Abstract: In an installation for reducing the thickness of material, the thickness reduction is controlled by computing systems based on equations in which the predicted thickness error is a function of the differential between the input and output lengths of a given volume of material passing through the installation. Greater accuracy may be obtained by disclosed modes of follow-on control. Procedures are discussed for recalibration of the systems.
