Abstract

Perfeccionamientos en dispositivos para la extrusión de extruídos plásticos planos, o bien bandas y hojas de masa plástica, por medio de una cabeza inyectora que presenta una boquilla, caracterizados porque la boquilla muestra una zona de entrada que desemboca en un canal de fundido recto con ranura de salida con una sección recta de paso que se estrecha de forma convexa entre dos superficies enfrentadas y porque el canal de fundido está subdividido en su ranura de salida mediante al menos un pasador central que sirve como divisor de extruído que discurre transversalmente a la longitud de la ranura.
