Abstract
PURPOSE: To enable on-line thickness control of an applied paint film, in a film thickness controller for high-speed continuous coating, by measuring the thickness of the applied paint film in a wet state with a film thickness gauge, obtaining the average value of a plurality of the films by a computing circuit, and feeding back the averaged value.
CONSTITUTION: When a sheet 1 passes through a probe 7 and a photosensor 8, its thickness is continuously measured with a wet film thickness gauge 10 using ultrasonic wave or the like. The measured value is inputted into a data-forming circuit 11, and then read, in company with a signal from a pulse generator 9, in the first averaged applied paint film thickness calculating circuit 13 through a data-reading circuit 12 to calculate an averaged thickness for one sheet. The thicknesses for a plurality of sheets are successively memorized in the second averaged applied paint film thickness calculating circuit 14 which outputs a ground averaged value. The ground averaged value is compared with an output from a setter 16, which sets the upper and lower limits of the paint film, in a comparing circuit 15. When the ground averaged value is beyond the boundary, a gap control signal is fed to a roll gap-control system 30 and compared with a signal from a roll gap gauge 19 to control the gap.
