ABSTRACT:
A coating process for coating traveling webs comprises applying a first coating layer of a pigment substance on a portion of the shell surface of a rotatable roll not covered by the material web, and pressing the pigment substance onto the web in a press gap, thereby impregnating the web. This makes it possible to apply with maximum uniformity and without web breaks and wrinkles a second coating layer of a pigment substance immediately successive to the application of the first layer, while the first layer is still moist.
