<p>The apparatus has a flat type bending apron (3) mounted on a mold frame, where a plane of the bending apron is in contact with a radius surface (21) of the mold frame in a tangential direction. A metal plate (7) is arranged toward the mold frame. A metal plate pressurizing tool is arranged to continuously contact radius surface of the mold frame. A lever (4) is installed in a pressure cylinder (5) that is arranged to contact the bending apron. An outer contour line of the pressure cylinder is arranged corresponding to an inner contour line of a valley. An independent claim is also included for a method for deformation of a metal plate.</p> |
