Die Erfindung bezieht sieh auf tin Verfahren zur gleichmäßigen Verteilung von aus dem Söhmelzfluiß erzeugtem Mineralfasern auf einem Förderband. Insbesondere bezieht sich die Erfindung auf die Herstellung von Filzen aus Glasfasern oder einem sonstigen anorganischen, wärmebildsamen Material.The invention relates to processes for even distribution of from the Söhmelzfluiß produced mineral fibers on a conveyor belt. In particular, the invention relates to manufacture of felts made of glass fibers or any other inorganic, heat-forming material.

In dem Hauptpatent ist ein Verfahren angegeben, das dadurch gekennzeichnet ist, daß die in einem Luftstrom suspendierten Fasern von der Seite her in einen senkrechten Schacht eigeführt und mit Hilfe von Leitblechen abwärts gerichtet werden, wobei die Leitbleche hin- und zurückschwingende Bewegungen ausführen und so den Faserstrom gleichmäßig über die ganze Breite eines am Boden des Schachtes angeordneten Förderbandes verteilen.In the main patent, a method is specified, which is characterized in that in a stream of air suspended fibers introduced from the side into a vertical shaft and with the help of baffles are directed downwards, with the guide plates swinging back and forth and so the fiber flow evenly over the entire width of a arranged at the bottom of the shaft Distribute the conveyor belt.

Die Erfindung schlägt zur Ausgestaltung des im Hauptpatent angegebenen Verfahrens vor, daß die in dem Luftstrom suspendierten Fasern mittels des oder der Leitbleche in gleknäßiger Verteilung zunächst zumindessens auf einen Teil der Breite des eine Saug·- wirkung auf sie ausübenden Oberflächenbereiches einer umlaufenden gelochten, unter Vakuum stehenden Trommel gerichtet werden und der sieh auf diesem Oberflächenbereich hierbei bildende Filz von einem anschließenden, von dem Vakuum unbeeinflußten Trommeloberflächembereich auf das Förderband abgelegt wird.The invention proposes for the embodiment of the method specified in the main patent that the in Fibers suspended in the air flow by means of the guide plate or plates initially at least in a uniform distribution to a part of the width of the surface area that exerts a suction effect on it revolving perforated drum under vacuum and see on this Surface area in this case forming felt from a subsequent, unaffected by the vacuum Drum surface area deposited on the conveyor belt will.

Der Faserstrom wird vorzugsweise so gerichtet, daß er sich im Zickzack über die Oberfläche der Trommel bewegt, insbesondere bei der Herstellung von Faserfilzen größerer Breite.The stream of fibers is preferably directed to zigzag over the surface of the drum moves, especially in the production of fiber felts of greater width.

Es sind an sich Verfahren bekannt, bei denen Glasfasern od. dgl. einer umlaufenden Trommel zugeführt werden, auf der sie zu einer Glasfilzdecke vereinigt und dann abgezogen werden. Die Trommel ist hierbei gelocht, und durch eine in ihr angeordnete stillstehende weitere gelochte Trommel, die an eine Unterdruckleitung angeschlossen ist, wird auf bestimmten Teilen eine Saugwirkung erzeugt. Ablenkeinrichtungen, die eine gewünschte Dicke des Materials auf der Trommel erzielen lassen, sind bei den bekannten Verfahren nicht vorgesehen.There are known methods in which glass fibers Od. The like. Are fed to a rotating drum on which they are combined to form a glass felt cover and then be peeled off. The drum is perforated and a stationary one arranged in it another perforated drum, which is connected to a vacuum line, is on certain Sharing creates suction. Deflectors providing a desired thickness of the material on the Can achieve drum, are not provided in the known methods.

Die Erfindung soll nunmehr unter Bezugnahme auf die Zeichnung, welche eine Vorrichtung zur Herstellung von Glasfaserfilzen od. dgl. schematisch darstellt, ausführlicher besahrieben werden.The invention will now be made with reference to the drawing, which shows an apparatus for manufacturing of fiberglass felts or the like. Schematically, are described in more detail.

gelochter Oberfläche. Der durch das Leitblech gerichtete Faserstrom geht im Zickzack über die Oberfläche der sich drehenden Trommel, so daß das Fasermaterial gleichmäßig über die Breite der Trommel verteilt wird. Durch Änderung der Schwingung des Leitbleches 8 kann der Faserstrom so gerichtet werden, daß die ganze Breite der Trommel oder nur ein bestimmter Teil derselben von den Fasern bedeckt wird. In der Trommel 14 sind vorzugsweise eine oder mehrere Vakuumvoirrichtungen angeordnet, um ein Vakuum längs jenes Teiles des Trommelumfanges zu erzeugen, wo die Fasern festgehalten werden sollen, wohingegen das Vakuum längs jenes Teiles des Umfanges, von dem der Filz abgenommen werden muß, nicht aufrechterhalten wird. Wenn der in der Zeichnung mit 16 bezeichnete Filz sich ablöst oder von der Oberfläche der Trommel entfernt wird, dann wird er auf ein unterhalb der Trommel gelegenes Förderband 20 übertragen. Auf diesem Förderband kann ein zweiter Filz 22, der durch eine zweite erfindungsgemäße Vorrichtung verfertigt wurde, liegen.perforated surface. The fiber stream directed through the baffle zigzags over the surface the rotating drum so that the fiber material is uniform across the width of the drum is distributed. By changing the vibration of the guide plate 8, the fiber flow can be directed so that the whole width of the drum or only a certain part of it is covered by the fibers will. In the drum 14, one or more vacuum devices are preferably arranged to a To create a vacuum along that part of the drum circumference where the fibers are to be held, whereas the vacuum along that part of the circumference from which the felt must be removed, is not sustained. When the felt designated 16 in the drawing comes off or from the Surface of the drum is removed, then it is placed on a conveyor belt located below the drum 20 transferred. On this conveyor belt, a second felt 22, which is replaced by a second felt according to the invention Device was manufactured, lie.
