ABSTRACT:
A method and an apparatus for direct or indirect one-sided or double-sided application of a liquid or pasty coating medium onto a spliced traveling material web, notably of paper or cardboard, includes at least one applicator applying the coating medium at a predetermined point of coating application onto the material web. At least one coating suspension system briefly suspends the application of the coating medium at the point of coating application or at a point of suspension located, based on the direction of travel of the material web, ahead of the point of coating application. The suspension of the application of coating medium occurs while or before the material web splice passes the point of coating application.
