Definitions

  • the invention relates to an application device, in particular a nozzle moistener for a paper machine a variety of machine-wide distributed nozzles for Spraying a passing paper web.
  • the invention relates to a paper machine for production of gravure and offset paper, with at least one Dryer section and a smoothing unit.
  • the Invention the use of a nozzle moistener Improving the paper properties of an offset paper.
  • the invention also relates to a method for Improving the surface of a paper for use as Offset printing paper.
  • Different printing processes are different Demands on the quality and properties of the produced Paper in order to achieve optimal print quality.
  • high-quality prints are printed in the Gravure printing or offset printing processes.
  • the printing ink is on the paper applied by first applying the paint in the wells a printing plate is stored, then when the Pressure plate over the passing paper from the paper to be taken over.
  • nozzle dampers are known in the prior art, with which water is sprayed onto a finished paper web, a desired, as even as possible around the paper web To give moisture profile. After this treatment the Paper web mostly passed through calenders, creating a as even and particularly smooth a surface as possible is achieved.
  • the nozzle humidifier is on the References EP 0 345 670 B1 and DE 38 19 761 C2.
  • Calender or smoothing unit is from the German, for example Publication DE 195 42 191 A1 known.
  • SC paper gravure paper
  • Paper machine for the production of rotogravure and offset paper with at least one dryer section and a smoothing unit to develop further in the area of Drying section at least one nozzle moistener is provided, that in the case of the production of gravure paper exclusively to even out the moisture cross profile the paper web is used and in the case of the manufacture of Offset paper only for the application of a Binder - preferably starch - is used.
  • the at least one nozzle moistener on both Sides of the paper web are provided.
  • an application device especially a nozzle moistener, for a paper machine a variety of machine-wide distributed nozzles for Spraying the passing paper web, suggested, at the at least one row with nozzles for the throughput of Water and / or a binder solution can be provided can.
  • This configuration makes it possible to focus on the special properties of binder solutions adjust so that the nozzles correspond to the different consistency, toughness and that Volume throughput can be adjusted.
  • Application device provides that for at least one Row of nozzles that penetrate the binder, medium can be used, the longitudinal profile and / or Cross profile of the applied mass of binder over the Regulate or control machine width. This will make it possible, either for a constant application layer to worry about in the manufacturing process, or even the cross section regulate or control the layer thickness via the web.
  • the means for regulating the control of the mass cross-section and / or the mass longitudinal profile of the applied binder can, for example, a variety of volume flow influencing valves, with each valve one Nozzle or a group of nozzles of the application device assigned.
  • Mass cross profile and / or the longitudinal mass profile of the applied binder by influencing that Concentration of the applied binder over the Machine width according to the requirements of one more or to regulate less intensive application of binders or to control.
  • a measuring device for the Mass cross profile necessary, for example can consist of a single measuring head over the Machine width is moved.
  • Measuring heads are used, which are fixed only one measure certain section or only over a certain one Area are movable in the cross machine direction and over move this area.
  • the application devices are also advantageously designed in such a way that the nozzles are designed for an average binder solution throughput which is based on an area application of 0.05 to 5 gr / m 2 of otro binder at a concentration of the binder solution of 2 to 30% by weight, preferably 5 up to 20% by weight, preferably 10 to 15% by weight, binder and a machine speed of 8 m / s to 50 m / s, preferably 10 m / s to 35 m / s.
  • the nozzles of the application device should have an average binder solution throughput of 0.03 l / min to 5 l / min, preferably 0.05 l / min to 3 l / min, preferably 0.06 l / min to 1 l / min , be designed.
  • the nozzle of the nozzle moistener Zone width - this is the distance from nozzle to nozzle in one machine-wide range - from 10 to 100 mm, preferably 20 up to 70 mm, preferably 25 to 50 mm.
  • nozzle humidifier to improve the To use paper properties of an offset printing paper, and binders on the passing web in the area of Apply dryer section. It is particularly cheap of course if the nozzle moistener is at least one of the previously mentioned features of a nozzle moistener according to the invention having.
  • the application of the Can be done with the help of a nozzle moistener it being especially for the application of the binder is favorable if the application of the binder by a spray with a droplet size of 20 to 250 ⁇ m, preferably 50 to 70 microns.
  • a spray with a droplet size of 20 to 250 ⁇ m, preferably 50 to 70 microns Alternatively or in There is also the possibility of applying the combination Binder, especially the nozzles of the Application device to design such that the Binder as a closed film on the paper web is applied.
  • the method provides that the longitudinal profile and / or transverse profile the mass of binder applied over the Machine width is regulated or controlled.
  • This regulation can be designed such that the masses of the applied binder by a section Change in concentration of the applied binder solution takes place.
  • This has the advantage that the amount of only a small amount of solvent to be evaporated Result in changes.
  • Advantageous values for the area application of the binder are in the range of an average area loading of the paper from 0.05 to 5 gr / m 2 of otro binder, a concentration of the binder solution of 2 to 30% by weight, preferably 15 to 20% by weight, preferably 10 to 15% by weight, can be used advantageously.
  • the nozzles the nozzle humidifier on average 0.03 l / min to 5 l / min, preferably 0.05 l / min to 3 l / min, preferably 0.06 l / min up to 1 l / min, enforce binder solution.
  • Binder For an optimal connection between the applied Binder and the paper web should be the paper web one Dryness greater than 55%, preferably greater than 60%, preferably greater than 80%, if the binder is applied.
  • Figure 1 shows the overview of an inventive Paper machine with a sheet forming unit 1, which here as Twin wire former is formed. Then there is one Press section 2 with two press shoes, one of which Dryer section 3 connects, in which according to the invention - here not shown - nozzle dampers are housed. Then the smoothing 4 follows in the likewise Nozzle can be provided and the reel 5 in which the finished paper web is rolled up.
  • the drying section 3 is again more detailed in FIG. 2 shown. It is a single row Dryer section with two in a manner known per se Nozzle dampers 6 and 7 are equipped, which in this Image only arranged on one side of the paper web are.
  • the percentages above the dryer section shown represent the dryness of the through the dryer section continuous paper at the respective position. According to the invention there is the possibility itself known nozzle dampers for applying a binder use. You can also use additional nozzle dampers be attached, which is also the second side of the Provide drying paper web with binder.
