Abstract
Raccord tournant destiné à l'alimentation d'une filière d'extrusion avec au moins deux courants de matière thermoplastique. Il comprend un conduit cylindrique présentant plusieurs canaux dont les trous d'entrée sont alignés avec des trous de décharge réalisés dans l'embase fixe d'un distributeur. Ces canaux sont destinés à diriger des courants de matière thermoplastique du distributeur vers une filière d'extrusion. Domaine d'application : fabrication de tubes multicouches par extrusion.
