Abstract

Appareil de formation d'un empilage de feuillets magnétiques destiné à constituer une partie d'une machine dynamoélectrique. Il permet de poinçonner des feuillets comportant des ouvertures et des saillies sur une partie de la feuille de métal de façon à réaliser un empilage de feuillets enclenchés. Le premier feuillet comprend une ouverture de traversée sans saillie de façon à constituer le premier feuillet de la pile dont la surface est lisse. Les saillies de chaque feuillet suivant pénètrent dans l'ouverture du feuillet précédent et s'enclenchent dans celle-ci. Application à la formation du rotor ou du stator d'un moteur électrique.
