미리계량한 압출 공정으로 흐름을 지정하는 쉼을 사용하여 웹 횡단 방향으로 가변 두께 및 착색 농담을 갖는 복합 피복재가 제공되고, 가장자리 밴드를 사용하여 비드에 안정성을 제공한다. 추가의 안정성은 사용된 특정 쉼 디자인과 어울리는 진공 구배에 의해 제공된다. 구배 밴드를 갖는 복합 피복재는 자동차 전면유리와 같은 적층된 구조물을 제조하는데 유용하다. 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.
