摘要： A method and a system for controlling the moisture profile and/or moisture gradient of a paper web for production of at least SC quality paper in a paper machine comprising a calender (1) which has at least two roll stacks (21, 22; 31, 32), of which at least one has at least three rolls and of which at least another one has at least five rolls, and which calender is provided with a pre-moisturizer (7) placed before the calender, in which pre-moisturizer the web is moisturized to a desired pre-moisture content M1, and with at least one intermediate moisturizer (3) arranged between two roll stacks to a desired intermediate moisture content M2 before the last roll stack (31, 32), in which the web is dried to a desired final moisture value M3. In accordance with the invention, for continuously controlling and optimizing the moisture profile and/or moisture gradient of the web, the premoisturizing W1 of the web is controlled by a control parameter of the premoisturizer (7) situated before the calender (1), which control parameter corresponds to the final moisture value M3 of the web.

摘要： The invention relates to a processing device and a method applying the same for processing a coated or uncoated fibrous web. The device comprises a belt (2) adapted to extend around a guiding element (3), at least one counter-element (5) being disposed outside said belt to provide a contact area with the belt, such that the belt (2) and the counter-element (5) establish therebetween a web processing zone for passing a web to be processed therethrough. The processing zone length is defined by means of the disposition of the belt's (2) guiding element (3) and/or by means of the design of the counter-elements (5). The contact pressure applied to a web in the processing zone is adapted to be adjustable within the range of about 0.01 MPa to about 200 MPa. The invention further relates to a method for switching paper, board or tissue from one grade to another, where the adjustment of the temperature applied to the web is essentially performed only by means of the adjustment of the metal belt temperature, a mechanism for the adjustment of a belt-tension inflicted compression force, a device for controlling and profiling the lateral tension and/or temperature of the belt, a processing device where the metal belt loop os adpated to run in an enclosed or isolated space and a processing device where the position of the belt in lateral direction is adjusted.

摘要： Method and apparatus for producing calendered paper by means of an off-line calender. A paper web (W) moistened in a paper machine and reeled on a machine arranged multinip calender (1), whose roll assembly is formed of a first set of rolls (2) and a second set of rolls (3) in the travel direction of the paper web (W). At least one surface (S1, S2) of the paper web (W) is moistened with at least one pre-moisturizer (8, 8’, 8’’), whereafter the paper web (W) is guided to the first calender nip (N1) of the first set of rolls (2) and one surface (S1, S2) of the paper web is moistened with at least one intermediate moisturizer (9, 9’), whereafter the paper web (W) is guided to the first calender nip (N1’) of the second set of rolls (3), wherein a paper web (W) having roughness of 1,0 -1, 1 µm and/or gloss of 54-57 % or 56-60 % is produced as a result of calendering.

摘要： A method for producing calendered paper by an on-line manufacturing system comprising at least a paper machine and a multi-nip calender. The method comprises following steps; removing water from a formed paper web by pressing, drying the pressed paper web by at least one dryer, calendering the dried web by the multi-nip calender, measuring a cross machine moisture profile or a variable relative thereto, and altering the moisture of the web so that the moisture profile of the web in cross direction is even when the web enters the first nip of the calender.
