PURPOSE:To improve width accruracy and product yield by performing edger rolling by slanting vertical rolls to the direction, reverse to the advancing direction of a rolling material, in the vertical plane parallel to the advancing direction of the material. CONSTITUTION:A pair of vertical rolls 1 having smooth surfaces are previously slanted to the direction reverse to the advancing direction of a rolling material S by a proper angle theta deg., and the material S is bitten by the slanted rolls 1. The rolling material S bitten by the rolls 1 is subjected to rolling reduction in the width direction under the rolling load of rolls 1, to produce deformation curved downward. The deformation of material S is counter held by a table rolls 2 disposed between the rolls 1, and the edging is performed while balancing a bending moment, produced in the material S at the time of edging, by the roll 2. |
