PURPOSE: To prevent the uneven wear of roll by installing a moving device for moving a work roll in its axial direction in a roll chock to make the work roll movable in its axial direction.
CONSTITUTION: A rolling material 1 is rolled by upper and lower work rolls 2a, 2b which are crossing each other at a prescribed cross angle and upper and lower backup rolls 3a, 3b which are in contact with the outsides of rolls 2a, 2b respectively. Both ends of said rolls 2a, 2b are freely rotatably supported by a pair of roll chocks 4a, 4b and are mounted so as to be vertically movably in a housing 6. Further, the roll 2b is supported freely movably in its axial direction by the chock 4b, and a moving device for moving the roll 2b in its axial direction is also housed in the chock 4b. Thus, the uneven wear of roll is prevented by this device.
