A multi-stage roll mill for producing a lengthy continuous rolled sheet material by a one-pass operation, comprises a driven central working roll, and a plurality of peripheral working rolls arranged spaced apart and on the periphery of the central working roll, the diameter of each of the peripheral working rolls being much smaller than that of the central working roll. Each peripheral working roll has a screw-down mechanism which is capable of freely adjusting the gap between the periphery of the peripheral working roll and the periphery of the central working roll. The peripheral working rolls are arranged in such a manner that the work being held in the gap between the peripheries thereof and the periphery of the central working roll is subjected to continuous multi-stage rolling.
