Abstract
Wheel rim blank manufacturing apparatus comprises an elongated mandrel passing through Coiling, Welding and Machining Stations. Flat stock is fed transversely for coiling to cylindrical rim blanks about the mandrel. A transfer slide advances and maintains orientation of coiled rim blanks from the Coiling Station to the Welding Station. At the Welding Station clamps secure the blanks for resistance or high frequency current penetration welding. Internal clamps at the Welding Station have small shoulders for transferring the blanks past a Machining Station where a scarfing tool engages their welded areas. The method includes feeding stock transversely, coiling about a mandrel, advancing blanks along the mandrel, welding, again advancing the blanks, and machining weld areas.
