ABSTRACT:
An equipment for the manufacture of ring members for vehicle wheels starting from metal plate strip cut lengths, which mainly comprises a cylinder bending station formed by a calender, a welding station formed by two discontinuous type welding machines with rollers (which carry out a so-called "ecrease" welding in which the overall lap joint thickness is reduced plastically to about the thickness of one of the lapped end edges), each having a grasping device, intended for grasping the workpiece, movable between an extracted position, in which it extends into the bending station to grasp the workpiece lying therein, and a retracted position, and a rolling station which comprises a pair of rollers, one of which is driven; the welding station is arranged to move, during the welding step, between a first position, in which the first welding machine faces the bending station, and a second position, in which it faces the subsequent rolling station, and the two welding machines alternate in the two mentioned positions; the rolling station is intended to work on the ring members delivered by the welding station while these ring members are still hot in consequence of the welding they have been subjected to.
