Definitions

  • the invention relates to a headbox for producing a multi-layer paper web or the combination of several single- or multi-layer headboxes for producing a multi-layer paper web and a method therefor.
  • a multilayer headbox is known for example from DE-OS 40 29 545 A1. With independent loading of the individual nozzle spaces with material suspensions, it serves to produce a multilayer paper web. Between the individual nozzle areas of the multi-layer headbox there are swiveling fins that run across the machine width and prevent premature mixing of the different stock suspension flows.
  • paper machines for the production of multilayer paper layers with the aid of several independently acting headboxes are known, as is the case e.g. is described in the published patent application DE 40 31 038 A1.
  • a paper machine is shown in which paper layers are created independently of one another on a plurality of sieves running with one another. can be placed on top of each other before the press section of the paper machine, creating a multi-layer paper.
  • a problem that is not solved with these multilayer and multilayer papers is the adjustment of the fiber orientation and basis weight cross profile.
  • it is very difficult to influence the basis weight in the middle layer at the same time problems arise orifices attached to the nozzle with respect to the fiber orientation of the outer layers.
  • the fiber orientation cross profile setting can be done in a modern headbox by the sectional influence of volume flows, while the basis weight cross profile setting can be done by the sectional influence of the material density.
  • the properties of the individual layers or individual layers differ e.g. in terms of strength, raw material costs, tear behavior and their effect on e.g. the flatness of the sheet or the printability of the paper is fundamental. In this way, e.g. By influencing the fiber orientation of an outer layer or layer in a targeted manner, it is very effective to influence the flatness of the sheet, while a uniform weight per unit area is best influenced by the middle layer.
  • a paper consists of three layers
  • the two outer layers are operated with long-fiber suspension, which is particularly efficient for the effect of the fiber orientation influencing undertaken there, while the middle layer is operated with short fibers, the uniform basis weight cross profile being set in this middle layer becomes.
  • the reason for influencing the flatness of the sheet over the outer layer is that with increasing distance of a layer from the middle layer of the sheet, small tensions in this layer also have an increasing effect on the deformation of the sheet. These deformations are controlled sectionally by influencing the fiber orientation in the outer layer.
  • the efficiency of this procedure is increased in that long fibers are preferably used in the outer layer, which favor the necessary build-up of tension.
  • a particular advantage of the described designs and methods of producing a paper web is that the influencing measures are carried out at the point of their maximum effect and at the same time that the necessary constructive requirements are limited to the absolutely necessary minimum.
  • FIG. 1 it is possible to design a three-layer headbox in such a way that the sectionally supplied material flows of the peripheral layers are only regulated by throttle devices G2 and G3, since this influences the fiber orientation while the central layer is influenced the more complex stock suspension feed with two different stock densities, which are fed sectionally to the central layer via a mixing system.
  • throttle devices G2 and G3 since this influences the fiber orientation while the central layer is influenced the more complex stock suspension feed with two different stock densities, which are fed sectionally to the central layer via a mixing system.
