摘要： A fiber-web machine dryer section has a drying group with single-wire draw so the drying wire (F) presses the web (W) against heated cylinder surfaces with the web (W) at the side of the outside curve of reversing cylinders (11) situated between drying cylinders (10, 12). A pocket space (T) is formed between two adjacent drying cylinders (10) and a reversing cylinder (11) situated between them, and the drying wire (F). A negative pressure component (20) placed in the pocket space (T) creates a pressure difference over the drying wire (F) and the web (W) for attaching the web (W) to the drying wire (F) so the cross-direction shrinkage of the web (W) is controllable. The wire tension (F) is maintained at a level help control cross-direction shrinkage of the web. The pocket space (T) is sealed by sealing members (25, 26) to maintain negative pressure in the pocket space.

摘要： The invention relates to a multiroll calender for calendering a fiber web, particularly a paper or board web (W), which multiroll calender comprises at least two sets of calender rolls (10, 20) and a frame (40), the set comprising at least two calender rolls, in between of which calender rolls a calendering nip is formed, and at least one fly roll, in which at least one calender roll is attached by a pivotable lever (45) by a joint (50) to the calender frame (40). At least one fly roll (15, 25) of the multiroll calender is an inner fly roll (14, 24) and that at least one inner fly roll (15, 25) is attached at the center of the joint (50) of the lever (45), advantageously fixedly, such that the distance travelled by the web (W) between the nips of the calender does not cause web tension changes when the set of rolls is moved.

摘要： A refiner (10, 11) for refining fibrous material has a first refining surface (1') and a second refining surface (2') arranged opposite to one another and mobile in relation to one another. The refining surfaces have refining surface portions (15, 27) feeding material to be refined and/or discharging refined material as well as refining surface portions (16) grinding the material to be refined, on the upper surface of which there are blade bars (17) and between them blade grooves (18). In the refining surface (1', 2') of the refiner (10, 11) the cross-sectional area (A) of at least some blade grooves (18) is arranged to decrease from one blade groove (18) to the next from the direction of the feed edge (13) to the direction of the discharge edge (14) of the refining surface (1', 2').
