A rolling process for forming a pulley (21) having one or more V-grooves (24) and an integral phonic wheel (23) in which a substantially cup-shaped, semi-finished product (17) having a base wall (18) and a substantially cylindrical lateral wall (19) is rotated and subjected to successive rolling steps consisting, in particular, of at least one first step of roughing the grooves (38), a step of finishing the grooves (24), and a step of forming toothing by the rolling of an annular portion (23) of the lateral wall (19) of the semi-finished product (17) defined during the previous steps; the steps of finishing the grooves (24) and the toothing are carried out simultaneously in the same rolling machine (1). <IMAGE> |
