Abstract

DISPOSITIVO PARA LA FABRICACION DE UNA PELICULA TUBULAR DE ESTRUCUTRA LAGUNAR, QUE COMPRENDE DOS CORONAS CIRCULARES EXCENTRICAS QUE FORMAN UNA RANURA PARA LA EXTRUSION DE LA PELICULA. UNA DE LAS DOS CORONAS ES MOVIL ALREDEDOR DE LA OTRA, ESTANDO AMBAS EN CONTACTO PERMANENTE POR UN PUNTO QUE SE DESPLAZA SOBRE EL CONTORNO DE LA CORONA FIJA. UNA DE LAS CORONAS ESTA PROVISTA DE DENTADOS PARA PRODUCIR PERFORACIONES EN LA PELICULA, ESTANDO LAS CORONAS DISPUESTAS DE MODO QUE LA ACCION DE PERFORACION SE REALICE CORRIENTE ABAJO DE LA RANURA DE EXTRUSION SOBRE LA PELICULA QUE NO ESTA APOYADA SOBRE LA PARED DE LA CORONA FIJA.
