Inserts for stripe coating

A coating insert used within a coating assembly for defining at least one edge of coating fluid as it is applied to a substrate moving past the coating assembly is disclosed. The coating assembly includes a trough having first and second transverse ends. At least one coating insert is inserted within the trough to define an edge of coated fluid on a substrate. The coating insert, having one or two edge-defining surfaces, is positioned within the trough. The first end of the edge-defining surface is closer to the adjacent transverse end of the trough than the second end of the edge-defining surface. The top face of the coating insert may also include a second edge-defining surface having first and second ends that may define another edge of coated fluid on a substrate.
