Abstract
PURPOSE:To manufacture titled rim wire with consistent hardness prossessing no surface flaw, by forming the round wire into a flat tape with specified section of approximate trapezoid shape, and next, by gradually bending both of the right and the left ends of the tape so as to form desired cavity inside. CONSTITUTION:The round wire is formed by the irregularly shaped roll or the irregularly shaped die into the tape 5 with desired flat section of approximate trapezoid shape. Hereupon, above formation is desired to make the sectional area of this approximate trapezoid shape section to be equal to the sectional area of the irregular U-shaped rim wire to be obtained by the final formation. Next, both of the left and the right ends of the tape 5 are gradually bent by the roll of irregular shape or the die of irregular shape so as to make the irregular shaped rim wire 7 possessing desired cavity 6 inside. Thus obtained rim wire 7 possesses no surface flaw and its material causes no hardening.
