Abstract

A pair of rolls (11, 12) displaceable axially in accordance with rolled sheet width are arranged at the upper and/or lower sides of a pair of work rolls (2, 3) having a high flexural rigidity, such that the axes of the axially displaceable rolls (11, 12) are substantially in the same plane as the axes of the work rolls (2, 3), so that the shape control of the rolled sheet (1) is performed by the axial adjustment of the axially displaceable rolls (11, 12). Each axially displaceable roll (11, 12) has an axial end portion the diameter of which is gradually decreased toward the axial outer extremity with such a rate that the reduction in radius of said axial end portion within the range of 100 mm is at least 0,3 mm. Stress concentration at the displaceable roll (11, 12) end, spalling and scoring are avoided, and the shape controllability is improved considerably.
