れている。Since the conventional shape control is configured as described above, the tension set value by the tension reel (6) differs depending on the plate thickness and plate material of the rolled material (1). The plate is pulled due to the tension value, and the detection of the plate shape is not constant, and the gain of the control system must be kept low, weakening the control effect.

形状制御が行なわれる。In the plate shape control device of the present invention, presser rolls are installed before and after the plate shape detector, and the presser rolls perform line cutting and keep the tension of the rolled material in the area where the plate shape detector is installed at a constant value. Therefore, shape detection accuracy is improved and accurate shape control is performed.

状制御性悪化を防止している。A presser roll ω, (32) and a loop car (31) are installed before and after the shape detector (6), and a tension meter (9)
Depending on the output value, the loop car (31) and presser roll (
32) by controlling the position and speed of each of the shape detectors (
δ) Keep the tension of the rolled material (1) constant at the installation part. Since the tension in this part is constant, the shape detector (5
) allows highly accurate shape detection without being affected by changes in system tension. In other words, by eliminating interference with the tension of the tension reel (6) and the exit tension of the final stand (γ),
This prevents the conventional deterioration in shape controllability caused by changes in tension due to plate thickness and plate material.

また、ループカーを省いた簡易形についても、同様な効
果が得られる。Furthermore, a similar effect can be obtained with a simplified version that does not include a loop car.
