Abstract:
An apparatus for applying a substantially uniform coating of a solution onto a substrate comprising:a substrate support for the substrate, the substrate support having a compressible layer at a nip area between a meyer rod and a substrate transport surface, the compressible layer having a compression stiffness (K);the meyer rod for metering the solution supplied at the nip area on the substrate, the meyer rod having an overall length (L.sub.rod), a total rod weight value (W.sub.rod), and a bow measurement (B);a weight for applying a substantially uniform force onto the meyer rod, the weight having a total weight value (W.sub.bar);a substrate transport surface for transporting the substrate through the nip thereby coating a layer of the solution onto the substrate, the layer having a width value (L); anda drying area for drying the layer of solution;such that the apparatus has a complaint coating number CCN of greater than about 1.4, the CCN being defined by formula (1): ##EQU4##
