PURPOSE:To prevent the buckling of a rolling material by restraining the increase of its deformation due to edging, and to increase the rolling reduction in the width direction, by biting the material to vertical rolls while producing its deformation by slightly raising its both ends as well as supporting its central part by a roll table, in rolling a material by using an edger. CONSTITUTION:A pair of vertical rolls 3 is vertically installed at both sides of a roll table 2 used for conveying a rolling material S; and the lower end of a slant part 5 of roll 3, formed by continuously unifying a lower-side flange 4 and the slant part 5, is positioned on the same level as that of the pass line of material S or on the level of the lower side of material S. Therefore, the lower edges of both side ends of material S collide against the parts 5 during rolling, and said both side ends are raised to the small-diam. parts of parts 5 to deform the material S into a downward projecting form. This deformation tends to increase when the material S' is edged in this state, but the increase of this deformation is restrained and the deflection of material S' is limited because the central part of material S' is supported by the table 2. |
