Abstract

EL PROCESO DE FABRICACION DE EMPAQUETADURAS DE ESTANQUEIDAD SEGUN LA INVENCION COMPRENDE UNA FASE DE PREPARACION DE UN ELASTOMERO EN EL QUE SE AÑADEN FIBRAS (14, 32) POR EJEMPLO DE CELULOSA O DE FIBRAS ARAMIDAS Y UNA FASE DE FORMACION QUE UTILIZA UN PROCEDIMIENTO DE CIRCULACION DEL ELASTOMERO QUE PERMITE OBTENER UNA ORIENTACION PREFERENCIAL DE LAS FIBRAS (14, 32) EN EL INTERIOR DE LA JUNTA REALIZADA. ESTE PROCESO PERMITE OBTENER UNA JUNTA EN LA QUE LAS FIBRAS PUEDEN ORIENTARSE HACIA LA SUPERFICIE DE CONTACTO DE ESTA JUNTA QUE ASEGURA UNA ESTANQUEIDAD DINAMICA.
