Abstract

Die Erfindung betrifft ein Verfahren zum Herstellen einer Faserstoffbahn, z.B. Papierbahn, insbesondere in einer Papierherstellungsmaschine und außerdem eine Vorrichtung zum Durchführen dieses Verfahrens.The invention relates to a method for producing a Fibrous web, e.g. Paper web, especially in a Papermaking machine and also a device for Perform this procedure.

Ausgehend von der DE 42 18 595 soll ein stabiler Lauf der Papierbahn insbesondere bei hohen Geschwindigkeiten gewährleistet und die Gefahr von Bahnabrissen verringert werden.Starting from DE 42 18 595, a stable run of the Paper web especially at high speeds guaranteed and the risk of web breaks is reduced will.

Erreicht wird dies dadurch, daß man die Anzahl der - für das Erzielen eines mittleren Bahn-Trockengehaltes (z.B. 60 %) notwendigen - individuell antreibbaren Aggregate (z.B. Trockengruppen) abhängig macht von der sogenannten Initialen Naßfestigkeit (INF), derart daß man bei einer relativ geringen INF eine größere Anzahl von individuell antreibbaren Aggregaten vorsieht als bei einer relativ hohen INF.

Figure 00000001
This is achieved by making the number of individually drivable aggregates (e.g. drying groups) necessary to achieve an average web dry content (e.g. 60%) dependent on the so-called initial wet strength (INF), so that a relative low INF provides a larger number of individually drivable units than a relatively high INF.
