In a tandem type rolling mill, it is difficult to control each roll bending force so as to produce a constant forward slip and a constant backward slip at each stand in the transversal direction. A first shape meter is disposed between a pay-off reel and a first stand and a second shape meter is disposed between a tension reel and a last stand. The roll bending forces under the first stand, the second stand, . . . the lth stand are controlled so as to produce a constant backward slip at the first stand as measured by the shape meter disposed between the pay-off reel and the first stand to provide a predetermined value. The roll bending forces under the first stand, the second stand, . . . the lth stand are also controlled so as to provide a constant forward slip at the last stand as measured by the shape meter disposed between the last stand and the tension reel to provide a predetermined value. The feeding of a roll coolant is also controlled together with the control of roll bending forces.
