  • Patent number: 5389150
    Abstract: The present invention describes slot inserts for use in a coating hopper having at least one metering slot. The slot inserts allow widthwise adjustment of the coating width. The slot inserts push fit into the metering slot and are held by friction between the walls of the metering slot. In one aspect of the invention, the inserts have different widthwise dimensions at each end allowing control over the edges. For dual cavity hoppers, the slot inserts can be shaped so as to prevent stagnant regions within the hopper cavities.
