Definitions

  • the invention relates to a method according to the preamble of claim 1.
  • the present invention is directed to the production of multi-ply packaging paper or paperboard, including e.g. Paper or board machines with Mehrlagenstoffauflauf or more headboxes are used. In this case, the position of the cover fabric with fibers of greater length (long pulp) and the layers of the back and / or middle layer with fibers of short length (short fiber) is formed.
  • a packaging paper produced by means of the method or a correspondingly produced cardboard has a cover layer whose composition of matter has the advantage of good optical quality. Since the short fiber fraction formed has an increased number of fibers and a reduced average fiber length in comparison to the starting material, it particularly fulfills the requirements for a blanket layer. Opacity, printability and surface appearance are particularly important for this layer.
  • the method shown process represents the essential process steps of the invention with reference to an example.
  • the pulp solution 1 in which the waste paper M is treated together with water W so that an aqueous pulp suspension S forms.
  • a more or less complex cleaning 2 of the pulp suspension S is necessary. What effort is required to produce a clean pulp is known per se.
  • the cleaning can be omitted.
  • the subsequent fractionation 3 two fiber fractions are formed, of which the short fiber fraction F1 is enriched with short fibers and the long fiber fraction F2 with long fibers.
  • the fractions F1 and F2 thus formed may possibly be further processed in the subsequent part of the stock preparation 4 and then arrive in the two machine huts 5 and 6, respectively.
  • the paper machine 9 generates therefrom the cardboard or the packaging paper.
  • the horizontally separated chambers are supplied via a fuel pump 7 with the short fiber fraction F1 from the machine chest 5 or via a fuel pump 8 with the long fiber fraction F2 from the machine chest 6.
  • an upper material jet 11 containing the short fiber fraction F1 is formed and a lower substance jet 12 containing the long-fiber fraction F2.
  • the ceiling layer 13 (FIG. Fig. 2 ) and from the lower fabric jet 12, the backsheet 14th
  • a particularly suitable fractionator for this purpose is a pressure sorter for wet sifting of the sort of a pressure sorter. This is the DE 199 13 515 A1 a specially designed slotted screen for such a fractionator removed. But even with highly efficient hydrocyclones, so-called cleaners, it is possible to carry out a fractionation according to fiber flexibility.
  • Fig. 2 shows a two-ply packaging paper with a cover layer 13 and a rear side layer 14.
  • the cover layer 13 is provided in many cases with an imprint 16.
  • the upper side 15 of the cover layer 13 has a good printable surface due to the high short fiber content.
  • Another advantage is the high opacity, which means that any existing impurities of the underlying layer or layers little disturb.
