Abstract

DISPOSITIF DE FUSION A ROULEAUX ET SYSTEME DE REPARTITION D'AGENT DE DEGAGEMENT POUR CELUI-CI. L'INVENTION CONCERNE UN DISPOSITIF DE FUSION A ROULEAUX CHAUFFE ET DE PRESSION QUI PERMET LA FIXATION D'IMAGES AUX SUBSTRATS DE COPIE, L'AGENT DE FIXATION (TONER) COMPREND UNE RESINE THERMOPLASTIQUE. LE DISPOSITIF COMPREND UN ROULEAU DE FUSION CHAUFFE INTERIEUREMENT QUI COOPERE AVEC UN ROULEAU DE PRESSION POUR FORMER UN ETRANGLEMENT DANS LEQUEL PASSENT LES SUBSTRATS DE COPIE AVEC LES IMAGES EN CONTACT AVEC LE ROULEAU CHAUFFE. LE ROULEAU CHAUFFE COMPORTE UNE COUCHE EXTERIEURE QUI PEUT ETRE EN CAOUTCHOUC AU SILICONE EN VITON OU COMPORTE UN REVETEMENT METALLIQUE RECOUVERT D'UN MATERIAU A FAIBLE ENERGIE DE SURFACE TEL QUE LE TEFLON AUQUEL EST APPLIQUE UN FLUIDE POLYMERE DE DEGAGEMENT A FAIBLE VISCOSITE. CELUI-CI EST APPLIQUE DIRECTEMENT OU INDIRECTEMENT AU ROULEAU DE FUSION. LORSQUE L'APPLICATION SE FAIT DIRECTEMENT, UN JOINT D'AIR DOIT ETRE FORME SUR LA SURFACE DU ROULEAU DE FUSION DE FACON A ASSURER UN BON CONTACT DU MATERIAU AVEC LE ROULEAU. EN VARIANTE, EN CAS D'APPLICATION INDIRECTE, PAR EXEMPLE PAR UN ROULEAU DE REPARTITION, LE JOINT D'AIR EST EN CONTACT AVEC CE DERNIER ROULEAU. APPLICATION AUX DISPOSITIFS DE REPRODUCTION PAR XEROGRAPHIE.
