Abstract
Flexible edge sealing membranes cooperate with the heating surface of a vacuum preheater and a web moving over the surface (1) to minimize air loss in the portions of the heating surface not covered by the web, (2) to prevent differential heating of the edges of the web induced by unrestricted air flow, and (3) to provide reduced friction contact with the edge portions of the web.
