Abstract
The invention relates to a method and an arrangement for double-sided coating of a thin printing paper web, for example a web containing recycled fibres. According to the invention the first side of the web 5 is coated in a first coating station 1, the first coating layer is dried at least partially by a drying arrangement 3, the second side of the web 5 is coated in a second coating station 2 after the first side has been dried, and the second coating layer is dried at least partially by a second drying arrangement 4. According to the invention both the first and the second coating layer are formed by spreading a requisite quantity of coating slip on a film roll 22, by means of which the coating slip is transferred in a roll nip N1 between a counter-roll 24 and the film roll 22 to the web 5. <IMAGE>
