Abstract

L'invention concerne un système destiné au sectionnement en longueur d'un tube (12), notamment fabriqué en couches de papier ou en carton, comprenant un dispositif d'appui (17, 18) disposé dans un plan de sectionnement (T) et destiné à être disposé à l'intérieur du tube (12) et un dispositif de coupe (19, 20) disposé dans le plan de sectionnement (T) et destiné à être disposé à l'extérieur du tube. Le dispositif d'appui (17, 18) et le dispositif de coupe (19, 20) sont disposés en vis-à-vis l'un de l'autre dans le plan de sectionnement (T) et forment un premier arrangement de sectionnement (21) servant au sectionnement d'une portion de paroi de tube (13, 14). Le dispositif de coupe (19, 20) possède un couteau circulaire (24) disposé sur un arbre de coupe (23) entraîné et le dispositif d'appui (17, 18) un galet d'appui (26) disposé sur un axe d'appui (25). L'arbre de coupe (23) et l'axe d'appui (25) sont disposés à un entraxe a l'un de l'autre de telle sorte qu'un espace de coupe est défini dans le plan de sectionnement (T) entre une arête de coupe du couteau circulaire (24) et une surface d'appui du galet d'appui (26).
