least one coiled profile and a step on each of an inner face and an outer face thereof. The step is formed by a corresponding one of two ends of the at least one coiled profile, each coiled profile further including coil windings having cooperating first joining components disposed on axial sides thereof for joining the windings to one another, each coiled profile having a freely selectable axial extension thereby allowing a free selection of an axial extension of the hollow cylinder. Two end rings of the core include second joining components thereon cooperating with the first joining components for axially joining the two end rings to the coil parts, each inner face of each end ring facing a corresponding coil part including a step thereon juxtaposed against and having an axial extension substantially equal to an axial extension of a corresponding step of the corresponding coil part. A middle ring of the core includes third joining components thereon cooperating with the first joining components for axially joining the middle ring to the coil parts, each of two faces of the middle ring facing a corresponding coil part and having a step thereon juxtaposed against and having an axial extension substantially equal to an axial extension of a corresponding step of the corresponding coil part.
