Abstract

Die Erfindung betrifft ein Verfahren zur Herstellung einer Faserstoffbahn, insbesondere Papier- und/oder Kartonbahn, aus einer Stoffsuspension, die von einem Stoffauflauf geliefert wird, dessen Stoffauflaufdüse (18) mit wenigstens einer Lamelle (10) versehen ist, mit den folgenden Verfahrensschritten:

  • es wird wenigstens eine Lamelle (10) mit einer zumindest bereichsweise strukturierten Oberfläche verwendet,
  • die Strukturierung (16) wird insbesondere so gewählt, dass im Innern des Suspensionsstrahles Querströmungen erzeugt werden, die zu Scherströmungen im Suspensionsstrahl führen.
The invention relates to a method for producing a fibrous web, in particular paper and / or board web, from a stock suspension supplied by a headbox whose headbox nozzle (18) is provided with at least one sipe (10), comprising the following method steps:
  • at least one lamella (10) with an at least partially structured surface is used,
  • the structuring (16) is chosen in particular so that transverse flows are generated in the interior of the suspension jet, which lead to shear flows in the suspension jet.

Weiterhin betrifft die Erfindung einen Stoffauflauf einer Maschine zur Herstellung einer Faserstoffbahn, insbesondere Papier- und/oder Kartonbahn, durch Durchführung des erfindungsgemäßen Verfahrens.
