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.
Cette invention concerne des méthodes et un appareil de mise en rouleau et de cerclage d'une file chevauchante d'articles imprimés multifeuilles pliés en deux. Les articles imprimés chevauchants qui forment la file sont légèrement en oblique par rapport à l'axe longitudinal de transporteur sur lequel ils se trouvent. Les coins faisant ainsi saillie sur le côté de la file suivent des lignes rectilignes imaginaires parallèles audit axe longitudinal. Les articles imprimés sont par ailleurs légèrement décalés les unes par rapport aux autres dans le sens perpendiculaire audit axe longitudinal. Par conséquent, les côtés latéraux des articles mis en rouleau ne sont pas alignés et l'on évite ainsi la surépaisseur du rouleau d'un côté.
