Abstract

PURPOSE: To improve the productivity of the blank wheel of tubeless wheels by applying pressing and rolling to the ring part of the cup-form molding obtained by the process similar to that for a tubed wheel thereby molding the same to the shape corresponding to the product.
CONSTITUTION: The required portion of the cup-form molding 5 obtained in the manner similar to the process for a tubed wheel is pierced. Thence, the ring part 5 is drawn-in toward the inner side from the outside surface by a conical die 8 and its over-drawing is prevented by a lower die 9. This yields the 2nd molding 10 which coincides with the minimum diameter part Wa of the ring part of the final product W. Following to this, the ring part 10a of the molding 10 is spread outward by press upper and lower dies and is then rolled to flare its opening side part 10b, whereby the blank wheel for tubeless wheels of the shape corresponding to the final product W is provided.
