Abstract
SE DESCRIBE UN EQUIPO CON UN INTERSTICIO ANULAR (20) EN TOBERA LABIADA DE UNA CABEZA DE EXTUSIONADOR SIENDO POSIBLE AJUSTAR LA ABERTURA DEL INTERSTICIO ANULAR ENTRE LA PIEZA LABIADA INTERIOR (3) Y LA PIEZA LABIADA EXTERIOR (4) DE ACUERDO CON EL ESPESOR DESEADO DEL MATERIAL A EXTRUSIONAR. SE EFECTUA ESTA VARIACION SIN QUE EL PROCESO DE EXTRUSIONADO DEBA SER INTERRUMPIDO Y SIN QUE EL EXTRUSIONADO DE FORMA DE MANGUERA DETRAS DE SU LUGAR DE SALIDA Y ANTES DE LA CAPA SOBRE LA ESPIGA ENFRIADORA (10) DEBA SER SEPARADO. ESTA MEJORA SE CONSIGUE DE ACUERDO CON ESTA INVENCION YA QUE LA PIEZA DE TOBERA LABIADA (4) EXTERIOR, POSEE UNA CONEXION DESMONTABLE QUE PERMITE UN DESPLAZAMIENTO HIDRAULICO DE LA PIEZA LABIADA EXTERIOR DE LA TOBERA CON RELACION A LA PIEZA LABIADA INTERIOR.
