Definitions

  • the invention relates to a method for producing a paper web with a headbox according to the preamble of claim 1.
  • Such a headbox should set the stock density and fiber orientation cross profile of the paper stock suspension at the latest before the outlet gap in such a way that the basis weight and fiber orientation cross profile of the paper web corresponds to the desired requirements over the entire width, which generally means that it is constant and at the same time ensures a uniform paper composition.
  • the paper composition is the concentration of the individual components, e.g. Long fibers, short fibers, fillers etc. are meant.
  • DE 35 14 554 proposes to change the consistency locally, i.e. adjust the fabric density at certain points as required. However, it remains open how this should be done.
  • DE 40 19 593 A1 recommends the following procedure: If the basis weight profile of the paper web deviates at a certain point in the web width, the concentration C M of the section stream in question, and thus the stream emerging from the mixer in question, should be changed accordingly. To achieve this, the ratio of the amounts of the control currents Q H / Q L fed to the mixer is changed. With valves of the usual design, however, it is difficult to avoid that the section flow Q M leaving the mixer is also uncontrolled by the setpoint and deviates unintentionally. It is also known from DE-OS 35 38 466 that a change in the volume flow of a section leads to an influence on the fiber orientation angle in the outlet area of the headbox. If the amount of a section stream deviates in an uncontrolled manner from a target value, the fiber orientation also changes in an uncontrolled manner.
  • the invention has for its object to influence the composition cross profile of the fibrous web of a paper machine so that it comes as close as possible to the ideal profile.
  • the composition cross profile can be influenced in a direction that is favorable for production.
  • this non-uniform basis weight cross profile is influenced by aperture deformation or by sectional material density changes with the intention of obtaining an ideal basis weight cross profile.
  • the process can be applied to all headbox types (e.g. single-layer headboxes, multi-layer or multi-layer headboxes, headboxes for gap formers, headboxes for Fourdrinier screens, etc.).
  • headbox types e.g. single-layer headboxes, multi-layer or multi-layer headboxes, headboxes for gap formers, headboxes for Fourdrinier screens, etc.
