CONSTITUTION: A strip shaped or a rolled raw material 1 cut into a necessary width is formed by plural number of rollers 2 with different feed rates to match the sectional shape of the edge. Afterwards, a linear shaped continuous formed product 3, formed by forming machine, the feed rate of every roller of which is determined so as to form the arc shaped formed product with a constant radius, is obtained. this product is cut into a length to correspond to the diameter, and a final formed product 4 is obtained by sticking an end tip together. By using such a way, a material loss is reduced, and the edge shaped formed product with different diameters is obtained by only changing the feed rate of the roller as far as the sectional shape is same, and an advantage such that a continuous forming is possible and so on, is acquired.
