A material 1 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 1, close to the transfer line from above and below the material 1, 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 1, are transferred from the upstream to the downstream side in the direction of the transfer line.

1. A plate reduction press apparatus comprising:dies arranged above and below a slab; sliders provided for each of the dies so that the dies can be moved up, down, and backwards and forwards with a swinging motion; and a driving device for driving the sliders, in which each one of the sliders is comprised of a main unit with a circular hole with center lines in the lateral direction of the slab, and a crank with a first axis engaged with the circular hole and a second shaft with a diameter smaller than the diameter of the first shaft and a center line offset from the center line of the first shaft, and the second shaft is rotated and driven by the said driving device, and in which a plurality of circular holes and a plurality of cranks arranged in the sliders are arranged in a row in the transfer direction of the slab, and constructed in such a manner that each crank produces pressing force.
