Abstract

_(PROCEDIMIENTO PARA EXTRUIR EN CONTINUO A TRAVES DE UN FILTRO FINO, EN PARTICULAR PARA EL AISLADO, POR EXTRUSION DE POLIMEROS TERMOPLASTICOS, DE HILOS Y CABLES ELECTRICOS . EL PRODUCTO A EXTRUIR SE HACE PASAR POR UNA PRIMERA EXTRUSORA (1), DESPUES POR UN FILTRO INTERCAMBIABLE (3), FRANQUEA UN MEDIO DE OBTURACION (5), PENETRA EN UN DEPOSITO INTERMEDIO (7) PROVISTO DE UN MEDIO DE PUESTA EN PRESION (8, 9, 10) Y LUEGO DESEMBOCA EN LA EXTRUSORA CURSO ABAJO 4 (12) QUE LO EXPULSA HASTA EL CABEZAL DE EXTRUSION (13). EL FILTRO PUEDE CAMBIARSE SIN INTERRUMPIR NI VARIAR SENSIBLEMENTE EL CAUDAL DE PRODUCTO EXTRUIDO EN EL CABEZAL DE EXTRUSION.
