Abstract
Set points for thicknesses of coatings on opposite sides of a sheet are determined in response to measurements of the thickness of each coating. A computer responds to the two thickness measurements to derive indications of the spread of values of the measurements for each coating. The computer derives an additional indication of the spread of values for the total thickness of the two coatings. In response to the indications of the spreads of values for the coatings and the total coating thickness, minimum allowable average values for the two coating thicknesses and the total coating thicknesses are determined. The set point values for the two coating thicknesses are calculated from these minimum values, with consideration given to predetermined maximum and minimum ratios of the two coating thicknesses.
