    Abstract: The inventive method produces round parts consisting of profiled metal sections from a straight, profiled extruded section forming a wheel-like shape having butt ends joined together by welding. Bending the straight section into a round part is accomplished by first adjustably prestressing the straight section and then subjecting the prestressed section to a rolling bending operation. For this purpose, the section to be bent is wound either from one side or from both sides around the outside diameter of coordinated rolling dies the rotating rolling dies being able to additionally perform a translatory motion in the direction of the longitudinal axis of the section. The resulting wheel rim has the rim pan integrally joined to the rim ring.

    Abstract: An improved method of stress rolling a metallic rim includes the additional step of applying an outside force to the rim to produce tensile stress in the region which is being stress rolled to produce a higher resulting compressive stress within the region than could otherwise be obtained through normal stress rolling.

    Abstract: A method for manufacturing a vehicle wheel is suggested in which the vehicle wheel can provide function and effect of preventing molding defects during molding of an outer rim portion and/or an inner rim portion having sound absorbing spaces 25 and of reducing acoustic cavity noise that occurs in a tire-internal space by use of the sound absorbing spaces. After a separation groove having a curved shape groove bottom surface 55a is formed between a ring-shaped wall portion and partition wall portions, the ring-shaped wall portion is bent toward a flange portion, and the ring-shaped wall portion and the flange portion are welded together. The sound absorbing spaces which communicate with each other via communication gaps defined according to the separation groove are thereby formed in the outer rim portion and/or the inner rim portion. In such a method, since the communication gaps can be stably formed, an increase in internal pressure caused by heat expansion of air in the sound absorbing spaces during a heat treatment step can be reduced, thus allowing prevention of molding defects due to the increase in the internal pressure.
