ABSTRACT:
The present invention involves methods and apparatus for winding imbricated formations of multi-sheeted, twice-folded printing products into a roll together with a winding band wherein the individual multi-sheeted, twice-folded printing products are skewed in relation to the conveying direction of the imbricated formation by a small angle. The laterally protruding corners of the printing products lie on imaginary straight lines which run parallel to the conveying direction. The lateral fold edges of the printing products are mutually offset by a certain amount in a direction running transversely to the conveying direction. The lateral fold edges therefore do not end up one on top of the other during winding, as a result of which a thickening on one side of the roll is avoided.
