Abstract

Die Erfindung betrifft ein Verfahren zur Herstellung einer beschichteten Faserstoffbahn (7), insbesondere aus Papier oder Karton in einer Bahn-Herstellungsmaschine (1) aufweisend folgende Schritte:
- Bahnbildung aus einem Faserstoffgemisch mit einem Stoffauflauf (2) und einer Siebpartie (3);
- Entwässerung in einer Pressenpartie (4);
- Vortrocknung (6), um die gebildete Faserstoffbahn (7) zumindest bis auf einen Restfeuchtegehalt zu trocknen;
- Beschichtung wenigstens einer Seite (7a, 7b) der Faserstoffbahn (7);
- Nachtrocknung (8) und
- Aufrollung (9) der Faserstoffbahn (7).The invention relates to a method for producing a coated fibrous web (7), in particular from paper or board in a web-making machine (1), comprising the following steps:
- web formation from a pulp mixture with a headbox (2) and a wire section (3);
- drainage in a press section (4);
- Predrying (6) to dry the formed fibrous web (7) at least to a residual moisture content;
- coating at least one side (7a, 7b) of the fibrous web (7);
- drying (8) and
- Rolling (9) of the fibrous web (7).

Erfindungsgemäß ist vorgesehen, dass in einem online-Prozess wenigstens eine Bahnseite (7a, 7b) der Faserstoffbahn (7) mindestens dreifach mit Auftragsschichten (11, 17, 18) versehen wird, wobei zumindest die beiden letzten Auftragsschichten (17, 18) mit einem 1:1-Auftragswerk (15) in direkter Weise und ohne Zwischentrocknung, d.h. nass in nass aufgebracht werden.

Figure imgaf001
According to the invention, at least one web side (7a, 7b) of the fibrous web (7) is provided at least three times with application layers (11, 17, 18) in an online process, at least the last two application layers (17, 18) being provided with a 1: 1 application unit (15) directly and without intermediate drying, ie wet on wet.
