Abstract

It has been impossible for the filter units known hitherto to be manufactured in the desired variety and in a cost-effective manner. In order to produce filter mats for a wide variety of intended uses cost-effectively, it is proposed to hold two ground threads at a distance from one another by means of pile loops on a stitch-bonding machine and to introduce granular or pulverulent filter materials via a tube plate between the two basic fabrics thus formed.

Description

Die Erfindung bezieht sich auf ein Verfahren zur Herstellung einer Filtermatte gemäß dem Oberbegriff des Hauptanspruches und auf eine Vorrichtung zur Durchführung dieses Verfahrens.The invention relates to a method for Production of a filter mat according to the generic term of the main claim and a device for Performing this procedure.

Die Herstellung von Filtermatten stellt eine Aufgabe für die heute umweltbewußte Zeit dar, da derartige Filtermatten einfacher zu handhaben sind als feste Filterkörper, ihre Auswechselbarkeit erleichert wird und damit das häufige Ersetzen derartiger Filtermatten durch neue Matten vereinfacht wird.The production of filter mats is a task for today's environmentally conscious time, because such Filter mats are easier to handle than fixed ones Filter body, their interchangeability facilitated and thus the frequent replacement of such filter mats is simplified by new mats.

Das Herstellen derartiger Filtermatten stößt aber auf bisher unüberwindliche Schwierigkeiten.The production of such filter mats, however, comes up against on previously insurmountable difficulties.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren anzugeben, mit dem derartige Filtermatten unter geringfügigen Änderungen bestehender Maschinen kostengünstig hergestellt werden können.The invention has for its object a method specify with which such filter mats under minor changes to existing machines can be produced inexpensively.

Diese der Erfindung zugrundeliegende Aufgabe wird durch die Lehre des Hauptanspruches gelöst.This object underlying the invention will solved by the teaching of the main claim.

Eine Vorrichtung zur Durchführung des Verfahrens ist im Unteranspruch erläutert.An apparatus for performing the method is explained in the subclaim.

Es ist bekannt, Nähwirkwaren mit Polschlingen herzustellen, wobei zwei Warenbahnen mit Abstand zueinander verarbeitet werden (DE-AS 12 67 372). It is known to sew knitwear with pile loops produce, with two webs at a distance from each other are processed (DE-AS 12 67 372).  

Bei dem erfindungsgemäßen Verfahren wird so vorgegangen, daß zwischen die beiden Grundwaren, welche durch Polschlingen im Abstand voneinander gehalten werden, ein Füllstoff eingebracht wird, der als Filtermaterial ausgebildet sein kann, z. B. pulverförmig oder körnig ist und z. B. aus Aktivkohle, Sand usw. besteht. Derartige Füllstoffe, die über Adsorption und/oder Absorption als Filtermaterial für gasförmige oder flüssige Stoffe wirken, sind an sich bekannt. Gemäß der Erfindung wird ein konfektionierbares Filtermaterial produziert, das pulverförmige oder feinkörnige Filterstoffe als Flächengebilde anbietet.In the method according to the invention proceeded like this that between the two basic goods, which are separated by pole loops be held a Filler is introduced as the filter material can be formed, for. B. powdery or granular is and z. B. consists of activated carbon, sand, etc. Such Fillers that have adsorption and / or absorption as filter material for gaseous or liquid substances are known per se. According to The invention becomes a ready-to-use filter material produces the powdery or fine-grained Offers filter fabrics as fabrics.

Das Füllmaterial wird während des Herstellungsprozesses der Nähwirkware in den Zwischenraum zwischen den beiden Grundwaren eingefüllt, und zwar durch ein Füllröhrchen, wobei hier eine Röhrchenplatine Anwendung findet. Die Füllmenge zwischen den beiden Grundwaren ist je nach Durchmesser bzw. Höhe der Polröhrchen bzw. nach der Länge der Abstandsfäden variabel.The filling material is used during the manufacturing process the knitted fabric in the space between filled in the two basic goods, namely by a Filling tube, here a tube board application finds. The fill amount between the two Basic goods are depending on the diameter or height Pole tube or according to the length of the spacer threads variable.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnung erläutert. Die Zeichnung zeigt dabei inAn embodiment of the invention is as follows explained using the drawing. The drawing shows in

Fig. 1 schaubildlich einen Ausschnitt aus einem erfindungsgemäßen Filtermaterial und in Fig. 1 shows a section of a filter material according to the invention and in

Fig. 2 in einer schematischen Darstellung in Seitenansicht den Aufbau der Nähwirkstelle. Fig. 2 shows a schematic representation in side view of the structure of the sewing point.

In der Zeichnung ist mit 1 die eine Grundware, mit 3 die andere Grundware und mit 2 das zwischen die beiden Grundwaren eingefüllte Filtermaterial bezeichnet. Mit 4 ist ein Nähfaden bezeichnet, der als Fixierung des Abstandes zwischen den beiden Grundwaren dient.In the drawing, 1 denotes one basic product, 3 the other basic product and 2 the filter material filled between the two basic products. 4 with a sewing thread is designated, which serves to fix the distance between the two basic goods.

Die bisher bekannte Polplatine beim "Malipol-Verfahren" ist in eine Röhrchenplatine 5 umgeändert, die an eine Füllvorrichtung anschließt und damit ein kontinuierliches Zuführen des Füllmaterials zwischen die beiden Grundwaren 1 und 3 ermöglicht.The previously known pole plate in the "Malipol method" has been changed into a tube plate 5 , which connects to a filling device and thus enables the filling material to be fed continuously between the two basic goods 1 and 3 .

Mit 6 ist eine Gegenhaltebarre bezeichnet, die als zusätzliche Gegenhaltebarre zur Vermeidung des Verschiebens der zweiten Grundware 3 und damit zur Erzielung einer störungsfreien Maschenbildung dient. 6 with a counter-holding bar is designated, which serves as an additional counter-holding bar to avoid the displacement of the second basic fabric 3 and thus to achieve a trouble-free stitch formation.

Mit 7 ist in Fig. 2 eine Nähnadel, mit 8 ein Schließdraht, mit 9 eine Abschlagbarre und mit 10 eine Nähfadenlochnadelbarre bezeichnet, wobei bei 11 die an sich bekannte Stützschiene dargestellt ist. 7-2 is in FIG. A sewing needle, 8 a locking wire, denoted by 9 is a tee bar and with 10 a Nähfadenlochnadelbarre, wherein, in 11, the support rail is known per se is shown.
