Definitions

  • the invention relates to a production method for a rotogravure paper having a maximum roughness depth of 1.40 ⁇ m (measured by the " P arker P rint S urf" method according to DIN ISO 8791-4).
  • the filler content or pigment content of the pulp suspension is kept as high as possible, since these very fine materials produce a very smooth and homogeneous surface of the paper.
  • a pulp is used, which has as high a degree of grinding as possible, due to the high proportion of Fine material to produce a homogeneous sheet structure. Uniformity and closeness of the paper surface are of paramount importance.
  • gravure paper is currently being produced in part by producing coated base paper as a highly tear-resistant paper and subsequently coating the paper surface with pigment and filler in order to obtain sufficient surface quality.
  • This requires a high investment cost, since in addition to the paper machine necessary for the production of the paper, even in a coating machine, which works on-line or off-line to the papermaking process, must be invested.
  • CSF Canadian Standard Freeness
  • the inventors have realized that it is possible to produce a gravure paper using a pulp with a low freeness with values greater than 50 ml CSF, preferably between 50 ml and 120 ml CSF, without on-line or on-line coating
  • To use "off-line" operation if it is possible to arrange the filler or pigment content of the finished paper web for the most part in the immediate surface near the finished paper web, on the one hand, the tensile strength of the produced gravure paper is increased and on the other hand, the maximum surface roughness of the paper is not affected. At the same time, however, the manufacturing process takes place in one operation.
  • the dry content of the fibrous web, to which the filler and / or the pigment is applied ⁇ 90%, preferably 3% to 55%, preferably 5% to 20%, since only this way a good binding of the filler or of the pigment is achieved on the fiber web.
  • a high total filler content requires a smaller relative proportion of the strength-generating pulp portions at a constant basis weight. This makes it necessary to use higher quality and therefore more expensive fiber fractions.
  • the invention of the targeted application of pigments to the surface of the paper avoids this disadvantage. It can thus be used without loss of quality cheaper fiber materials.
  • the filler content concentrates substantially in the layers close to the surface or surface forming layers which are important for printing, while in the middle of the sheet there is a low filler content which in itself already ensures good tear resistance of the paper, wherein additionally by reducing the Grinding degree over the prior art to a freeness greater than 50 ml of CSF is additionally provided for an increase in the tensile strength of the paper.
  • This also means that the web receives better runnability by the paper machine and later by a printing press.
  • An advantageous embodiment of the production method provides that subsequent to the at least one order of the pigment and / or Grestoffslurry a press run takes place. By this press flow is achieved that the binding of the pigment and / or filler coating with the fibrous web is increased.
  • the production process can be applied both on one side and on both sides of the fibrous web, so that the pigment and / or filler slurry can also be applied to both sides of the fibrous web.
  • Possible locations for applying the pigment or / and filler slurry layer may be the sheet forming system of the paper machine or the press section.
  • the composition of the pigment and / or filler slurry it is also possible to apply it through a sieve to the fibrous web. In this way, it is advantageously achieved that the application can be applied to the paper web at a time when the tear resistance of the paper web itself is not sufficient to release it from the wire. Even if this were possible, the application process would have an adverse effect on the fiber structure and affect the subsequent tensile strength of the paper web.
  • the order of the pigment and / or filler slurry can therefore also be carried out on a per se already relatively tear-resistant paper web through a sieve in order to reduce the likelihood of a possible web break in the manufacturing process and thus to increase the effective life of the paper machine.
  • Advantageous values for the total coating weight of the at least one application of the pigment and / or filler slurry per side of the paper web is a dry mass of 0.5 to 10.0 g / m 2 , preferably 1.0 to 10 g / m 2 .
  • the production process is not limited to the application of a filler and / or pigment slurry to an already existing fiber web, but rather to it
  • 50 ml to 120 ml of CSF preferably 50 ml to 80 ml of CSF
  • the pulp / fines fraction in the pigment and / or filler suspension preferably in the range 10th % to 95%, preferably 30% to 60%.
  • a fibrous web is formed by means of a headbox having at least two, preferably at least three layers, wherein one layer, preferably the two outer layers, is charged with the filler and / or pigment suspension and at least one layer, preferably the inner layer , is charged with the designated stock suspension.
  • a paper web with the aid of a sheet forming system, a press section and a dryer section, wherein a subsequent coating of the paper web is dispensed with.
  • this method according to the invention it is achieved that in the outer layer to be printed, or in the two outer layers, a very high Gearstoff- and / or pigment content is present, while in a fibrous layer, or in the inner layer, fibers with a relatively low Grinding corresponding to greater than 50 ml of CSF, preferably in the range of 50 ml to 100 ml of CSF, are present, so that here a very good tensile strength of the paper web is guaranteed.
  • At least one of the following may be added: retention aids, dispersants, fixatives, sizing agents, binders and starch.
  • fines suspension can also be used.
  • FIG. 1 illustrates the production method according to the invention with a three-layer headbox 1 and a subsequent twin-wire former.
  • the headbox 1 has three feeds 1.1 to 1.3, wherein the middle feed 1.1 is charged with a stock suspension, which is produced according to the invention with a substance having a freeness greater than or equal to 50 ml of CSF.
  • FIG. 2 shows the course of the relative proportion of filler 6 in a coordinate system in which the relative filler content is plotted on the ordinate and the Z-direction of the paper is shown on the abscissa.
  • the two marginal arrows represent the surfaces of the top (left) and the bottom (right) of the finished paper.
  • the proportion of filler 6 on the top side and the bottom side of the paper reaches a maximum, while in the central region of the paper there is a relatively small proportion of filler. Accordingly, in this area, the proportion of the pulp is high and, according to the invention, has a freeness of greater than 50 ml of CSF. Due to the high filler content in the outer layers of the paper, the optimum printability of the paper for the gravure printing method is achieved, although there is only a reduced degree of grinding of the substance of the inner paper layer. In addition, as a positive side effect also results in an improved runnability of the paper.
  • FIG. 2a Another possible course of relative fiber and filler content is shown in FIG. 2a.
  • the curve 6 shows the relative filler content over the z-direction of the paper
  • the curve 6.1 the course of the relative pulp content of a substance with 50 to 120 ml of CSF
  • the curve 6.2 the course of the relative pulp content of a substance with ⁇ 30 ml of CSF
  • FIG. 3 shows a paper machine with a sheet forming system 7, consisting of a twin-wire former, which is supplied by a single-layer headbox 1 with stock suspension. This is followed by a press section 8 with two shoe presses 8.1 and 8.2. Behind a single-row dryer section 9 is arranged, which is followed by a calender 10. From there, the finished paper is finally led to the winding 11.
  • the arrows 12 to 20 show examples of possible positions for applicators for application of pigment or filler.
  • a first position for an applicator that is to say a first application location, is represented by the arrow 12.
  • This application location is in the region of the transition from the sheet forming system to the press section, that is to say in an area in which the upper wire has already been removed from the fiber web and the fiber web is supported only by a lower wire of the sheet forming system.
  • advantageous application locations are the positions 12A to 12C in the illustrated twin-wire former, whereby here too the sieves are applied.
  • the lower wire is peeled off and the fiber web is taken over by the first upper wire of the press section, with another favorable application point 13 being located in this free section of the second side of the fiber web. Since the fiber web passes through the press 8.1 after the application of the pigment or filler layer, these newly applied layers are optimally "welded" to the fiber web.
  • the dry content of the fiber web has not exceeded a value of 90%, since at a dry content of higher than 90%, only an insufficiently firm connection with the fiber web becomes.
  • a drying content of 3% to 55% is preferred.
