Abstract

La présente invention concerne une tête d'extrusion (1) destinée à être placée au niveau d'une extrémité d'un fourreau équipant une extrudeuse, la tête d'extrusion (1) présentant : • une filière (7) configurée pour mettre en forme un matériau élastomère de manière à obtenir un profilé, et • au moins un noyau (11) disposé à l'intérieur de la filière (7) présentant une forme configurée pour former un canal longitudinal dans le profilé, ce canal longitudinal présentant une paroi interne de section complémentaire à la forme du noyau (11), caractérisée en ce que le noyau (11) de la tête d'extrusion (1) présente au moins un canal d'amenée d'air (15) configuré pour pouvoir amener de l'air dans le sens d'écoulement du matériau élastomère dans le canal longitudinal de manière à maintenir la forme générale de la section de la paroi interne du canal longitudinal.
