Abstract (en)
[origin: EP0808677A1] A method and machine for manufacturing compression rings in which flat band material is fed to a stamping station (40) from a feed station (10), a blank is stamped out with a mechanical connection having male and female configurations (400, 420) at opposite ends, the blank is then fed to a deformation machine (50) where it is displaced into the several axial positions of the machine in which, in a first position, the blank is predeformed into configuration permitting closing of the mechanical connection in a second position in which the blank is also deformed into its circular configuration. Preferably the thus-deformed and closed compression ring is then subjected to a swaging action in a third position before it is ejected out of the machine. <IMAGE> <IMAGE>
