It is possible, in a rolling method of a strip shifting one-side-tapered work rolls in the axial direction and causing the upper and the lower work rolls to cross each other, to appropriately set a quantity of shift and a crossing angle and to improve an edge drop satisfactorily, by utilizing the relationship of the three factors including the quantity of shift and the crossing angle for determining quantities of operation necessary to correcting an edge drop of the strip and the quantity of correction of edge drop corresponding to these quantities of operation in the form of the relationship between the roll gap between the upper and the lower work rolls and the quantity of correction of edge drop, by providing an effective roll gap reference position apart from the strip edge by a prescribed distance.
