Abstract
A coating die having a shut-off bar positioned to stop the flow of coating material within the flow channel of the die when the shut-off bar is in the closed position. In the closed position, the shut-off bar extends across the material flow channel, blocking flow of coating material therethrough. The shut-off bar moves essentially orthogonal to the direction of material flow. In some embodiments, the flow channel includes a shoulder against which the shut-off bar physically seals, the seal being essentially transverse or orthogonal to the direction of the material flow channel. Coating dies having a shut-off bar are particularly suited for patch coating applications.
