A rolling mill stand, under particularly tandem workpiece rolling conditions where more than one workpiece passes through the stand for a given setting of that stand, is provided with a control system including a plurality of workpiece position sensors operative such that after a given workpiece has passed through the rolls of the mill stand the presence of any additional workpiece also desired to be passed through the stand with the same roll opening setting is sensed before the roll opening of the stand is changed to the next desired setting for any scheduled next workpiece passage through the stand.
