Method and apparatus for laminating a metal plate material.

A rolling method of a flat-rolled metal material, for carrying rolled out using a rolling mill having at least work rolls (1, 2) and rollers reserve (3, 4) for the flat-rolled metal material, which characterized in that the above method comprises the steps of: measuring the force in the rolling direction acting on the roller blocks (5, 6) on the operator side and the driving side of said work rolls; calculating the difference of the force in the rolling direction between the operator side and the driving side; and control the left-right distance between rollers of said rolling mill on the basis of said difference rotary component.
