Abstract

L'invention concerne un procédé permettant de refendre une feuille métallique, ainsi qu'une machine à refendre des feuilles métalliques pouvant supprimer facilement et de manière sûre l'apparition de poudre sur une feuille métallique, telle qu'une feuille de cuivre. Le procédé selon l'invention consiste à découper une longue feuille métallique acheminée en continu au moyen d'une lame de réception disposée sur un rouleau rotatif, cette lame étant associée à une lame de refendage de type disque, et à appliquer simultanément un solvant organique au moins sur le bout de la lame d'une partie ajustée sur la lame, disposée sur la partie d'extrémité périphérique extérieure de la lame de refendage. L'application de solvant organique sur le bout de la lame permet de supprimer l'apparition de bavures et de poudre sur la surface de coupe de la feuille métallique, et de réduire l'usure à l'endroit où la lame de refendage vient en contact avec la feuille métallique, pour éviter que la feuille métallique s'allonge, ce qui empêche l'apparition de bavures et de poudre.
