Abstract

Die Erfindung betrifft ein Verfahren zur Herstellung von gestauchtem oder ungestauchtem Sackpapier, bei dem die Bahn (2) in einer Papiermaschine (3) hergestellt wird, was den Stoffauflauf auf ein Sieb, die Entwässerung in einer Presse und die Trocknung in einer Trockenpartie umfasst, und anschließend mittels einer Aufwicklung (8) aufgewickelt wird.The invention relates to a method for the production of compressed or unsteamed sack paper, in which the web (2) is produced in a paper machine (3), which comprises the headbox on a sieve, the dewatering in a press and the drying in a dryer section, and then wound up by means of a winding (8).

Die Erfindung betrifft weiterhin ein Sackpapier, das nach dem Verfahren hergestellt wurde und einen Papiersack aus dem nach dem Verfahren hergestellten Sackpapier. Um die Bedruckbarkeit zu verbessern, wird die Bahn (2) am Ende oder nach der Papiermaschine (3) in einem Breitnipkalander (12) behandelt.
