    摘要： The invention relates to a processing device and a method of 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 there between a web processing zone for passing a web to be processed there through. The processing zone length is defined by means of the disposition/adjustment of the belt’s 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 70 MPa. The invention further relates to a method for drying a paper/board web by pressing it in a processing device provided on both sides of the web.

    摘要： The present invention relates to a method for calendering a moving web (1) of paper or board. The web (1) is passed to a calender (2) and calendered therein. At least one quality of the calendered web (1) is measured at a first measurement point (3) adapted at a location downstream from the calender (2). Additionally, at least one quality of the web (1) entering the calender (2) is measured at a second measurement point (4) adapted at a location between the calender (2) and the preceding section of the line. A control variable (6) affecting the calendering effect on the calender (2) is controlled by a feedback control scheme based on the measurement result obtained from said first measurement point (3) and a control variable (9) affecting the processability of the web (1) to be calendered is controlled by a feedback control scheme based on the measurement result obtained from said second measurement point (4).

    摘要： The invention relates to a method for monitoring and storing the properties of various components (1) of a paper/board or pulp and finishing/converting machine (20) and the changes taking place in them and/or the ambient conditions and the changes taking place in them, and for transmitting this data to the control unit (10) of the paper/board or pulp or finishing/converting machine (20) and/or to a separate data processing system (4). In the component (1) is arranged a memory unit (2) accompanying it, in which can be written or which can be read electrically, by magnetisation or optically, in which memory unit are stored at least those properties (A) of the component (1) which affect the control values of a paper/board or pulp or finishing/converting machine (20). The method and device also comprise data transmission means (9b, 3b) for transmitting the data stored in the memory unit (2) to the control unit (10) of a paper/board or pulp or finishing/converting machine (20) and/or a separate data processing system (4).
