Abstract

L'objectif est d'améliorer l'efficacité de dégazage par la formation de multiples trous d'injection sur un cylindre et l'injection d'une aide de dégagement des matières volatiles à travers les trous d'injection. L'invention concerne une extrudeuse-malaxeuse à vis qui comprend un cylindre (2) ayant un alésage interne (2a). L'alésage interne (2a) a de multiples trous d'injection (4) formés sur celui-ci à différentes positions dans une direction périphérique. Une aide au dégagement des matières volatiles (10) est distribuée à travers les trous d'injection (4), ce par quoi l'efficacité de dégazage peut être améliorée.
