ABSTRACT:
A die coating 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. A low surface energy covering is applied to the surface of the downstream bar adjacent to the sharp edge, and to the surface of the land, adjacent to its downstream edge. This presents a generally undulating surface. The low surface energy coverings need not extend completely to the edges of the downstream bar and the land.
