ABSTRACT OF THE DISCLOSURE A moving essentially non-porous web is positioned above and in close proximity to the upper surface of a narrow very shallow pool of coating solution. A coating meniscus extends directly from the upper surface to the web to transfer coating solution from the pool to the web. Stagnation of solution in the pool is eliminated by feeding solution to the pool at the center and bottom thereof, and removing excess solution through ports at the top surface of the pool at each end thereof.
