Abstract

LE DISPOSITIF DE FUSION DE L'INVENTION PERMET LA FIXATION D'IMAGES OBTENUES PAR AGENT DE MARQUAGE A DES SUBSTRATS DE COPIE, PAR EXEMPLE A DU PAPIER, ET COMPREND UNE PAIRE DE ROULEAUX 12, 26, DONT L'UN 12 EST CHAUFFE ET COMPORTE UNE COUCHE EXTERIEURE 19 DEFORMABLE SUR LAQUELLE PASSE LE PAPIER. LA COUCHE EXTERIEURE 19 EST DEFORMEE PAR UN ROULEAU D'APPUI PLUS DUR 26 ET UN ETRANGLEMENT 20 EST CREE. UN DISPOSITIF PNEUMATIQUE 35, PLACE PRES DE LA SORTIE DE L'ETRANGLEMENT, PERMET D'ASSURER QUE LE BORD AVANT DU PAPIER QUI SE DETACHE DE LUI-MEME DU ROULEAU CHAUFFE RESTE HORS DE CONTACT DE CE ROULEAU APRES DETACHEMENT.THE FUSION DEVICE OF THE INVENTION ALLOWS THE ATTACHMENT OF IMAGES OBTAINED BY THE MARKER TO COPY SUBSTRATES, FOR EXAMPLE PAPER, AND INCLUDES A PAIR OF ROLLS 12, 26, ONE OF WHICH IS HEATED AND CONTAINED A DEFORMABLE OUTER LAYER 19 OVER WHICH THE PAPER PASSES. THE OUTER LAYER 19 IS DEFORMED BY A HARDER BACKUP ROLLER 26 AND A THROTTLE 20 IS CREATED. A PNEUMATIC DEVICE 35, PLACED NEAR THE EXIT OF THE THROTTLE, ENSURES THAT THE FRONT EDGE OF THE PAPER WHICH IS DETACHED FROM ITSELF FROM THE HEATED ROLLER REMAINS OUT OF CONTACT WITH THIS ROLL AFTER DETACHMENT.
