    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： 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 concerns a calender provided with an extended nip for calendering of a paper or board web. The calender comprises at least one calendering nip (N), which is formed between a heatable hard roll (1) and a calendering belt (10) which has been formed as an endless loop and which is loaded against the heatable hard roll (1) by means of a backup roll (3) or a press shoe (24). The paper or board web (W) to be calendered is arranged to run through said calendering nip (N). According to the invention, in respect of at least a part of its thickness, the calendering belt (10) is made of a material of compressible volume. According to a second embodiment of the invention, the necessary resilience in the nip (N) is provided by means of a separate support belt, which runs underneath the calendering belt in relation to the web (W).
