The invention relates to a method for the production of single- or multiple- coated paper and/or cardboard, with the exception of photographic paper and self-adhesive labelling paper, which are particularly suitable for printing, packaging and lettering. The substrate such as, for example, raw paper or cardboard, is singly- or multiply-coated with a free-falling liquid curtain, whereby the coating liquid particularly has an elongational viscosity between 1 and 1000 Pa.s at a Hencky strain rate between 1 and 15.
L'invention concerne un procédé pour fabriquer du papier et/ou du carton revêtu d'une ou de plusieurs couches, hormis le papier photographique et le papier d'étiquetage autocollant, ce papier et ce carton étant particulièrement adaptés à l'impression, à l'emballage et à l'étiquetage. Le support, tel que du papier support ou du carton, est revêtu d'une ou de plusieurs couches par un processus de chute libre de liquide, le liquide de revêtement présentant une viscosité d'extension allant de 1 à 1000 Pa.s pour une déformation selon Hencky variant entre 1 et 15.
