Abstract

Die Erfindung betrifft eine Vorrichtung zur Herstellung einer Faserstoffbahn (10), insbesondere Papierbahn, mit einem Stoffauflauf (3; 40) sowie weiteren Bestandteilen, wie Former (4), Pressenpartie (14), Trockenpartie (21, 29) und insbesondere Streicheinrichtung (25) und/oder Kalander (34).The invention relates to a device for producing a fibrous web (10), in particular a paper web, with a headbox (3; 40) and further components such as a former (4), a press section (14), a drying section (21,29) and in particular a coating device (25 ) and / or calenders (34).

Die erfindungsgemäße Vorrichtung ist dadurch gekennzeichnet, dass der Stoffauflauf (3; 40) eine mehrere Schichten (S1, S2; S1, S2, S3) an Faserstoffteilsuspensionen (2.1, 2.2; 2.1, 2.2, 2.3) führende Düse (7; 41) aufweist, wobei die Faserstoffteilsuspensionen (2.1, 2.2; 2.1, 2.2, 2.3) wenigstens zum Teil aus ein und derselben Faserstoffsuspension (2) gebildet sind, dass die Trockenpartie (21, 29) wenigstens eine einreihige Trockengruppe (22, 30) umfasst, und dass die Ausgestaltung und/oder der Betrieb des Stoffauflaufs (3; 40) allein oder in Kombination mit der Ausgestaltung und/oder des Betriebs wenigstens eines weiteren Bestandteils (21, 22) so gewählt ist, dass sich ein gewünschtes Profil der Layerorientation in z-Richtung hinsichtlich einer Curlbeeinflussung der Faserstoffbahn (10) ergibt.The device according to the invention is characterized in that the headbox (3; 40) has a nozzle (7; 41) which has several layers (S1, S2, S1, S2, S3) on partial pulp suspensions (2.1, 2.2; 2.1, 2.2, 2.3) , wherein the partial pulp suspensions (2.1, 2.2, 2.1, 2.2, 2.3) are formed at least in part from one and the same pulp suspension (2) such that the dryer section (21, 29) comprises at least one single-row dryer group (22, 30) and the configuration and / or the operation of the headbox (3; 40) alone or in combination with the design and / or operation of at least one further component (21, 22) is selected such that a desired profile of the layer orientation in the z-direction with respect to a curl influence of the fibrous web (10).

Weiterhin betrifft die Erfindung ein entsprechendes Verfahren zur Herstellung einer Faserstoffbahn (10).
