PROBLEM TO BE SOLVED: To rationalize a both sides painting process for a porous plate having concaves and convexes in/on the surface.SOLUTION: A porous plate 1 is pre-heated by being carried into a pre-heating furnace by being put on a carrier roller 2 with its surface 2 being upward. Next, the porous plate 1 taken out from the pre-heating furnace is carried into a painting machine and spray painting is carried out on its surface. Next, the porous plate 1 is heated and dried by conveying the porous plate 1 on which the surface painting is executed into a drying furnace. Afterward, the porous plate 1 is upturned on the carrier roller 4, and the back surface of the upturned porous plate 1 is painted by using the painting roller 5. After painting this back surface, the porous plate 1 is cooled by applying an air blow to the porous plate 1 by conveying it into an air cooling apparatus provided with an air blower. |
