Abstract

Die Erfindung betrifft ein Verfahren zur Erfassung eines Abrisses einer Faserstoffbahn (3) in einer Sektion (2) einer Maschine (1) zur Herstellung der Faserstoffbahn (3), wobei die Faserstoffbahn (3) mittels wenigstens eines zumindest mehrere Bestandteile aufweisenden Bahnträgers (5) durch die Sektion (2) geführt wird, wobei der Abriss durch mindestens eine optische Einrichtung (8) zur Bahnabrisserfassung, die mindestens eine Leuchtquelle (11) und einen Detektor (14) umfasst, erfasst wird und wobei eine Abschlagvorrichtung (9) für die Faserstoffbahn (3) durch die Einrichtung (8) zur Bahnabrisserfassung direkt oder indirekt aktiviert wird.
Das erfindungsgemäße Verfahren ist dadurch gekennzeichnet, dass die von der Faserstoffbahn (3) und/oder von wenigstens einem Bestandteil des Bahnträgers (2) reflektierte Intensität (IR) der Leuchtquelle (11) in einem Wellenlängenbereich (L) zwischen 800 bis 2.600 nm mittels des Detektors (14) gemessen wird, um einen Abriss der Faserstoffbahn (3) zuverlässig zu erfassen.
Weiterhin betrifft die Erfindung eine Vorrichtung (10) zur Durchführung des erfindungsgemäßen Verfahrens.
