Abstract

Den Gegenstand dieser Erfindung bilden ein Blattbildungsverfahren und eine geeignete Nasspartie zur Herstellung einer Faserstoffbahn in einer Papier- oder Kartonmaschine mit verbesserter Faserorientierung. Dabei wird in der Nasspartie nach einem Turbulenzblock (3) eines Stoffauflaufs (1) ein Fluid seitlich durch Öffnungen (9, 9') der Faserstoffsuspension zugeführt.

Figure imgaf001
The subject of this invention is a sheet forming process and a suitable wet end for making a fibrous web in a paper or board machine with improved fiber orientation. In this case, in the wet end, after a turbulence block (3) of a headbox (1), a fluid is fed laterally through openings (9, 9 ') of the pulp suspension.
