Claims

[Scope of utility model registration request]

In an apparatus in which one of a pair of upper and lower work rolls has a diameter smaller than that of the opposing work roll, and the large-diameter work roll is rotated by a main drive device for rolling, the above-mentioned large-diameter work is performed. A device is provided between the roll axle box and the upper and lower backing roll axle boxes to apply a vertical bending load to the large-diameter work roll, and the small-diameter work roll is moved in the rolling direction relative to the backing roll on the small-diameter work roll side. and on the offset side of the small body side work roll,
Equipped with a horizontal bending device that bends the small-diameter work roll as desired, and furthermore, a tapered sleeve is arranged around the outer periphery of the arbor on the backing roll on the small-diameter work roll, so that the tapered sleeve expands and contracts and has a variable crown amount structure. A rolling device characterized by using rolls.
