Abstract:
A steel flanged wheel rim includes a pair of hollow ears extending radially and outwardly at the side edges of the rim, a semi-circular recess between the ears and a flange extending radially and inwardly from the center of the recess. The steel flanged wheel rim is produced by plastically processing through a series of shaping rolls in different processing stages and then bending the band into a ring shape to thereby continuously produce steel flanged wheel rims.
