Definitions

  • the invention relates to a method for manufacturing and further processing of paper.
  • the papermaking process uses a variety of one or more subsequent further processing processes with significant characteristics, mostly mechanical and technological features, of the paper. These change during production also within a particular paper type and across the web width more or less strong.
  • the respective further processing process it can is, for example, a printing process, a formatting process, act in particular cutting process, or the like.
  • the web shrinkage is not just from the latitude position, but also of the fiber properties and the draws in the paper machine dependent.
  • FIG. 1 Two possible transverse shrinkage curves are shown in FIG. 1. there is the shrinkage in the left area on the driver's side and in the right area of the shrinkage reproduced on the drive side of the paper machine.
  • the shrinkage In the central area, the shrinkage is usually constant, while the paper increasing towards the two edges shrinking. While according to the upper transverse shrinkage curve shown in Figure 1 the shrinkage in the central area is constant, this becomes Consistency in the central area was not achieved in some cases (cf. the lower one Cross shrinkage curve of Figure 1). Also through different raw material compositions and production process can be a different one Shrinkage behavior arise.
  • the curve shape can be in the edge area be very different, although they are always non-linear in this area is.
  • the paper produced in the paper machine is then processed on so-called Drums rolled up.
  • the resulting full drum usually have a width of 2 m to over 10 m and one Diameter from currently up to almost 4 m, the tendency is increasing.
  • the paper for newspaper printing is preferably on Roll cutting machines processed into smaller rolls. common are widths from 0.3 m to 1.4 m, sometimes even up to 2.8 m, and Diameters from 0.9 m to 1.5 m, with the trend increasing here too is. Papers for cardboard packaging are mostly used on cross cutting machines cut into individual sheets.
  • Paper that does not shrink constantly during its manufacture brings problems with increasing roll width. That's not the reason constant shrinkage in the manufacture of the paper also a non-constant Elongation when printing. Registration problems can only be limited compensated for example by the measures described above become.
  • the extent of printing can range from a few 1/10 mm up to 3 mm or more, depending on the paper and the position being viewed the role.
  • a width or transverse expansion of the Paper web determined.
  • the determined width or transverse expansion is for a Drive control used by at least one of the draw rollers to maintain a constant width or transverse extension of the paper web.
  • the Values used for the control are here in the range of Printer measured.
  • the aim of the invention is to provide an improved method of the aforementioned Way of creating, in particular the ones mentioned above Disadvantages are eliminated.
  • This object is achieved according to the invention in that for optimization at least one further processing process in papermaking determined information about the respective paper to the respective Subsequent processing process transmitted and taken into account in this become.
  • the respective further processing process can be, for example a printing process, a formatting process, especially one Act cutting process, and / or the like. Basically it is too possible in several further processing processes already at the Paper production information to be taken into account.
  • the relevant information for example on the type of filler, amount of filler, type of fiber, amount of fiber, obtain chemical additives and / or the like.
  • Procedures are considered as information obtained in papermaking information on at least one property and / or Longitudinal compositional profile for the respective further processing process transmitted and taken into account in this. there can, for example, transmit "running meter” -related information and be taken into account.
  • Procedures are considered as information obtained in papermaking information about at least one longitudinal and at least one cross-section of the data relating to the paper web to the the respective further processing process transmitted and taken into account in this.
  • the transmission of a corresponding one Information grid or network conceivable.
  • the information obtained in papermaking is preferred after a roll cutting process using data carriers of each Assigned role.
  • the roll cutting process can be particularly in the paper mill occur.
  • finishing process is a printing process becomes Optimization of this printing process the one created during paper production Shrinkage of the respective paper when printing accordingly is also taken into account.
  • the basic model for the prediction of the expansion can arbitrarily such boundary condition parameters are expanded.
  • the shrinking properties of the paper can then be used for printing through suitable measures, both the fan-out and web tension differences be compensated in the transverse direction of the roll.
  • the transverse shrinkage that occurs when producing a paper web is known. For example, with a Voith Sulzer ModuleJet® Headbox and Profilmatic M® software package Paper machines calculated the cross-shrink curve.
  • the existing data structure can then in particular individual shrink values can be added.
  • the shrink curve can e.g. through a straight line or a segment of a circle approximated and a deflection and one Marginal offset value can be described.
  • a so-called spreader roller is also used.
  • the paper can wrap around the roller at an obtuse angle. Shows the spreader roller bow towards the tip this obtuse angle, the web train becomes in the middle of the paper web increased to the maximum as it descends towards the edges of the paper web. Does the arc point in the direction of one leg of the obtuse angle or is achieved by swiveling the spreader roller accordingly, that the paper only touches the roller, the web tension distribution remains Paper web largely unchanged. By swiveling the bow Any intermediate values can also exist between these two positions this train train influence can be achieved.
  • Another way of eliminating uneven paper stretch consists of targeted humidification.
  • one of the previously known methods for metered application on paper web such they e.g. can be used in coating machines or coaters
  • the Printing press specifically apply moisture to the paper, so that e.g. Paper areas with smaller shrinkage values moistened more are considered paper areas with larger shrinkage values, which again an even expansion of the paper is achieved.
  • the relevant shrinkage characteristics can be used for packaging, for example of paper in the paper mill noted on the roll label become. It can also in the paper web itself during the production process the paper mill with relevant data. This could be in the The simplest case is that a high-speed printer is used in the edge area Information in the visible wavelength range printed, which are scanned again at the latest when printing become. In principle, any other writing method is also possible conceivable to generate the information in the invisible area and thus have no negative impact on print quality. This Information could not only be in the marginal area of the web, but in each case can also be applied to the edge of a roll.
  • border papers are used, which have been compared so far were classified as inferior to paper from the middle range.
  • the following shrinkage control is conceivable, for example: in reel production are in many cases already the roles or. Arc widths known. Paper shrinkage can now, for example adjusted and / or regulated so that the shrinkage of the Paper of the roll provided for example on the left in the direction of paper travel decreases linearly towards the center of the paper machine, with the neighboring ones Rolling is then constant and finally in the direction of paper travel For example, the role provided on the right increases linearly again.
  • For regulation of the shrinkage can, for example, air on the underside of the felt be blown in. This creates a kind of air cushion between the felt and the paper in the area of which the paper shrinks linearly. The air can, depending on the influence of the moisture profile, directly or by blowing of a drying cylinder.
  • the flow of the Dry felt can be set, for example, using air pressure. Ideally should have such an air cushion in the area of the edge roller width Exception of the outermost edge of the web.
  • An essential idea of the invention is therefore that Data of the paper properties of a paper roll to the printer for optimization of the printing process.
  • the invention is not only on paper including cardboard, but also basically also applicable to other materials to be printed.
  • the processing is one Printing process
  • the invention can optimize the printing process the shrinkage of the respective in the paper production Paper are taken into account accordingly when printing.
  • the shrinkage curve can be simplified e.g. approximated by a straight line 10 or a circular segment 12 ' and by a deflection and an edge offset value 14 and 16 respectively are described (see FIG. 2).
  • FIG 2 is a schematic representation of the shrink profile SP of a reel, which after cutting into roll formats for example, two straight lines 10 and result in two edge sections 12.
  • Shrink profile can thus be approximated by a respective straight line 10.
  • the two edge sections 12 are each separated by a circular segment 12 ' approximate and with a deflection and an edge offset value 14 and 16 respectively.
  • Such an approximation is in the lower part of FIG shown for the left edge portion 12 of the shrink curve.
  • a so-called spreader roller 18 (see FIG. 3) can be used.
  • Such an arcuate Originally cylindrical roller is currently used as a common used to generate an uneven web tension. there the paper 20 wraps around the spreader roller 18, in particular in obtuse angle.
  • the bow of the spreader roller 18 preferably points in the direction of the tip thereof obtuse angle, so the web tension is in the middle of the paper web increased to the maximum as it falls towards the edges of the paper. Shows the arc in the direction of a leg of this angle or will achieved by swiveling the spreader roller that the paper 20th this spreader roller 18 only affects, the web tension distribution remains Paper web 20 largely unchanged. By swiveling the bow Any intermediate values can also exist between these two positions this train train influence can be achieved.
  • the spreader roller 18 is perpendicular to the paper running direction L on one side in the paper web 20 placed that thereby the described with reference to Figure 2 Edge offset 16 is compensated. Then the spreader roller pivoted so far that a corresponding immersion depth of the arch the deflection 14 described in Figure 2 is compensated. On In this way, a largely constant web tension over the paper web can be achieved 20 can be achieved.
