ABSTRACT:
A reservoir for dipping a non-cylindrical flexible belt into a coating fluid so that an electrophotographic layer can be deposited onto its outer surface during a manufacturing process includes a non-cylindrical tank with an inlet located at one end. A coating fluid enters the bottom of the tank and moves past a flow divider located inside or just above the inlet. This divides the entering fluid into two substantially equal portions, so that the level of coating fluid inside of the tank rises uniformly. The coating fluid passes first through a porous membrane, and then through a perforated plate, both of which will reduce the velocity of the coating fluid, to ensure that the fluid has laminar flow characteristics once it reaches the top of the reservoir. Finally, the coating fluid passes through an annular shaped flow director which ensures that the layer which is deposited onto the outer surface of the flexible belt has a uniform thickness. This enables the finished belt to be used as an organic photoreceptor in an xerographic imaging machine.
