摘要

The method involves forming and pouring a curtain (5) of coating fluids (1-4) including an organic liquid or a mixture of coating material and organic liquid, from a nozzle (11) to the surface of a web material (10) conveyed at right angles to the curtain. The organic liquid has a surface tension of at most 40 mN/M. A fluid coating (6) is solidified on the surface of the web material.
