摘要： To a fulcrum roll unit portion in a workpiece, a corresponding initial curvature radius is applied, and to a bending roll unit portion in a workpiece, a corresponding design curvature radius is applied. To an intermediate unit portion in a workpiece, an intermediate curvature radius set so as to continuously change from the initial curvature radius to the design curvature radius is applied. At least one of the fulcrum roll and the bending roll is moved on the basis of an integrated value obtained by integrating the amount of change in bending position in each of the intermediate unit portion and the bending roll unit portion.
