Moreover, in the said patent document 2, a pair of upper and lower rotary blades are made to oppose both surfaces of a steel strip, and a shearing process is performed. Therefore, in order to form a disk-shaped part, it is necessary to separate a pair of upper and lower rotary blades, and then again to make a mechanism that faces each side of the steel strip again, which complicates the apparatus and is not excellent in productivity. .
