A four-high rolling mill stand for rolling metal bar stock. Each work roll is carried by a work roll arm pivotably mounted about a first axis and each support or back-up roll is carried by a separate support roll arm, each support roll arm being pivotally mounted about a second and third axis respectively positioned on opposite sides of the first axis. The position of one or each of the second and third axes is adjustable to permit adjustment of the axes of the associated support or back-up rolls towards and away from the stock pass line. |
