Abstract
A method of manufacturing seamless wheel rims while maintaining a predetermined outside diameter dimension and predetermined cross-sectional shape of the rims at a high precision, without requiring any correcting work. A ring-shaped material is interposed between a rotatable die having a surface corresponding to an outer peripheral shape of a wheel rim and a rotatable pressing roll provided within the die, either of the die or roll is driven to rotate, and the pressing roll is moved toward the die so as to roll and shape the material, while restraining the outside diameter dimension by the die.
