Abstract
PURPOSE: To prevent the hunting of a control system by comparing the detected paint film thickness after drying with prescribed film thickness, and transmitting the signal thereof to a painting section with the delay by the time when a steel plate moves from the painting section up to a film thickness detector.
CONSTITUTION: In a producing plant for painted strips by painting a steel plate 1 in a painting section 3, drying the paint with a dryer 4 and taking up the plate with a take-up roll 5, the paint film thickness after drying detected with a film thickness detector 22 is compared with prescribed film thickness in a comparing operator 23. At the time of controlling film thickness by transmitting the deviation signal from said comparing operator to the section 3, the transmission of said signal is delayed by the time required for the plate 1 for moving from the section 3 to the detector 22. Since in this way the timing of control is properly matched in a long production line as well, the hunting of the control system is prevented.
