Abstract

L'invention concerne un mécanisme de transfert d'image. Selon l'invention, il comprend une bande rotative sans fin 24 avec une partie de pellicule électrophotographique; un moyen d'entraînement 88 pour entraîner la bande à travers un groupe de stations comprenant une station de charge 14 avec un moyen générateur d'effet corona 28 et 30, une station d'exposition 16 avec un moyen 32, 34 pour arrêter la pellicule, une station de virage 18 avec des moyens 44, 46, 48, 50, 51, 52 pour appliquer une quantité constante de produit de virage sur la largeur du côté avant de la pellicule, et une station de transfert 20 comprenant un moyen de transfert 64, 66, 68, 72 d'une image de la pellicule à un support de transfert L'invention s'applique notamment à l'impression en offsetAn image transfer mechanism is disclosed. According to the invention, it comprises an endless rotating belt 24 with part of electrophotographic film; drive means 88 for driving the tape through a group of stations comprising a charging station 14 with corona generating means 28 and 30, an exposure station 16 with means 32, 34 for stopping the film , a toning station 18 with means 44, 46, 48, 50, 51, 52 for applying a constant amount of toning product across the width of the front side of the film, and a transfer station 20 including transfer means 64, 66, 68, 72 of an image from the film to a transfer medium The invention applies in particular to offset printing
