Abstract

LA INVENCION SE REFIERE A UN PROCESO PARA LA PRODUCCION DE UNA PELICULA PLASTICA A PARTIR DE UN TERMOPLASTICO Y PARA ENROLLAR ESTA PELICULA PLASTICA EN UN CARRETE. LA PELICULA PLASTICA TIENE DEFECTOS DE ESPESOR SISTEMATICOS CON ESPESOR MAS DEFECTOS Y ESPESOR MENOS DEFECTOS. PARA ASEGURARSE QUE EL CARRETE SE ENCUENTRA PRACTICAMENTE LIBRE DE DEFECTOS DE ESPESOR ADICIONALES INTRODUCIDOS DURANTE LA OPERACION DE ENROLLADO, EL PERFIL DE DEFECTO DE ESPESOR DE LA PELICULA PLASTICA SE MIDE JUNTO CON SU ESPESOR SISTEMATICO MAS DEFECTOS Y/O ESPESOR MENOS DEFECTOS ANTES DE ENROLLAR LA PELICULA PLASTICA EN EL CARRETE. UNA SERIE DE CAPAS N DE LA PELICULA PLASTICA CON EL ESPESOR SISTEMATICO MAS DEFECTOS Y/O ESPESOR MENOS DEFECTOS SE ENROLLA EN LA BOBINA. ESTO SE REPITE PERIODICAMENTE, ENROLLANDOSE ALTERNATIVAMENTE N CAPAS DE LA PELICULA PLASTICA CON UN PERFIL DE DEFECTO DE ESPESOR CON APROXIMADAMENTE N CAPAS QUE TIENEN EL PERFIL DE DEFECTO DE ESPESOR INVERSO HASTA QUE SE CONSIGUE UN CARRETE SUFICIENTEMENTE CILINDRICO.
