Abstract

Procédé de fabrication d'éléments hélicoïdaux en matière plastique dans lequel on extrude un boudin ou filament de matière plastique-chaude depuis une filière d'extrusion. On fait tourner la filière autour d'un axe vertical, on extrude le boudin ou filament de la filière selon une direction horizontale ou assez faiblement inclinée par rapport à l'horizontale, et ceci à une faible distance au-dessus de la surface d'une masse de fluide. L'invention permet une fabrication à grand débit.
