Coating device and method using pick-and-place devices having equal or substantially equal periods

摘要: A sufficient number of pick-and-place devices (e.g., rolls) whose periods contact with a substrate are equal or substantially to one another used form continuous void-free uniform coatings despite the occurrence unintended intended coating caliper surges, depressions voids. The wetted surfaces and re-contact at positions on that different from another. Extremely extremely thin can be obtained very high rates speed. also facilitate drying reduce sensitivity ovens surges. Equipment containing is simple construct, set up operate, easily adjusted alter thickness compensate for variations.
