Abstract
Procédé pour fabriquer un cylindre écroui. Le cylindre est serré entre deux brides annulaires dont les alésages sont ferlés par une tige traversant axialement les deux brides et le cylindre, et qu'ensuite le volume entre le cylindre et la tige est soumis à l'action d'un liquide sous pression. Applications à la fabrication de rotors de turbogénérateurs.
