PROBLEM TO BE SOLVED: To provide a paint feeding device and a paint feeding method wherein the swell of a coating pattern is less liable to be generated by using a cylinder when a substrate is intermittently coated with a paint. SOLUTION: The paint is fed to alternately two cylinders 5, 10 through a three-way valve 3 from a paint tank 2 storing the paint. The paint accumulated in the cylinders 5, 10 is charged to a coating head 18 through their corresponding stop valves 4, 9 to coat the substrate 19 therein. The stop valves 4, 9 are alternately opened or closed and the stop valve of the cylinders receiving the paint from the paint tank 2 is closed. Controlling both the stop valves 4, 9 in the closing state cannot charge the paint to the coating head 18 during this time to form blank parts on the substrate 19. COPYRIGHT: (C)2005,JPO&NCIPI |
