Abstract
A roll for a rolling mill capable of an on-line control of the width thereof. The roll includes a drive roll connected to a mill motor and a hollow driven roll driven by the drive roll while being axially slidable with respect to the drive roll. A screw shaft is screwed to the inside of the hollow driven roll in such a manner that an end-to-end contact of the driven roll with the drive roll is obtained. A clutch is provided for a selective locking of the screw shaft, which is unlocked during a normal rolling process, so that the screw shaft is rotated together with the drive roll and the driven roll by a rotation of the mill motor. When adjusting the roll width, the clutch is operated so that the screw shaft is locked, and as a result, a rotation of the mill motor causes a mutual axial movement of the drive roll and driven roll to thus adjust the roll width. A means is also provided for a centering of the roll at the pass line of the material, after the adjustment of the roll width.
