Abstract

L'invention concerne un extracteur (1) pour un système d'extrusion (4). Le système d'extrusion comprenant un arbre cannelé (40) et des éléments de vis (41) montés successivement sur l'arbre cannelé pour former une vis d'extrusion (42). L'extracteur (1) comprend un premier dispositif de maintien (3) configuré pour immobiliser l'arbre cannelé (40), un second dispositif de maintien (5) configuré pour agripper un des éléments de vis (41) et un dispositif d'actionnement (6) configuré pour déplacer le second dispositif de maintien (5) selon un axe de translation (X1) parallèle à un axe longitudinal (X3) de l'arbre cannelé (40) en sorte d'écarter ledit élément de vis (41) agrippé du reste de la vis d'extrusion (42). L'extracteur permet de dégripper les éléments de vis de l'arbre cannelé.
