ABSTRACT:
A press working apparatus has a press machine provided with a pair of press dies. The press machine presses a preheated metal slab being transferred in a feeding direction with the press dies mutually opposed to press the metal slab in a direction perpendicular to the thickness of the metal slab. Each press die has a pressing surface facing a respective surface of the metal slab. The pressing surface of each press die has a predetermined length extending in the feeding direction of the metal slab. At least one of the pressing surfaces has a cross section perpendicular to the feeding direction of the metal slab. The shape of the cross section gradually changes along the feeding direction of the metal slab so as to have a predetermined sectional shape for forming the metal slab into a required sectional shape. At least one surface of the metal slab is gradually formed into a predetermined sectional shape as the metal slab is passing through the press machine.
