Abstract

Perfeccionamientos en los útiles de extrusión para la fabricación de tubos de plásticos, con una boquilla de extrusión con carcasa exterior, y núcleo, cuya rendija anular de salida es regulable en su anchura mediante desplazamiento axial del núcleo de la boquilla en la abertura de la carcasa que se reduce en su anchura cónicamente, caracterizados porque la camisa del núcleo de la boquilla que va montada desplazable en la pieza central y entra en contacto con el material a extrusionar está constituida hasta su extremo libre de forma axialmente paralela, en particular cilíndrica.
