ABSTRACT:
Composite coatings are provided having a variable thickness and a coloration gradient in the cross-web direction using shims to direct flow in a premetered extrusion extrusion process and an edge band is used to provide stability to the bead. Further stability is provided by a vacuum gradient matched to the specific shim design used. The composite coatings are useful in preparing laminated structures such as automobile windshields with a gradient band.
