A roll bending apparatus comprising:
- a roll set frame movably installed;
- and
- a bending frame having a plurality of bending rolls bending a material, and rotating on the roll set frame to adjust positions of the plurality of bending rolls.
A roll bending method comprising:
- a material entry operation of moving a material and inserting a tip of the material between adjacent bending rolls of a bending frame;
- a first bending operation of moving a moving frame of a roll set frame in a material supply direction, supplying the material while rotating the bending frame in a first direction, and bending a first transition zone of the material;
- and
- a second bending operation of supplying the material while stopping movement of the moving frame and stopping rotation of the bending frame, and bending a target curvature zone of the material after the first transition zone.
