あった。(Problems to be Solved by the Invention) In the conventional device, when the clamper moves a certain distance, the drive device is stopped by a limit switch or the like for correction. However, if the metal strip M has curls or waves, the desired amount of correction cannot be obtained. That is, the distance between the clamps is L, and the moving distance of the clamp A is 1. , the actual length of the metal strip M between the clamps is L + △L, the desired elongation ε to be given to the metal strip M for straightening, and the actual elongation rate fto, then OC=□ (winter). If the metal strip M has curls, waves, etc., the desired amount of correction cannot be obtained, and the value of ΔL differs depending on the situation of each metal strip to be straightened, so it is not possible to obtain the entire metal strip with stable quality. However, there was a problem in that metal strips were overextended or undercorrected.

ようＶこした。(Means for Solving the Problems) In the present invention, both ends of the metal strip are clamped by clampers, and a driving device is used to move the clampers to widen the distance between them to straighten the cup of the metal strip. In this case, a detector is provided to detect the force by which the drive device moves the clamper, and the distance between the clamper and e is measured when the detected value of the detector reaches a predetermined value. In addition, the above-mentioned problem was solved by providing a distance control device that stops the driving device when the distance between the cranks expands by the tensile distance obtained by multiplying the measured value by the desired elongation rate.

合を解決出来る。(Function) One of the clampers clamping each end of the metal strip, the distance l? When I is moved to spread out, the distortion of the metal strip is corrected, but if the metal strip is unwound or wavy, the crank A applies a large negative load to the drive device until the unwound, etc. is restored. When the metal strip moves smoothly and any curls are removed, a strong force starts to be applied from the drive device to stretch the metal strip. This change in force is detected by a detector, and when the first detection reaches a predetermined position where the metal strip is fully extended, a distance control device measures the distance between the clampers and adds that measurement value to the metal strip. The total tension distance is calculated by multiplying by the elongation rate desired for correction of the distance, and when the distance between the clamps further increases by the tension distance based on the measured value, the distance control device stops the drive device f. Therefore, it is possible to correct the distortion by giving the desired elongation to the heavy metal strip without being subject to large or small defects such as curling of the metal strip, and it is possible to solve the problem of overstretching or insufficient straightening.

However, if the metal strip (1) has curls etc. At 1, when the unwinding etc. are settled, a relatively small force is applied to the clamper (the force is moved, and after that, a strong force is applied to the clamp flap 7 to give the material of the metal strip (1) the corrective elongation). , a change in force as shown by curve F in FIG. 4 is detected by the detector OD. In addition, the distance between the clampers e (6) and (7) in this case is initially L, and when the curl of the metal strip (1) is removed, it is L + Δ.
It becomes L. When the detected value at the detector 0D reaches a predetermined value of 1 straight ΔF, which is calculated by adding mechanical friction to the strong force for correction, the distance control aH+ta2 becomes 7/R(61(7)
Measure the distance IL + ΔL' between them, and calculate the measured value (L+ΔL
