Claims4
A method for the manufacture of a spoke for spoked wheels including forming a head of said spoke at at least one longitudinal end of the shank thereof by means of an equipment for the plastic deformation of the end of the shank, the equipment comprising a calibration station which comprises a pair of counter-rotating gauging rollers and a rotating center;
- wherein said plastic deformation is obtained by maintaining the counter-rotating gauging rollers in rotation with a free rotation of the spoke between said counter-rotating gauging rollers and by holding the spoke against the surface of the counter-rotating gauging rollers by the rotating center urging on the at least one longitudinal end of the shank of the spoke.
