  • the invention relates to a method in a paper or board machine according to the preamble of claim 1.
  • the invention also relates to a device in a paper or board machine according to the preamble of claim 12.
  • twin- wire draw and/or single-wire draw is/are employed, h twin-wire draw, the groups of drying cylinders comprise two wires which press the web, one from above and the other one from below, against the heated cylinder surfaces. Between the rows of drying cylinders, which are usually horizontal rows, the web has free and unsupported draws which are susceptible to fluttering, which may cause web breaks, in particular as the web is still relatively moist and, therefore, has a low strength.
  • each group of drying cylinders comprises only one drying wire on whose support the web runs through the entire group so that the drying wire presses the web against the heated cylinder surfaces of the drying cylinders and the web remains at the side of the outside curve of the reversing cylinders or rolls situated between the drying cylinders.
  • the drying cylinders are arranged outside the wire loop, and the reversing cylinders or rolls are arranged inside the loop.
  • the rum ability of a paper machine is, of course, also affected by the dryer section, whose length with the prior art multi- cylinder dryers would, at high speeds, also become very long. If it is imagined that a present-day multi-cylinder dryer were used at a web speed of 40 m/s, it would include about 40 - 80 drying cylinders, and its length in the machine direction would be about 180 m. In such a case, the dryer would comprise several wire groups and a corresponding number of draws over the group gaps.
  • the dryer sections of paper machines known today are formed of dozens of drying cylinders and reversing rolls or reversing cylinders associated with them. In a modern high-speed newsprint machine there are in total about 60 - 80 such rolls and cylinders.
  • the paper web may be constricted unevenly, and high differences in tension applied to the web may cause problems in achievement of a sufficiently uniform quality, in particular in relation to the cross- direction profile of the paper.
  • the method according to the invention is mainly characterized in that which is stated in the characterizing part of claim 1.
  • the device in a paper or board machine according to the invention is mainly characterized in that which is stated in the characterizing part of claim 12.

  • the web is transferred from a press section onto the large impingement roll as a supported draw and as of full width.
  • a vacuum is provided through a perforated roll shell to the surface of the roll, and the web is transferred by means of said vacuum onto the surface of a transfer fabric on the surface of the roll.
  • the web is transferred from the transfer fabric onto the fabric of the impingement roll (large vacuum roll) by means of the vacuum of the large vacuum roll.
  • the impingement or vacuum roll represents prior art known in itself as applied in the invention to a larger size.
  • the roll can thus be of the type known under the applicant's trademark NacRoll, in which the vacuum prevailing inside the roll acts to the same extent over the entire length of the circumference of the roll, and the interior of the roll has not been divided into separate chambers. It is also possible to use a conventional suction roll type, in which connection one or more boxes are arranged in the interior of the roll to divide the roll in the circumferential direction into chambers, sectors, in which vacuums of different magnitude can be used.
  • the diameter of the roll is over 2.5 m, even over 10 m, most appropriately 3 - 6 m. There may be one or more impingement drying groups one after the other.
  • the diameter of the roll is typically over 10 m. When several rolls are used in succession, their diameter is typically 3 - 6 m.
  • the web is dried on the large roll by the impingement technique, and a first measuring beam is located after the impingement proper, said measuring beam measuring moisture, basis weight, ash and the like from one side while the paper is against a wire. After the measuring beam, these is an impingement portion in which the moisture profile of the web is corrected and this is followed by correction of curl by moisturizing.

  • the next step is to treat the surface of the paper, hi the arrangement in accordance with the invention, the web is passed from the wire of the large impingement roll by means of a suction roll to a calender, which is formed by, for example, a smooth heated roll and a belt roll placed against it.

  • the arrangement in accordance with the invention provides a fully closed draw all the way to the calender, even through the paper machine, and full-width threading can be accomplished through the dryer section, even as far as the calender and the reel. Since the web is supported from the press section to impingement drying and advantageously further to the calender, the solids content of the paper need not be raised in the press section for runnability, but, instead, it is possible to run the desired solids content. Moreover, quality values can be selected as the determining factors in treatment once runnability problems have been solved.
  • W en the arrangement in accordance with the invention is applied and when a measurement device is advantageously placed in connection with the impingement roll, it is also possible to utilize a web possibly of poor quality produced in the starting stage, which web can be run and the values can be adjusted to a correct level.
  • impingement drying in accordance with the invention, steam is not needed, but impingement is most appropriately accomplished with gas, for example, natural gas.
  • the invention also allows a draw difference according to the desired quality to be used because runnability is not a decisive factor.
  • the moisture profile also need not be as precise when coming from the press section as in the prior art arrangements because, when using impingement, the web can be made dry at one go, in which connection no transfers are needed from one cylinder to the next, during which transfer the web having an uneven moisture profile adheres unevenly to the cylinder and causes runnability problems.

Pikulik 1.1 Approach Flow System The forming process is preceded by an approach flow system that receives the aqueous fiber suspension, or stock, and prepares it for the forming process. Fibres are produced using kraft process or other pulping/bleaching processes (see Bleaching of wood pulps) and the proportions of fibers from different sources are blended here. Drained water from the forming process, known as whitewater, contains useful fibrous material and is continuously recycled back into the stock. Screens and centrifugal cleaners in the approach flow system remove oversize and heavy contaminants from the pulp. Additives such as minerals, pigments and dyes are introduced to make particular grades of paper and paper board. Air bubbles may be removed from the pulp suspension. The mass concentration, or consistency, of the suspension is kept low to prevent fibre flocculation prior to forming and is usually adjusted to a value in the range of 0.5 to 1.5%.
