  • Publication number: 20080286475
    Abstract: The present invention discloses an apparatus for block type extrusion coating, and a process for forming block coating or grid-type coating on a substrate. The present invention uses a die set composed of an upper mold, a lower mold and a shim therebetween, which can be used to form a plurality of coated stripes. The present invention further uses several control valves, pumps and a controller to intermittently extrude a coating solution from the die set, so that the stripe coating is converted to a block coating. The block coated substrate can be rotated 90 degrees, followed by a stripe coating process to form a grid-type coating on the substrate.
