Abstract

Zum Beleimen von Fasern mit mindestens einer Komponente eines Bindemittels (11) für die Herstellung von Formkörpern aus den mit dem Bindemittel verleimten Fasern, insbesondere von Faserplatten, werden die Fasern in Wasserdampf suspendiert durch eine düsenförmige Verengung (4) eines Blasrohrs (3) hindurchgeführt, das sich von einem die Fasern in heißem und feuchtem Zustand unter Druckentspannung in das Blasrohr abgebenden Refiner zu einem an das Blasrohr anschließenden Trockner für die Fasern erstreckt. Die Komponente des Bindemittels (11) wird im Bereich dieser Verengung (4) auf der Achse (10) des Blasrohrs (3) in der Hauptbewegungsrichtung der Fasern mit einer Düse (9) auf die Fasern aufgedüst.

For gluing fibers with at least one component of a binder (11) for the production of moldings from the fibers glued with the binder, in particular fibreboards, the fibers suspended in water vapor are passed through a nozzle-shaped constriction (4) of a blower tube (3), which extends from one of the fibers in a hot and humid state under pressure release in the blowpipe emitting refiner to a subsequent to the blower dryer for the fibers. The component of the binder (11) is sprayed onto the fibers in the area of this constriction (4) on the axis (10) of the blower tube (3) in the main direction of movement of the fibers with a nozzle (9).
