GLAZING AND METHOD OF MANUFACTURING

Abstract

Abstract Translated from French L'INVENTION CONCERNE UN ASSEMBLAGE PREFORME D'UNE FEUILLE TRANSPARENTE ET D'UN JOINT COLLE A SA PERIPHERIE, AINSI QUE LE PROCEDE DE FABRICATION DE CET ASSEMBLAGE. LE JOINT 22 EST FORME D'UNE MATIERE A BASE DE POLYURETHANE THERMODURCISSABLE, MOULEE SUR LE POURTOUR DE LA FEUILLE 20 QUI EST AVANTAGEUSEMENT EN VERRE. LE MOULAGE S'EFFECTUE PAR INJECTION DANS UNE CAVITE DE MOULE ET LA PRESSION, RESULTANT DE LA POLYMERISATION, FAIT PORTER LA MATIERE DU JOINT EN CONTACT INTIME AVEC LA CAVITE DU MOULE ET AVEC LA FEUILLE. DOMAINE D'APPLICATION: FABRICATION DE PARE-BRISE, LUNETTES ARRIERE ET AUTRES VITRAGES POUR VEHICULES ET AUTRES. THE INVENTION CONCERNS A PREFORMED ASSEMBLY OF A TRANSPARENT SHEET AND A JOINT GLUED TO ITS PERIPHERY, AS WELL AS THE PROCESS FOR MANUFACTURING THIS ASSEMBLY. THE SEAL 22 IS IN THE FORM OF A MATERIAL BASED ON THERMOSETTING POLYURETHANE, MOLDED ON THE PERIOD OF THE SHEET 20, WHICH IS ADVANTAGEOUSLY IN GLASS. THE MOLDING IS CARRIED OUT BY INJECTION IN A MOLD CAVITY AND THE PRESSURE, RESULTING FROM THE POLYMERIZATION, MAKES THE SEAL MATERIAL IN INTIMATE CONTACT WITH THE CAVITY OF THE MOLD AND WITH THE SHEET. FIELD OF APPLICATION: MANUFACTURE OF WINDSHIELDS, REAR GLASSES AND OTHER WINDOWS FOR VEHICLES AND OTHERS.
