Abstract (en)
A roll-bending process apparatus (100) including a pushing roll (10) having a cylindrical side surface and two receiving rolls (11 and 12) each having a cylindrical side surface is provided. The roll-bending process apparatus (100) bends a work (20) by pushing the pushing roll (10) toward the receiving rolls (11 and 12). The roll-bending process apparatus (100) forms a taper-shaped bending-formed article by adjusting a pushing amount of the pushing roll (10) so that a first pushing amount on one end side (10a) of the pushing roll (10) is different from a second pushing amount on the other end side (10b) of the pushing roll (10).
