Patent

CA 2644925

A screw element, in particular a kneading element (1), to be used with a plasticating unit, having a screw shank with at least two kneading units, wherein the kneading units can be arranged on a common axis, for example the screw shank, and wherein the kneading units have a geometry, is designed with a view to particularly good plastication and reduced mechanical stress in such a way that the geometry of at least two successively arranged kneading units differs.

L'invention concerne un élément hélicoïdal, en particulier un élément de pétrin (1) destiné à être utilisé avec une unité de plastification dotée d'un arbre de vis et d'au moins deux unités de pétrissage. Les unités de pétrissage peuvent être disposées sur un arbre commun, par exemple l'arbre de vis, et les unités de pétrissage ont une géométrie qui leur permet de réaliser une plastification particulièrement bonne sous une charge mécanique réduite, au moins deux unités de pétrissage disposées l'une après l'autre ayant des géométries différentes.
