There is provided a method for restraining deformation of a nip roll, in which polygonal deformation of nip rolls that are in contact with each other is restrained, so that vibration produced by the deformation is decreased. The diameter ratio between the first and second nip rollsandis set at a value different from 1, by which both of the numbers of polygon sides of the rollsandare prevented from becoming integers or values close to integers. Thereby, polygonal deformation of nip rolls that are in contact with each other, so that vibration produced by the deformation is decreased.
