Next, the timing that the longitudinal position of the metal strip in the neighborhood of the welded portion arrives at upper and lower work rolls of a roll cross rolling machine is recognized based on the tracking information of the welded portion. At the same time, the magnitude of modification for the cross angle at the longitudinal position is transmitted to the roll cross control apparatus on the stand of the roll cross rolling machine so as to modify the cross angle.
