摘要： PROBLEM TO BE SOLVED: To exactly form a complicated or largely deformed portion on a material to be formed.
SOLUTION: In a press forming apparatus, respective rollers of a plurality of first group rollers and respective rollers of a plurality of second group rollers are alternately arranged in the longitudinal direction of the material to be formed. In the first stage, the respective rollers are turned at the ordinary rotational speed corresponding to the speed of the material to be formed moving in the longitudinal direction, and the forming portions of the respective rollers form deformed portions on the material to be formed. In the second stage, with respect to the respective rollers, the positions of the deformed portions of the material to be formed are detected, wherein the deformed portions are formed by the roller located on the just upstream side in the same group as that roller, and then, the modified rotational speed of the respective rollers necessary for matching the forming portions of the respective rollers with the deformed portions of the material to be formed is calculated based on the detected positional information, and the respective rollers are turned at the modified rotational speed without bringing the forming portions of the rollers into contact with the deformed portion formed by the roller located on just upstream side in the different group. In the third stage, the deformed portions of the material to be formed are furthermore deformed by the forming portions of the respective rollers by turning the respective rollers at the ordinary rotational speed. The second stage and the third stage are repeated.
