Abstract
A material to be shaped is reduced and formed by bringing dies with convex forming surfaces, when viewed from the side of the transfer line of the material close to the transfer line from above and below the material in synchronism with each other, while giving the dies a swinging motion in such a manner that the portions of the forming surfaces of the dies, in contact with the material are transferred from the upstream to the downstream side in the direction of the transfer line.
