ABSTRACT:
A die coating method and apparatus includes a die having an upstream bar with an upstream lip and a downstream bar with a downstream lip. The upstream lip is formed as a land and the downstream lip is formed as a sharp edge. The shape of the land conforms to the shape of the surface being coated. Changing at least one of the slot height, the overbite, and the convergence can improve coating performance. A replaceable, flexible strip can be used above the coating slot to facilitate replacement of a damaged overbite edge. The strip can be held in position by vacuum applied through the downstream bar.
