Abstract

L'invention concerne un procédé de préparation de l'axe (10a) d'une machine à refendre destinée à refendre une bande dans le sens de la longueur. Le procédé consiste à utiliser une cale (38) annulaire sur l'axe pour compenser un écart (40) entre la face extérieure de travail d'un anneau d'éjection (16) entourant l'axe et un bord (20) de refendage d'un couteau (12) sur l'axe. L'anneau d'éjection possède un diamètre intérieur proportionné de manière à permettre une rotation sensiblement libre de l'anneau d'éjection autour de l'arbre en l'absence de la cale. En utilisant la cale ou en la retirant de l'axe, on peut utiliser l'anneau d'éjection pour refendre des bandes de différentes épaisseurs. L'invention concerne également une machine à refendre comprenant un axe qui comporte une cale entourée d'un anneau d'éjection, tel que décrit ci-dessus.
