Curvature forming method and equipments for plate

Here, a method for forming the curvature of the plate material by using a first and second rolset with one driving rolyeol between two idle rolyeol is disclosed. The disclosed method, the first driving roll rolset column and the position offset from the drive rolyeol 2 rolset to the direction of movement of the plate member; Rolset the first and the second supporting the plate member proceed on rolset between the driving rolls of the second column and idle rolyeol rolset; Comprises urging the sustained between the binary portion of the plate member to the drive of the first rolyeol rolset. Rolset linear array, a drive, idle, progression, plate material, curvature, shaping
