Abstract

Se describe una máquina de coextrusión para la producción de un perfil complejo en el que los elementos de perfil formados respectivamente de una primera mezcla de caucho (M1) y una segunda mezcla de caucho (M2) se yuxtaponen transversalmente sin superponerse, que comprende: - un rodillo cilíndrico , - un cabezal de extrusión que comprende una cavidad de extrusión y: un bloque de extrusión corriente arriba (3) de la primera mezcla (M1) que comprende un canal de extrusión corriente arriba (31); una cuchilla de perfilado corriente arriba (32) ); un bloque de extrusión corriente abajo (4) de la segunda mezcla (M2) que comprende un canal de extrusión corriente abajo (41); una cuchilla de perfilado corriente abajo (42). El cabezal de extrusión soporta rascadores (7) que se extienden longitudinalmente entre la entrada del canal de extrusión corriente arriba (31) y la cuchilla de perfilado corriente arriba (32) dividiendo el canal de extrusión corriente arriba (31) en subcanales (310). Los rascadores tienen una pared radialmente interna que se apoya sobre la pared radialmente externa del rodillo.
