ABSTRACT OF THE DISCLOSURE: A plurality of roll stands are arranged along a planned passage line of a roll material. Each of the roll stands is provided with a pair of rolls each of which is formed, on the outer circumferential surface thereof, with a groove for rolling. The bottom surface formed on each roll is a circular arc in cross section. Both side surfaces of the groove are, in cross section, circular arcs of a radius larger than that of the bottom surface or segments of line. The roll material transferred along the planned passage line is passed between the grooves on the pair of rolls in each roll stand. Thus, the roll material is rolled. In this case, even if the thickness of the roll material deviates, it can be rolled into a finished material of a prescribed dimension.
