Abstract
PURPOSE: To control paint film thickness with good stability by correcting the rate of dilution used for the calculation of the film thickness by expressing it in term of rate of dilution successively at the time of controlling the film thickness in accordance with the estimated dry film thickness determined by expressing the detected wet film thickness in term of the rate of dilution.
CONSTITUTION: The wet film thickness detected with a film thickness detector 22 is expressed in term of a rate of dilution in a converter 24, and estimated dry film thickness is determined. This estimated dry film thickness and set film thickness are compared in a comparing operator 33, by which the rotating speeds and gaps of rolls 6W8 are regulated and the film thickness is controlled. At this time, the rate of dilution used for the conversion is corrected successively by comparing the film thicknesses of wet and dry states detected with film thickness detectors 22, 23. In this way, the paint film thickness is controlled with good stability.
