Abstract

L'invention a trait à la perforation de bandes métalliques. Elle a pour objet un procédé de réalisation de nombreuses perforations fines dans une bande de métal mince par passage de la bande entre une paire de rouleaux tournant en permanence, chacun réalisé avec des rangées circonférentielles de dents alternant avec des rainures circonférentielles, les rouleaux étant montés de sorte que chaque rangée de dents sur un rouleau fasse saillie dans une rainure de l'autre rouleau, et agencés pour tourner de sorte que chaque dent d'un rouleau soit circonférentiellement en face d'un intervalle entre des dents adjacentes de l'autre rouleau. Application : fabrication de plaques d'électrode d'accumulateurs.The invention relates to the perforation of metal strips. It relates to a process for producing numerous fine perforations in a thin metal strip by passing the strip between a pair of permanently rotating rollers, each made with circumferential rows of teeth alternating with circumferential grooves, the rollers being mounted so that each row of teeth on one roller protrudes into a groove of the other roller, and arranged to rotate so that each tooth of one roller is circumferentially opposite a gap between adjacent teeth on the other roller. Application: manufacture of accumulator electrode plates.
