Abstract

L'invention concerne des installations d'extrusion de films utilisant des distributeurs hélicoïdaux permettant de produire une matière fondue aussi homogène que possible lors d'une utilisation. Les distributeurs hélicoïdaux sont présents la plupart du temps sous la forme de distributeurs hélicoïdaux axiaux cylindriques ou coniques ou sous la forme de distributeurs hélicoïdaux radiaux. Les canaux hélicoïdaux s'étendent sur un support hélicoïdal de manière à former de multiples spirales. Selon l'invention, une spirale est disposée d'une manière déterminée sur un corps antagoniste faisant face au support hélicoïdal, et ce pour réaliser une forme de section transversale ronde, la spirale s'étendant en continu dans une partie de départ, mais se terminant dans une partie de débordement. Par ailleurs, l'invention vise à fournir une section transversale ronde déjà sur le support hélicoïdal.
