ABSTRACT:
A plurality of articles such as sheets or lenses are simultaneously and uniformly coated by first placing them in vertical spaced relationship with respect to each other within a tank having a quantity of fluid coating material therein. The coating material flows across the surfaces to be coated. Thereafter, the sheets are lifted out of the tank into an elongated chamber above the tank in which they are spun about their vertical axes. Excess coating material is thus driven off the surfaces to be coated. Means to recover, clean, replenish and remove bubbles from the coating material are disclosed.
