Abstract
L'invention porte sur un dispositif de fabrication d'un barreau composite à plusieurs composants, caractérisé par le fait qu'il comprend : - un boîtier de raccordement (1), comprenant des moyens de raccordement à des extrudeuses, et une pièce de guidage (9) des extrudats issus de chacune des extrudeuses, constituée d'un canal central (13) et de canaux périphériques disposés autour du canal central (13) ; et - une filière comprenant un canal central et des canaux secondaires, la filière étant fixée au boîtier de raccordement (1) à la sortie de la pièce de guidage (9), le canal central de la filière s'évasant de l'entrée de la filière à la sortie de la filière pour enserrer chacun des canaux secondaires de la filière, de telle sorte qu'en sortie de la filière la sortie du canal central de la filière entoure la sortie de chaque canal secondaire de la filière pour former un barreau composite à n composants co-extrudés.
