Abstract (en)
[origin: WO2018171959A1] The invention relates to a method for treating a fibrous web (1), in particular a paper or carton web in the end section of a machine for production thereof, which comprises a dryer section (2) for drying, a first smoothing device (3) for pre-smoothing, a coating device (9) for applying coating color, an additional smoothing device (4) and a rolling device (5) for winding the finished fibrous web (1), wherein the fibrous web (1) is guided through at least one cooling unit (6, 7, 10) having evaporation cooling between the drying section (2) and the rolling device (5). According to the invention, volume-protective smoothing and optimal rolling is enabled in that the fibrous web (1) is cooled by at least one cooling unit (6, 7, 10) in each case before the first (3) and between the first (3) and the additional smoothing device (4).
