Abstract

Die Erfindung betrifft ein Verfahren zur Trocknung von Faserstoffbahnen, insbesondere Papier-, Karton- oder Tissuebahnen, bei dem die Faserstoffbahn aufgeheizt wird.The invention relates to a method for drying fibrous webs, in particular Paper, cardboard or tissue webs in which the fibrous web is heated.

Aufgabe der Erfindung ist es dabei ein Trocknungsverfahren zu schaffen, bei dem ein möglichst ebenes Querprofil des Flächengewichts selbst nach relativ kurzen Trocknungsvorgängen gewährleistet ist.The object of the invention is to provide a drying process in which a as flat as possible cross profile of the basis weight even after a relatively short one Drying processes is guaranteed.

Erreicht wird dies dadurch, daß zumindest während einer Phase des Trocknungsvorganges der Grad der Trocknung wenigstens abschnittsweise quer zur Faserstoffbahn (1) beeinflusst wird.

Figure 00000001
This is achieved in that the degree of drying is influenced at least in sections transversely to the fibrous web (1) at least during one phase of the drying process.
