PROBLEM TO BE SOLVED: To provide a shape straightening device capable of easily and individually adjusting the distance between upper and lower straightening rolls on the DR side and the OP side. SOLUTION: The distance between a first frame 52 to support an upper straightening roll 51 and a second frame 54 to support a lower straightening roll 53 is detected by first and second distance detection means 55 and 56 on the DR side and the OP side of the straightening rolls. For example, when the distance on the DR side is larger than the distance on the OP side, a shaft coupling 61 is uncoupled, only a first screw-down means 57 provided close to the DR of the second frame is singly operated and elevated to make adjustment so that the distance on the DR side and the distance on the OP side are equal to each other. Next, the shaft coupling 61 is coupled, and the first and second screw-down means 57 and 58 are interlocked with each other. The distance is freely changed while maintaining the balanced condition, and the shape is straightened corresponding to steel strips of different thickness. COPYRIGHT: (C)2006,JPO&NCIPI
