Abstract

Cette unité de revêtement permettant de transférer des couches qui forment une image ou qui assurent un recouvrement à partir d'un film de transfert sur une matière à imprimer doit être utilisable de manière flexible afin de produire des matières à imprimer complexes en film. A cet effet, au moins un module FA d'application de film est installé dans une rotative d'impression de feuilles de telle sorte qu'on crée une combinaison variable en association avec des groupes d'impression, des groupes de peinture. En particulier, la feuille revêtue en film doit pouvoir être séchée par son côté arrière.
