ABSTRACT:
Webs coated with several layers, of which the lowermost or uppermost layer contains an instant hardener, may be produced in a single operation by curtain coating using a V-coater when the hardening layer is guided at the negatively inclined sliding surface of the V-coater while the other layers are guided at the opposite sliding surface of the V-coater and the hardening layer is combined with the remaining layers at coating edge to form a layer packet which is applied as a free-falling curtain to the web to be coated.
