<p>The invention provides an apparatus for correcting C-bending. No matter band steel is bent in an upwards-protruding state or a downwards-protruding state, C-bending can be corrected. The apparatus for correcting C-bending comprises a pair of first correcting rolls (2) which are disposed in a way that the axis extend in the plate width direction on one plate face of the band steel (S), and the band steel (S) can be pressed from one plate face of band steel (S). The apparatus also comprises a pair of second correcting rolls (3) which are disposed in a way that the axis extend in the plate width direction under the first correcting rolls (2) on the other plate face side of the band steel (S), and the band steel (S) can be pressed from the other plate face of band steel (S). The axis of the first correcting rolls (2) and the second correcting rolls (3) are allowed to up-down incline in a left-right symmetrical manner by taking the approximate central position in the plate width direction of the band steel (S) as the center. According to the bending direction of the band steel (S), the apparatus is capable of allowing the first correcting rolls (2) and the second correcting rolls (3) to incline and be reversely rotated up and down.</p> |
