ABSTRACT:
Rolling mills, especially for sheet metal, and also paper, rubber and similar rolling mills, require accurate control of the gap between the rolls since this determines the uniformity of the gauge of the material rolled by the mill. This invention provides a rolling mill with sensors that cooperate with the circumferential surfaces of the rolls, or rigid parts thereof, to detect relative movement of the rolls in directions that affect the roll gap and the gauge of the material being rolled. Response of the sensors operates a transducer to affect automatic correction of changes in the spacing of the rolls from one another.
