<p>A roller leveller (100) that levels a slab-like metal plate (P) is provided with: a plurality of leveling rolls (6, 8) that rotate to pass the metal sheet while sandwiching and pressing the metal plate (P); a hydraulic press cylinder (4) that presses the metal plate (P) via the leveling rolls (6, 8); driving devices (15) that rotate corresponding leveling rolls to pass the metal plate (P); and pinch rolls (31a, 31b) disposed on the outer part of the leveling roll arrangement site on the pass line of the metal plate (P). While the metal plate (P) is pressed via the leveling rolls (6, 8) with the required pressing force for leveling the metal plate (P) by the press cylinder (4), the metal plate (P) is passed by the pulling force generated by the pinch rolls (31a, 31b) and the drive force generated by the driving devices (15).</p> |
