Abstract

SE UTILIZA UN APARATO DE PRODUCCION EN EL QUE SE COLOCA UNA CORREA METALICA SIN FIN QUE TIENE UNA SUPERFICIE DE ESPEJO A ENROLLAR SOBRE O ENTRE UN PRIMER RODILLO DE ENFRIAMIENTO, CUBIERTO CON UN MIEMBRO ELASTICO, Y UN SEGUNDO RODILLO DE ENFRIAMIENTO, Y UN TERCER RODILLO DE ENFRIAMIENTO, QUE TIENE UNA SUPERFICIE DE ESPEJO SOBRE SU SUPERFICIE Y QUE ENTRA EN CONTACTO CON EL PRIMER RODILLO DE REFRIGERACION A TRAVES DE UNA HOJA DE RESINA TERMOPLASTICA Y LA CORREA SIN FIN, DISPUESTO PARA MANTENER LA HOJA DE RESINA TERMOPLASTICA FUNDIDA PRESIONADA CON LA CORREA SIN FIN. MIENTRAS LA TEMPERATURA DEL TERCER RODILLO DE ENFRIAMIENTO Y DE LA CORREA SIN FIN EN CONTACTO DIRECTO CON LA HOJA DE RESINA TERMOPLASTICA FUNDIDA SE MANTIENE A MENOS DE 50 (GRADOS) C Y A MAS DE CERO, LA HOJA DE RESINA TERMOPLASTICA FUNDIDA ES GUIADA HASTA DENTRO DEL AREA QUE HAY ENTRE EL PRIMER Y TERCER RODILLOS DE ENFRIAMIENTO DE MODO QUE ENTRE EN CONTACTO CON LA CORREA SIN FIN, ENTRANDO EN CONTACTO CON EL PRIMER RODILLO DE ENFRIAMIENTO, Y EL TERCER RODILLO DE ENFRIAMIENTO AL MISMO TIEMPO MAS O MENOS, Y LA HOJA DE RESINA TERMOPLASTICA FUNDIDA ES ENROLLADA POR CONTACTO SOBRE LA SUPERFICIE Y ENFRIADA POR EL PRIMER Y TERCER RODILLOS DE ENFRIAMIENTO DURANTE LA DEFORMACION ELASTICA DEL MIEMBRO ELASTICO, PROVOCADA POR UNA FUERZA DE PRESION ENTRE EL PRIMER Y TERCER RODILLOS DE ENFRIAMIENTO, Y POSTERIORMENTE, LA HOJA DE RESINA TERMOPLASTICA FUNDIDA SE ENFRIA A BASE DE ENROLLAR POR CONTACTO LA SUPERFICIE EN EL TERCER RODILLO DE ENFRIAMIENTO CON LA CORREA SIN FIN.
