A four-high rolling mill stand has each work roll mounted to the free end of a preloaded drive shaft rotatably carried in an individual arm pivotally mounted in the mill frame. The effective position of the pivot axis of one arm is movable through a limited arc relative to the pivot axis of the other arm by means of limited rotation of eccentric pivot pins, whereby to effect adjustment of the axial position of the work rolls relative to one another to avoid ovality or assymetry in the rolled stock. |
