ABSTRACT:
A running strip-shaped substrate of paper or thermoplastic material is provided with several layers of adhesive or other coating material at a transfer station where it comes in contact with discrete layers of coating material which are supplied by individual belt conveyors and are heated during travel with the respective conveyors to promote the expulsion of solvent which is gathered by individual streams of an inert gas flowing counter to the direction of travel of the layers with the conveyors. The layers are heated by the respective conveyors each of which is heated by a discrete heating device.
