Abstract

Die Erfindung betrifft eine Regeleinrichtung zur Feuchteregelung einer Papierbahn in einer Trockenpartie, welche mindestens einen beheizbaren Trockenzylinder aufweist, wobei ein Betriebsregler vorgesehen ist, mit welchem die den Trockenzylindern zugeführte Wärmemenge auf einen Sollwert regelbar ist, wobei eine Vorsteuereinrichtung vorhanden ist, aus welcher der Sollwert vorbestimmbar und mittels einer Einrichtung zur Bestimmung eines Feuchte-Ist-Wertes korrigierbar ist. Weiterhin betrifft die Erfindung eine Trockenpartie mit einer solchen Regeleinrichtung sowie ein darauf basierendes Verfahren zur Feuchteregelung einer Papierbahn.
