ABSTRACT:
A method and apparatus for two-side coating of a light base weight printing paper web containing mechanical pulp or recycled fiber. The first side of a web (5) is coated in a first coating station (1), the coating applied to the first side is dried at least partially in a first dryer unit (3). The second side of the web (5) is coated subsequent to the drying of the first side in a second coating station (2), and the coating applied to the second side is dried at least partially in a second dryer unit (4). Both coatings are formed by applying a required amount of coating mix onto the perimeter of respective soft film-coating rolls (22) and subsequently transferring the coat film to the web (5) in a nip (N.sub.1) formed between a respective backing roll (24) and the respective soft film-coating roll (22).
