Coating apparatus having a cascade wall and metering blade, and a cleaning and recirculation arrangement for the coating apparatus |
摘要 |
An apparatus and method for applying at least one solution of a predetermined viscosity to photosensitive material. The apparatus includes at least an application roller that applies the coating solution onto the photosensitive material. The application roller partially extends into a solution tray of the coating apparatus and is partially submerged in solution in the solution tray. In an arrangement of the present invention, a cascade wall and metering blade are positioned within the solution tray so as to define a first section at which solution enters the tray, and a second section which receives solution that spills over from the first section and includes a port which leads coating solution back to a coating solution tank for recycling or leads cleaning solution to drain. The apparatus further includes a washing arrangement that washes the coating apparatus in an efficient manner. The washing arrangement includes a retractable scrubber bar arrangement that moves away from the application roller when the coating apparatus is in a coating mode of operation and is movable toward the application roller by way of brushes in a cleaning mode of operation. The apparatus and method further includes a recirculation system that alternatively supplies coating solution to the coating solution tray and cleaning solution to both the solution tray and washing arrangement.
