Abstract

L'INVENTION SE RAPPORTE A UN ROULEAU D'ENTRAINEMENT SERVANT A FAIRE PASSER DES FEUILLES DANS LE POSTE DE FIXAGE PAR LA CHALEUR D'UN COPIEUR ELECTROSTATIQUE. SUIVANT L'INVENTION, LA SURFACE DU ROULEAU QUI ENTRE EN CONTACT AVEC LA FEUILLE A TRANSPORTER EST CONSTITUEE PAR UN GRAND NOMBRE DE PETITS ELEMENTS DE SURFACE METALLIQUES DONT LA SUPERFICIE TOTALE EST NETTEMENT SUPERIEURE A LA SURFACE PERIPHERIQUE DU ROULEAU. LES ELEMENTS DE SURFACE METALLIQUES PEUVENT ETRE CONSTITUES PAR EXEMPLE PAR LES SOMMETS DE DENTS FACONNEES DANS LA SURFACE PAR FRAISAGE OU MOLETAGE OU ENCORE PAR DES POINTES DE SOIES METALLIQUES FORMANT UNE BROSSE. L'INVENTION S'APPLIQUE AUX COPIEURS ELECTROSTATIQUES.THE INVENTION RELATES TO A DRIVE ROLLER FOR PASSING SHEETS THROUGH THE FIXING STATION BY THE HEAT OF AN ELECTROSTATIC COPIER. FOLLOWING THE INVENTION, THE SURFACE OF THE ROLL WHICH COMES IN CONTACT WITH THE SHEET TO BE TRANSPORTED IS CONSTITUTED BY A LARGE NUMBER OF SMALL METAL SURFACE ELEMENTS, THE TOTAL AREA OF WHICH IS CLEARLY GREATER THAN THE PERIPHERAL SURFACE OF THE ROLLER. THE METAL SURFACE ELEMENTS MAY BE CONSTITUTED FOR EXAMPLE BY THE TOPS OF TEETH SHAPED INTO THE SURFACE BY MILLING OR KNURLING OR AGAIN BY METAL BRISTLE POINTS FORMING A BRUSH. THE INVENTION APPLIES TO ELECTROSTATIC COPYERS.
