Abstract

L'invention concerne une structure de pliage (04) d'une presse offset rotative vers laquelle sont acheminées simultanément au moins une première bande (02) présentant une pluralité k de pages imprimées d'un format de page imprimée placées les unes à côté des autres, et au moins une deuxième bande (02) présentant une pluralité k de pages imprimées d'un deuxième format de page imprimée placées les unes à côté des autres dans au moins un type de production de la presse. La structure de pliage présente au moins un plan de cônes (19) comprenant au moins deux cônes plieurs (13) disposés l'un à côté de l'autre, au moins une première bande ou plusieurs bandes partielles (02) obtenues par coupe longitudinale de ladite première bande pouvant être acheminées vers le plan de cônes. Un dispositif de coupe longitudinale (12) par lequel la deuxième bande peut être coupée en une pluralité de bandes partielles (02) de la largeur d'une page est associé à la structure de pliage (04) dans la région de son entrée ou sur un trajet vers l'amont de la deuxième bande. Il est prévu dans l'alignement vertical au-dessus de ce plan de cônes (19) une table de sortie (21) pourvue d'un nombre i d'au moins quatre barres de déviation (22) décalées les unes par rapport aux autres dans la direction transversale par lesquelles toutes les bandes partielles de la largeur d'une page obtenues par coupe longitudinale à partir de la deuxième bande peuvent être simultanément amenées déviées de 90° vers un côté extérieur de la structure de pliage, la deuxième bande (02) en tant que bande initiale avant la coupe longitudinale portant de manière juxtaposée un nombre k1 d'au moins trois images imprimées de pages imprimées d'un format de page imprimée, et au moins trois bandes partielles de la largeur d'une page étant acheminées sur la table de sortie (21) vers un côté ou les deux côtés de la structure de pliage (04). Dans la structure de pliage, il est prévu des moyens de direction et/ou de déviation (23, 31, 32, 38, 39, 43, 59, 61, 72) par l'intermédiaire desquels la pluralité de bandes partielles déchargées latéralement, obtenue à partir de la deuxième bande, peut être regroupée dans une ou plusieurs lignes de magasin multicouches et/ou dans plusieurs lignes de magasin au moins monocouches (29,36,41,44) en contournant le cône plieur (13) ayant au moins un niveau de cône (16) formé d'au moins une première bande ou bande partielle par l'intermédiaire d'un cône plieur pour former une ligne globale (37) avant que cette ligne globale (37) soit coupée transversalement dans un appareil de pliage (06) et puisse être transformée en un produit (P) à présenter.
