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 concerns a method in the dryer section of a paper or board machine for control of the curl of paper, in which method steam treatment and/or moistening of the paper web (W) is/are employed. In the method, the operations carried out in view of controlling the curl of the paper web (W) are carried out in a number of stages and/or when the web (W) temperature is lower than 85 DEG C, preferably lower than 75 DEG C, and/or when the dry solids content of the web (W) is in the range of K1...K2, wherein K1 = ultimate dry solids content - 7 % and K2 = ultimate dry solids content + 3 %. Further, the invention concerns a paper or board machine, which comprises at least a headbox, a former, a press, and a dryer section, in which steam boxes or moistening devices are employed for control of the curl. There are at least two of said curl regulation devices in view of achieving a regulation of the curl in a number of stages, and/or said curl regulation devices have been fitted to operate in an area in which the web temperature is lower than 85 DEG C, preferably lower than 75 DEG C, and/or the dry solids content of the web is in a range of K1...K2, wherein K1 = ultimate dry solids content - 7 % and K2 = 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： A method and an apparatus for web threading in a drying section of a paper machine or the like. A leader (24) and a so called run-down strip are formed by cutting in the web coming to the drying cylinder in the drying section. An underpressure box (18) is arranged at the opening gap between the drying cylinder (14) and the drying wire, on that side of the wire which is away from the web, whereby this box can direct against the web an underpressure which is controllable in the machine's cross direction. The underpressure box creates an underpressure region (34') between the leader and the underpressure box, the region having an underpressure p1 at the detachment point, i.e. in the area where the wire is detached from said drying cylinder (14), which underpressure is sufficient to detach the leader from said drying cylinder. A protection zone is created between the underpressure region created at the leader and the run-down strip, which protection zone has a barrier (46) in order to maintain the underpressure p1 in the underpressure region.

摘要： The invention relates to a method for measuring and regulating curl in a paper or board web, in which method the curl of the paper or board web (W) is regulated. In the method, in connection with the manufacture of the paper or board web (W), the paper or board web is slit or cut, the rising/lowering (H) of the edges of a slit/cut gap (C) formed at the slitting/cutting point or the width (L) of the gap is measured by means of a measurement device (21A; 21B; 21C), and the curl of the paper or board web (W) is regulated based on the result of measurement. The invention also relates to a paper or board machine line which comprises sections for the manufacture of a paper or board web (W), which paper or board machine line comprises a means or means for regulating curl in the web (W). The paper or board machine line comprises means for slitting or cutting the paper or board web and for measuring the rising/lowering (H) of the edges of a slit/cut gap (C) formed at the slitting/cutting point or the width (L) of the slit/cut gap (C) in connection with the manufacture of the web (W) in order to regulate the curl of the web (W) based on the result of measurement.
