Abstract

L'invention concerne un dispositif de pliage comportant au moins un cône de pliage, monté de manière à pouvoir être déplacé dans une première direction et/ou dans le sens opposé à celle-ci, et au moins une paire de cylindres de pliage montés au-dessous du ou des cônes de pliage, et au moins un premier dispositif de coupe transversal. La ou les paires de cylindres de pliage sont montées de manière à pouvoir être déplacées dans la première direction et/ou dans le sens opposé à celle-ci, entre au moins une première position et une deuxième position. La ou les paires de cylindres de pliage sont situées, dans la première position, au moins par rapport à la première direction, plus près d'une première admission de bande du premier dispositif de coupe transversal que d'une deuxième admission de bande d'un deuxième dispositif de coupe transversal ; et la ou les paires de cylindres de pliage sont situées, dans la deuxième position, au moins par rapport à la première direction, plus près de la deuxième admission de bande du deuxième dispositif de coupe transversal que de la première admission de bande du premier dispositif de coupe transversal. L'invention concerne également une machine à imprimer.
