Abstract: A rolling mill stand having work rolls and back-up rolls extending from respective arms which are pivotally mounted, and including a pair of load cells recessed into one side of each work roll arm and a loading device recessed into the opposite side of each work roll arm. The load cells are spaced at different distances from the stock pass line, and the loading device is disposed on the centre line passing between the load cells. The arrangement is used for tension measurement in the rolled stock and minimizes errors arising from twisting of the work roll arms.

Abstract: A hydraulically operable device for stretching a hollow roll arbor to slightly reduce the arbor diameter in order to fit rolling sleeves around the arbor. The device includes a rod which is inserted into the hollow arbor and a hydraulically operable piston and cylinder arrangement at one end of the rod to apply a load through the rod to the arbor. A circular split collett extends around the piston and cylinder arrangement and engages at one end in a reaction block which reacts in response to the applied hydraulic pressure and at its other end with the roll arbor. The collett is held to the reaction block and to the arbor by annular rings, so that when a load is applied to the rod, the arbor is stretched longitudinally.
