Abstract

L'invention concerne les pièces annulaires, du type diaphragme, comportant une partie périphérique 10 formant rondelle Belleville et une partie centrale il fragmentée en pattes radiales 12 par des saignées 13. Suivant l'invention, pour l'obtention d'une largeur réduite pour l'extrémité ouverte 15 de telles saignées, on réalise en deux opérations distinctes les deux bords de ses saignées, à savoir une première opération de tranchage au cours de laquelle on réalise d'abord l'un de ces bords, puis une deuxième opération de tranchage au cours de laquelle on réalise l'autre de ceux-ci. Application notamment aux diaphragmes d'embrayage pour véhicules automobiles.
