Abstract

L'invention concerne une poinçonneuse qui peut faire des rangées de trous avec des écarts irréguliers. Pour ontenir ce résultat, l'outil ne porte qu'un nombre restreint de poinçons; la bande avance régulièrement à une cadence déterminée et, selon les ordres reçus par un dispositif électronique commandé par carte perforée, l'outil ne s'abaisse qu'aux moments voulus. Une utilisation particulièrement intéressante se trouve dans la fabrication de tuyaux perforés pour pots d'échappement.
