摘要： A method and device for drying a coated web. The coated web is first conveyed through a web heating unit (10, 32, 40), in which the temperature of the coated web is raised, typically to drying temperature, by directing jets of heating air at the coated web, the humidity a1 of the said heating air jets being higher than the humidity a2 of the drying air jets. After this the coated web is conveyed through at least one air dryer (34, 36, 38; 42, 44, 46), in which drying air jets are directed at the coated web for drying the coated web.

摘要： A paper web (W) is dried in a forward dryer section (D) of a paper machine in downward open drying groups (G1 . . . G6) that apply single-wire draw. Then, in a finishing section the web (W) is surface-sized in a surface-sizing unit (20) and dried mainly by contact-free drying: partly by airbone web-dryers (31, 32, 34, 36) or by impingement drying. The power of the airbone web-drying/impingement drying is regulated on both sides of the web (W) such that the tendency of curling created in the web (W) in the forward dryer section (D) can be controlled.

摘要： A web (16) running from an opening nip (K1) between a cylinder (10) and a supporting fabric (18) toward a roll (14), is supported by a negative pressure created by a blow box (30). In an intensified negative pressure region (34′), i.e. close to the disengaging point (40) between the supporting fabric and the cylinder, the pressure is greater than at a distance from this disengaging point. The negative pressure is controlled according to parameters which act on the runability of the web and which can be varied, such as web velocity, web solid contents, pulp composition, paper or paper board quality, web grammage, a characteristic of the web, such as porosity, traction acting in the web, or web tension, cylinder temperature, and/or the running situation, such as a web break, a threading situation, or a normal run, so the desired runability is maintained between the cylinder and the roll.

摘要： The invention concerns an equipment and a method in the transfer of a paper/board web in a paper or board machine. In an embodiment of the invention, the dryer section comprises at least one group of drying cylinders in which, instead of a conventional wire draw, a transfer belt (H100) is employed, to which the web (W) is affixed by effect of adhesion and which transfer belt is passed over drying cylinders (K1, K2, . . . ) and reversing rolls (E1, E2, . . . ) and further in said group (RI) of drying cylinders in the dryer section. The invention also concerns a method in the transfer of the web (W) in the dryer section (K) of a paper/board machine. In an embodiment of the invention, the web (W) is passed, while meandering in loop shape and while adhering to the face of the transfer belt (H100), from a drying cylinder (K1) in the group (RI) of drying cylinders in the dryer section (K) onto a reversing roll (E1) and further from the reversing roll onto the next drying cylinder (K2) and further in the group (RI) of drying cylinders.

摘要： A high speed dryer section has single-wire draw drying groups (R1, RN). A paper or board web (W) is supported by a wire (F) as it meanders over drying cylinders (20) in an upper row and reversing cylinders/rolls (21) in a lower row. A first cylinder drying group (R1) has at least five drying cylinders. In the first cylinder drying group (R1) a runnability component (30) is placed in a pocket space defined by every two successive drying cylinders (20) and the reversing roll (21) between them and by the drying wire (F) for applying a high under-pressure of 1000-8000 Pa to an area (50Y) in which the web (W) separates from the drying cylinder (20), and by which runnability component (30) a lower under-pressure of 100-500 Pa is produced in at least part of the rest of the pocket space (T).

摘要： The invention relates to a sealing arrangement (7) against a moving fabric (4b) in a paper machine or the like. The sealing arrangement includes a stiff sealing element (9) placed on the fabric's (4b) side on the entire width in connection with a paper sheet (4a) supported by the fabric (4b). The sealing element has been arranged on a support so that the location of the sealing element with respect to the fabric (4b) can be adjusted nearer to or, correspondingly, further from the fabric. As a sealing element there is at least a single-chambered labyrinth sealing (19).
