Abstract

Verfahren zur Herstellung eines plattenförmigen, schallabsorbierenden Elementes und plattenförmi­ ges, schallabsorbierendes Element. Process for the production of a plate-shaped sound-absorbing element and plate-shaped Ges, sound absorbing element.

Plattenförmige, schallabsorbierende Elemente müssen sowohl optischen als auch akustischen Anforderungen genügen und sollen auf möglichst einfache und kostengünstige Weise herstellbar sein. Panel-shaped, sound-absorbing elements must be both optical and acoustic Requirements meet and should meet as much as possible simple and inexpensive to manufacture be.

Erfindungsgemäß wird hinsichtlich des Verfahrens aus einem bandförmigen, vliesartigen Material ein endloses Rohr gefertigt, das Rohr wird in Rohrabschnitte (2) vorgegebener Länge zerteilt und die Rohrabschnitte (2) werden parallel zu­ einander mit ihren Mantelflächen (3) zur Ausbil­ dung des plattenförmigen Elements (1) miteinan­ der verbunden. Das plattenförmige, schallabsor­ bierende Element weist erfindungsgemäß mehrere parallel zueinander angeordnete, im Bereich ihrer Mantelflächen (3) miteinander verbundene Rohrabschnitte (2) aus einem vliesartigen Material auf. According to the invention with regard to the method made of a band-shaped, fleece-like material an endless pipe is made, the pipe is in Cut pipe sections (2) of predetermined length and the pipe sections (2) are parallel to each other with their lateral surfaces (3) for training extension of the plate-shaped element (1) with each other the connected. The plate-shaped, sound absorber element has several according to the invention arranged parallel to each other in the area their lateral surfaces (3) interconnected Pipe sections (2) made of a non-woven Material on.

Die Erfindung ist bei allen Arten von schall­ absorbierenden Elementen anwendbar. The invention applies to all types of sound absorbent elements applicable.
