<p>A method and apparatus for determining the initial opening of a pair of opposed work rolls utilized to reduce the thickness of a metal workpiece provides that selected readings of the roll separation force occasioned by passage of the workpiece through the rolls on a next preceding pass are utilized to determine the initial roll opening setting for the next pass of the workpiece between the rolls. The readings selected differ in accordance with a determination of whether or not the next pass is to employ automatic gage control.</p> |
