Abstract

Die Erfindung betrifft Verfahren und dazugehörige Vorrichtungen zur Trocknung und Glättung einer Faserstoffbahn (1), insbesondere einer Papierbahn in einer Maschine zur Herstellung und/oder Veredlung derselben, bestehend aus zumindest einer Trockenpartie (2), in der die Faserstoffbahn (1) über mehrere beheizte Zylinder (3) geführt wird und einem Kalander (4) mit mehreren Glättspalten (5).The invention relates to methods and associated devices for drying and smoothing a fibrous web (1), in particular a paper web in one Machine for producing and / or finishing the same, consisting of at least one dryer section (2) in which the fibrous web (1) spans several heated cylinder (3) and a calender (4) with several Smoothing slits (5).

Zur Gewährleistung eines guten Feuchtequerprofils sowie eines guten Glättergebnisses bei hohen Geschwindigkeiten ist es dabei wesentlich, daß die Faserstoffbahn (1) in der Trockenpartie (2) höchstens bis auf einen Trockengehalt von 93% getrocknet und innerhalb der Trockenpartie (2) mehrfach auf das Feuchtequerprofil der Faserstoffbahn (1) Einfluß genommen wird.

Figure 00000001
To ensure a good moisture cross profile and a good smoothing result at high speeds, it is essential that the fibrous web (1) in the dryer section (2) is dried to a dry content of 93% at most and within the dryer section (2) several times on the moisture profile Fiber web (1) is influenced.
