Abstract (en)

[origin: EP3335814A1] In a manufacturing method of a thickness-varied metal plate, first, a cut plate (B) is manufactured by cutting a metal plate having a constant plate thickness into a predetermined shape. Next, the thickness-varied metal plate (TB1) is manufactured by rolling the cut plate (B) using a processing machine (10) including a pair of work rolls. Here, a radius of one of the pair of work rolls is varied in a circumferential direction and an axial direction. Accordingly, the thickness-varied metal plate (TB1) manufactured by rolling the cut plate (B) using the processing machine (10) has a plate thickness varied in two different directions orthogonal to a plate thickness direction.
