Meanwhile, the upper roller continue to add downward pressure on the roller, the upper roller moves back and forth on the plate. When the plate pass the bottom of upper roller (the roller deformation zone) in turn, and stress exceeds the yield limit, it will produce plastic deformation, the plate obtained the plastic bending deformation along the full length, and processed into the required shape.
