Abstract
Solvent which is contained in coating material to be applied to a running web is recovered in a chamber which is sealed from the atmosphere and wherein the solvent-containing coating material is first applied to one or more endless belt conveyors which transport the respective layers to discrete transfer stations for application to the running web. Streams of an inert gaseous fluid are circulated through the chamber to withdraw the solvent and to convey it into a condenser wherein the solvent is recovered from the gaseous fluid. The inert gaseous fluid is heated to promote the expulsion of solvent from the coating material on the conveyor or conveyors. The web can be provided with a base coat upstream of the first transfer station so that the layers of coating material are applied over the base coat. The latter is dried upstream of the transfer stations.
