ABSTRACT:
A coating apparatus in which a coating material is passed from an internal reservoir through a narrow orifice to a surface to be coated. At the end of the orifice the apparatus has two surfaces which are adjacent the surface to be coated, one of which is closer to the surface to be coated and functions as a metering surface. A reservoir of coating material is built up between the other surface and the surface to be coated and coating material is metered therefrom. The apparatus is particularly suited for applying an imaging suspension to an electrode of a photoelectrophoretic imaging system.
