Abstract
PURPOSE:To make controlling of a wide range with high accuracy possible and to reduce rolling force by deviating an intermediate roll and a work roll in contact with the intermediate roll in upper and down stream directions of a rolling line and to control these from a horizontal direction. CONSTITUTION:When a part of a divided lateral supporting roll 8 is pressed strongly to a lower work roll 2, the deflection of the roll 2 of that part is reduced, by which the clearance between the upper, lower work rolls 1, 2 is reduced and the thickness of a rolling material 6 in said part is reduced. If a part of a divided lateral supporting roll 9 is pressed strongly to an intermediate roll 5, the deflection of the roll 5 in said part is reduced, and this results in that the roll 2 is pressed to the roll 1. The thickness of the material 6 in that part is reduced, and the thickness in the width direction is adjusted freely in each part. The thickness in the entire part in the width direction of the material 6 is regulated by pressing and detaching the divided rolls 10 of the rolls 8, 9 simultaneously.
