PURPOSE:To level distortion of a steel plate surely without damaging projected stripes, by passing a steel plate provided with projected stripes etc. through multistage press rolls in which roll pairs of soft elastic material and hard material are combined. CONSTITUTION:Many press rolls A consisting of pairs of a hard material roll 1 and soft elastic material rolls 2 are arranged in the direction of feeding of a steel plate B, and a long continuous steel plate B is passed through these press rolls A. At this time, the part depressed by the hard roll 1 and released to the side is held by soft elastic rolls 2, and the steel plate B is bent partially and continuously, and lateral distortion is changed to longitudinal distortion. By this way, distortion of a steel plate B in which projected stripes are formed by bending and corrugation is formed by embossing can be leveled without deforming the projected stripes and crest parts of corrugation. |
