Abstract

L'invention concerne la fabrication d'objets tubulaires façonnes. Un objet tubulaire extrudé est refroidi par passage à travers un bain de liquide de refroidissement de telle sorte que la surface externe du produit vienne en contact, dans l'ordre, avec des courants de liquide de refroidissement dans une zone calme, une zone étranglée et une zone à écoulement hélicoïdal. Cet objet tubulaire extrudé est utilisé pour fabriquer des pellicules orientées.
