Description
belegten Siebtrommeln gebildeten Zusammenführungsspaltes eine Dosiereinrichtung für festes Gut angeordnet ist, deren Austrittsöffnung genau in den Zwickel zwischen den in dem Spalt zusammenlaufenden Viiesbahnen mündet, sowie durch anschließende Transportvorrichtungen zum Weitertransport der dreischichtigen Vliesbahn zu einer an sich bekannten Heißluft-Heizeinrichtunc. Durch die spiegelbildliche Anordnung ergibt sich ein sehr übersichtlicher Aufbau, der ein leichtes und genaues Überwachen der Arbeitsweise der einzelnen Teile ermöglicht. Dabei werden jeweils die Fasern in den beiden Einrichtungen zu jeweils einer Faserbahn auf den zugehörigen Saugtrommeln gesammelt und anschließend die beiden Faserbahnen unmittelbar zwischen den gleichen Saugtrommeln vereinigt. Das Zusatzmaterial wird dabei unmittelbar vor der Vereinigung der beiden Fasfbahnen zwischen diese eingebracht. Die weitere Verdichtung undoder Verfestigung der Bahn erfolgt mit den an sich bekannten Heißluft-Heizeinrichtungen. Trotz der zweischichten Bahn ist das pulverförmige Bindemittel in der Gesamtdicke der fertigen Bahn gleichmäßig verteilt. Die beiden ursprünglich gesondert erzeugten Faserbahnen schließen das in dem Zwickel zwischen den beiden Walzen eingebrachte Material sandwichartig ein, wobei Art und Natur des eingebrachten festen Gutes in weiten Bereichen variieren können. So kann das durch die Dosiereinrichtung eingebrachte Gut dazu dienen, das spezifische Gewicht der Fa.-.erbahn zu verändern, die Schalldämmungs- und Wärmedämmungseigenschaften zu beeinflussen oder auch um die Festigkeit der Faserbahn zu erhöhen.occupied sieve drums formed merging gap a metering device for solid material is arranged, the outlet opening opens exactly into the gusset between the converging Viiesbahnen in the gap, as well as through subsequent transport devices for the further transport of the three-layer nonwoven web to a known hot air heating device. Due to the mirror-image arrangement results in a very clear layout, which enables easy and accurate monitoring of the operation of each part e r. The fibers are collected in each of the two devices to form a fiber web on the associated suction drums and then the two fiber webs are combined directly between the same suction drums. The additional material is introduced between the two fascia panels immediately before they join. The further compression and / or consolidation of the web takes place with the hot air heating devices known per se. Despite the two-layer web, the powdery binder is evenly distributed throughout the entire thickness of the finished web. The two originally separately produced fiber webs sandwich the material introduced into the gusset between the two rollers, whereby the type and nature of the solid material introduced can vary within wide ranges. The material introduced by the metering device can serve to change the specific weight of the company, to influence the sound and heat insulation properties or to increase the strength of the fiber web.
Die Frfindung wird nachfolgend an Hand einer schemaiischen Zeichnung an einem Ausführungsbeispiel näher erläutert.The invention is illustrated below with the aid of a schematic drawing of an exemplary embodiment explained in more detail.
Die beiden Vorrichtungen, deren jede die Umwandlung der Fasern zu einer Schicht vornimmt, sind symmetrisch und somit gegensinnig in einer Flucht angeordnet Jede Vorrichtung enthält eine selbsttätige Bcschickungs- und Wägevorrichtung 1, Γ. welche die geöffneten Fasern auf ein endloses Förderband 3, 3' bringt, über welchem sich das Gerät 2, 2' zur Dosierung der Kunstharze und gegebenenfalls der Fülltrichter zur Lieferung von Zusatzstoffen befinden. Ein Speisewalzenpaar 4, 4' bringt die so mit Zusatzstoffen versehenen Fasern zu einer Tromme! 5, 5', welche mit starken Stahlspitzen versehen ist und bei ihrer schnellen Drehung die Fasern abnimmt und trennt und sie in eine geschlossene Kammer 6, 6' schleudert, in welcher sie von einer gelochten Trommel 7, 7' angesaugt werden. Die Fortschleuderung und Ansaugung ermöglicht die Herstellung einer innigen Mischung der Fasern mit dem von der Dosiervorrichtung ausgegebenen Kunstharz und gegebenenfalls mil Zusatzstoffen, insbesondere Feuerschutzmitteln. Das Gemisch tritt unter Pressung durch eine Walze 8, 8' an der Trommel 7, T aus, welche mit einem von einer Walze 10, 10' gespannten endlosen Gitter 9, 9' versehen ist.The two devices, each of which converts the fibers into a layer, are symmetrical and thus arranged in opposite directions in alignment. Each device contains an automatic loading and weighing device 1, Γ. which brings the opened fibers onto an endless conveyor belt 3, 3 ', above which the device 2, 2' for metering the synthetic resins and, if necessary, the hopper for supplying additives are located. A pair of feed rollers 4, 4 'brings the fibers thus provided with additives to a drum! 5, 5 ', which is provided with strong steel tips and, as it rotates rapidly, removes and separates the fibers and hurls them into a closed chamber 6, 6', in which they are sucked in by a perforated drum 7, 7 '. The ejection and suction enables the production of an intimate mixture of the fibers with the synthetic resin dispensed by the metering device and optionally with additives, in particular fire retardants. The mixture exits under pressure through a roller 8, 8 'on the drum 7, T , which is provided with an endless grid 9, 9' stretched by a roller 10, 10 '.
Ein Lüfter 11 dient zur Ansaugung der gemischten und mit Harz umhüllten Fasern, welche so die beiden ziemlich kompakten Schichten 12 und 12' bilden, welche von den endlosen Gittern angetrieben werden. Jede Trommel?, 7' besitzt eine Abschirmung 19, 19', welche das Ansaugen der Fasern der Schichten 12, 12' verhindert, wenn diese unter den Preßwalzen 8, 8' hindurchgegangen find.A fan 11 is used to suck in the mixed and resin-coated fibers, which thus form the two rather compact layers 12 and 12 ', which are driven by the endless grids. Each drum ?, 7 'has a shield 19, 19' which prevents the fibers of the layers 12, 12 'from being sucked in if they have passed under the press rollers 8, 8'.
Der Zwischenraum zwischen den Trommeln 7 und T ist regelbar, um entweder den Austritt der beiden Schichten 12 und 12', deren Dicke einzeln durch die ίο Stellung der Preßwalzen 8 und 8' regelbar ist, gegeneinandergedrückt vorzunehmen, oder den Austritt dieser beiden Schichten 12 und 12' so vozunehmen, daß zwischen ihnen ein Zwischenraum bleibt, welcher gestattet, durch das Dosiergerät 13 verschiedene X5 Werkstoffe zur Bildung eines Sandwichs einzuführen. In beiden Fällen wird das, schichtförmige Erzeugnis am Austritt aus den endlosen Giltern 9, 9" auf ein waagerechtes endloser Förderband 14 gebracht, welches es auf ein schräges Förderband 15 bringt. Das ao doppelte endlose Förderband 16 bringt das Erzeugnis in einen Polymerisierofcn 17, wo das zwischen zwei endlosen gitterförmigen Förderbändern zusammengepreßte Sandwich in an sich bekannter Weise einem heißen Luftstrom ausgesetzt wird, welcher as durch obere und untere Düsen 18 durch die Förderbander und das Sandwich geblasen wird.The space between the drums 7 and T can be regulated in order to either push the exit of the two layers 12 and 12 ', the thickness of which can be regulated individually by the position of the press rollers 8 and 8', or the exit of these two layers 12 and 12 12 'in such a way that a gap remains between them, which allows the dosing device 13 to introduce different materials to form a sandwich. In both cases, the layered product at the exit from the endless gels 9, 9 ″ is brought onto a horizontal endless conveyor belt 14, which brings it onto an inclined conveyor belt 15. The double endless conveyor belt 16 brings the product into a polymerizing oven 17, where the sandwich compressed between two endless lattice-shaped conveyor belts is exposed in a manner known per se to a hot air stream which is blown through upper and lower nozzles 18 through the conveyor belts and the sandwich.
D'" für d'e beiden Vorru -nungen zur Schichtbüd '-ig gewähi-e Anordnung gestattet, zwei Schichten gleicher oder verschiedener Dicke zu bilden und sie insbesondere aus verschiedenen Werkstoffen herzustellen, z. B. eine Schicht aus Baumwollfasern und die andere Schicht aus Fasern aus Jute. Wolle od. dgl. Die verschiedene Dicke ermöglicht die Veränderung der Dichte einer jeden Schicht und somit des spezifischen Gewichts. Eine der Schichten kann Zusatzstoffe enthalten, z. B. Feuerschutzmittel.D '"for the two preliminary rulings for the shift Any arrangement chosen allows two layers to form the same or different thicknesses and in particular to manufacture them from different materials, z. B. one layer of cotton fibers and the other layer of fibers made of jute. Wool or the like. The different thickness enables the density of each layer to be changed and thus the specific gravity. One of the layers may contain additives, e.g. B. Fire retardants.
Dank des Vorhandenseins des Dosiergeräts 13 kann leicht ein nicht gewebter Filz in Sandwichform hergestellt werden, indem /wischen die beiden gleichartigen oder verschiedenartigen Schichten gleicher oder verschiedener Dicke geeignete Werkstoffe eingeführt werden, z.B. Mineralien, Schlacken, Asbest. Holzmehl, Schaumstoffe od. dgl., welche gegebenenfalls mit gewissen Harzen gemischt sind. Man kann so entweder das spezifische Gewicht der Sandwichanordnung vergrößern oder ihre Schalldämmungs- und Wärmedämmungseigenschaften verbessern. Thanks to the presence of the metering device 13, a non-woven felt in sandwich form can easily can be produced by wiping the two layers of the same type or of different types or of different thicknesses suitable materials are introduced, e.g. minerals, slag, asbestos. Wood flour, foams or the like, which may be mixed with certain resins. Man can either increase the specific weight of the sandwich arrangement or increase its sound insulation and improve thermal insulation properties.
Außerdem ei moglicht die erfindungsgemäße Apparatur, gegebenenfalls zwischen die beiden Faserschichten eine Bewehrung zu bringen, um die Zugfestigkeit der Sandwichanordnung zu vergrößern oder ihr eine gewisse Steifigkeit zu erteilen. Diese Bewehrung kann ein Gewebe aus Textilstoff oder aus Metall oder auch ein Netz von Glasfaden, Metallfaden od. dgl. sein, welche in der Längsrichtung des Erzeugnisses angeordnet sind.In addition, the apparatus according to the invention is possible if necessary, to bring a reinforcement between the two fiber layers in order to increase the tensile strength to enlarge the sandwich arrangement or to give it a certain rigidity. This reinforcement can be a fabric made of textile or metal or a network of glass thread, metal thread or the like, which are arranged in the longitudinal direction of the product.
Das obige Verfahren ermöglicht also die fortlaufende einfache zweckmäßige und billige Herstellung von Erzeugnissen ganz verschiedener Art, welche auf den verschiedensten Gebieten zahlreiche Anwendungen finden können.Thus, the above method enables simple, convenient and inexpensive manufacture to continue of products of very different kinds, which have numerous applications in the most varied of fields can find.
