ABSTRACT:
Apparatus for applying one or more films of coating material to a running substrate of paper or the like has an endless belt which is trained over pulleys so that its upper reach advances toward a transfer station for coating material and its lower reach advances toward a station for the application of liquefied solvent-containing material. The underside of the lower reach of the belt is heated by a set of infrared heaters so that the liquefied coating material is applied to preheated portions of the belt. This promotes and contributes to predictability of expulsion of solvent from the film along the upper reach of the belt and ensures more predictable solidification of coating material ahead of the transfer station.
