Abstract

Die Erfindung betrifft ein Meßsystem zur Bestimmung des Feuchtigkeitsgehaltes einer Papier-, Textil- oder einer anderen Faserstoffbahn (1) in einer Maschine zur Herstellung und/oder Veredlung der Faserstoffbahn (1) in einem Bereich der Maschine in dem die Faserstoffbahn (1) ohne freien Zug, d. h. nicht ungestützt verläuft.The invention relates to a measuring system for determining the moisture content of a Paper, textile or other fibrous web (1) in a machine for production and / or finishing of the fibrous web (1) in an area of the machine in which the Fibrous web (1) without free draft, d. H. does not run unsupported.

Ermöglicht wird dies dadurch, daß die Messung dort erfolgt, wo die Faserstoffbahn (1) auf einer im wesentlichen wasserfreien, mitlaufenden Oberfläche aufliegt.

Figure 00000001
This is made possible by the fact that the measurement takes place where the fibrous web (1) lies on an essentially water-free, moving surface.
