ABSTRACT:
A method for manufacturing a one end flange-less wheel rim includes the steps of: providing a sheet of rim material having a width substantially corresponding to the developed width of a one end flange-less wheel rim to be made, curving the sheet to form a cylinder, flaring one end of the cylinder, roll-forming the flared cylinder to the desired rim configuration using roll-forming machines each including an upper roll, a lower roll and a ring, with the flange-less side end of the rim material being axially abutted against the ring, and removing a margin for machining from the flange-less side end of the rim material. In the apparatus, the ring is coupled to one of the upper roll and the lower roll.
