Abstract
PURPOSE: To rim for bicycles of lightweightness, consistent quality and high strenght which is obtainable by opposedly pressure-contacting a pair of rolling rollers on the inside and outside surfaces of a seamless blank ring made of steel of a small diameter and large thickness while turning the same to form the rim blank of the specified size then forming the same to a desired sectional shape by forming rolls.
CONSTITUTION: A seamless blank ring 2 of a small diameter and large thickness composed of carbon steel or stainless steel is disposed between a pair of rolling rolls and is rolled while revolving the rolls in the opposite directions and pressing these with each other. While the resultant rim blank 3 of the specified size is being passed between a pair of forming rolls, it is subjected to plural stages of plastic working, whereby it is formed to a rim 1 having a desired sectional shape. Since this rim does not required welding, it has no seams where concentrated load occurs, is high in mechanical characteristics and is consistent in quality.
