Abstract (en)

[origin: WO2011151234A1] The invention relates to a method for producing a coated multilayer fibrous web, in particular a packaging paper or cardboard web. First, a material flow (S) is produced which is then successively fed to at least one headbox (1), at least one wire section (I) for forming a multilayer fibrous web (B), a pressing section (II), a drying section (III) with drying groups (8a, 8b), and subsequently a roll-up device. The method is characterized in that the fibrous web (B) produced in a multilayer manner is precalendered with a belt calender (13). Afterwards, the top layer of the fibrous web (B) is coated with a white coating layer that contains a white pigment using a curtain application unit (14.1) and then dried.
