PCT No. PCT/DE81/00166 Sec. 371 Date Jan. 25, 1982 Sec. 102(e) Date Jan. 25, 1982 PCT Filed Oct. 3, 1981 PCT Pub. No. WO82/01142 PCT Pub. Date Apr. 15, 1982.Apparatus for manufacturing wheel rim blanks from flat metal strip includes a plurality of work stations through which the metal strip passes to produce a cylindrical ring having a longitudinal axis and a welded joint. The work stations include a strip feed station, a cylinder forming station, a joint orientation station, a joint welding station and finishing stations. The work stations are arranged in a generally Z-shaped configuration with end legs extending in opposite directions from opposite ends of a transverse connecting leg. The strip feed station is located along one end leg, while the finishing stations are arranged along the other end leg. The ring forming, joint orientation and joint welding stations are aligned in succession along the connecting leg. The ring members are received in upwardly open U-shaped supports at the finishing stations and are moved in arcuate paths from the welding station through the finishing stations by an overhead conveyor device.
