Abstract

Le système de vannes selon l'invention comporte une ou plusieurs vannes ayant des tiges de vannes fixes 24, chacune établissant un étranglement annulaire 25 d'une longueur fixe dans le distributeur 21 et une ou plusieurs vannes à tiges réglables 28, chacune établissant un étranglement annulaire 29 de longueur variable dans le distributeur. Un tel système convient en particulier pour l'extrusion simultanée de plusieurs films devant avoir la même épaisseur.
