Abstract

Plutôt que d'effectuer une seconde passe sur la cartouche dans les mêmes rainures de rouleau 5, après l'avoir fait tourner de 90 degrés , on amène cette cartouche à un deuxième poste de travail et on la fait passer dans la rainure 5' d'un deuxième rouleau, tout en faisant passer une deuxième cartouche dans la rainure 5 du premier rouleau. On améliore ainsi la forme de la cartouche après chaque passe du fait que l'on peut jouer sur la forme des rainures.
