    摘要: A method and an arrangement for controlling evaporation and moisture in a multinip calender (10) when a continuous fibrous web (W) is calendered in calendering nips (1,_2,—3,—4,—5) placed one after the other before the fibrous web is wound on a reel-up/winder (9). With a view to making the net evaporation from and the final moisture content of the web (W) constant when the running situations in the calender (10) change, the web is passed in the calender from the outlet of at least one nip into an air-float chamber (20) of the turning airborne type.

    摘要: In the method for treating the surface of the web, liquid is added on the surface of a paper or paperboard web (W), possibly with other constituents. The absorbency of the surface of the paper or paperboard web is increased before liquid is brought on the surface of the web or simultaneously with bringing the liquid on the surface of the web. The method is used for wetting the surface of the web before calendering, or for coating the web in surface sizing or pigmenting. The absorbency of the surface is increased before bringing the liquid for example by means of a corona treatment, a flame treatment, an ozonization or by adding steam.

    摘要: In the method for manufacturing surface-treated printing paper, a paper web is first dried down to a target moisture of the surface treatment, and it is wetted again to the target moisture before the surface treatment. The rewetting to the target moisture is conducted on the web running to the surface treatment before a device effecting the surface treatment of the web, as seen in the travel direction of the web. Before re-wetting, the moisture profile of the web is adjusted in the drying section by wetting the web at a point which is located before the area of the heavy shrinkage (cd shrinkage area) in the travel direction of the web.

    摘要: A method and apparatus for manufacturing calendered paper in which the paper is calendered after drying. The paper is dried (D) sown to a moisture lower that the target moisture of calendering. The paper is run via wetting (1) to calendering, wherein at least one of the surface layer of the paper is wetted in the wetting in such that the moistening water is absorbed in the surface layer of the paper while at lest the central part remains substantially dry. From the paper wetted at least on one of its sides, gradient paper is manufactured by means of gradient calendering by restricting the paper-molding effect of the calender to the wetted surface layer in such a way that at least the paper is elastically restored substantially in its original state, whereafter the obtained gradient paper is reeled.
