Abstract

Process and device for drying a moving web. The process includes vaporizing moisture in the web, creating a blanket of compressed air along a first surface of the web, and the blanket of compressed air directing the vaporized moisture in a direction from the first surface toward a second surface of the web that faces away from said blanket of compressed air. The device includes an air-tight guide element positioned adjacent to the moving web and positioned to create a blanket of compressed air between the moving web and the air-tight guide element
