Summary:An automatic gauge control is disclosed to provide on line control of the delivery gauge or thickness from at least one roll stand of a tandem rolling mill, for which one roll stand it is not desired to adjust the roll opening for the purpose of controlling the delivery gauge of workpiece strip leaving that roll stand. The gauge error of the workpiece strip leaving that one roll stand is corrected by predetermined adjustment of a selected previous roll stand in relation to the work-piece gauge error measured at that one roll stand and to provide a desired entry gauge correction in relation to that one roll stand.
