PROBLEM TO BE SOLVED: To improve the quality of the surface of a sheet product finished by a multi-stage roll device. SOLUTION: One end part of the upper roll and the other end part of the lower roll of the roll device in which two rolls are disposed on the upper and lower sides are supported by bearings 3a and 4b in which 41 pieces of rollers 8 are assembled, and the other end part of the upper roll and one end part of the lower roll are supported by bearings 3b and 4a in which 42 pieces of rollers 8 are assembled. The number of rollers are differentiated between the bearings on the same right and left sides of both rolls and between both right and left sides of each roll. By this, the passing vibrations of the rollers 8 are not synchronized with each other between the bearings to improve the quality of the surface of the sheet product pressingly held by both rolls.
