    摘要： A method in a dryer section of a paper or board machine for controlling curl of paper, in which steam treatment and/or moistening of the paper web is/are employed. The operations carried out in order to control the curl of the paper web are carried out in a number of stages when the web temperature is, during at least one stage, lower than 85.degree. C., preferably lower than 75.degree. C., and when the dry solids content of the web is in the range of K1-K2, wherein K1 is the ultimate dry solids content of the web -7% and K2 is the ultimate dry solids content +3%.

    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： The invention concerns a dryer-section concept of a paper/board machine and a method in the drying of a paper/board web (W). The dryer section comprises a number of drying cylinder groups (R.sub.I . . . R.sub.N), which comprise a single-wire draw, on whose support the web (W) is guided so that it meanders as loop-shaped from a drying cylinder onto a suction cylinder. The web (W)/the wire (H) is guided so that the web is placed against the face of the drying cylinder and the wire is placed outside. In the dryer-section concept, the web (W) is passed from one drying cylinder group (R.sub.I) into the next dryer group (R.sub.II) and further. According to the invention, at least some of the drying cylinders (K'.sub.1, K'.sub.2, K'.sub.3) include impingement units (100, 101, 102) or equivalent in connection with them, through which units a heated medium, preferably air or steam, is passed through the wire into connection with the web (W) so as to produce a two-sided drying effect and to increase the drying capacity.

    摘要： The invention concerns a method and a device in the dryer section of a paper/board machine. In the dryer section a normal single-wire draw is applied at least partly, in which method the web (W) is passed through the dryer group on support of a drying wire (H). The drying wire (H) presses the web (W) on the drying cylinders (Kn, Kn+1 . . . ) against the heated cylinder faces, and on the reversing cylinders or rolls (Sn, Sn+1 . . . ) between the drying cylinders (10) the web (W) remains at the side of the outside curve. There is one integrated device, through which a support suction and/or blowing is produced in order to improve the runability of the web (W) and to keep the web (W) in contact with the face of the wire, and through which same device, additionally, impingement blowing is produced in order to dry the web (W) and/or to control its tendency of curling.
