Abstract

The filter element is formed from a pleated or corrugated filter web (2), with side strips (3) bonded firmly to the end sides. The side strips (3) are of paper with an adhesive coating, with at least one shear-resistant filament (4) preferably of silk at the adhesive layer which lies along the end sides of the filter web (2) where the side strips (3) are fitted.

Description

Stand der TechnikState of the art

Die Erfindung betrifft ein Filterelement mit zick-zack oder wellenförmig gefalteten Filterbahnen, die an den je­ weiligen Stirnseiten mit einem fest angefügten Seiten­ streifen umgeben sind nach der Gattung des Haupt- und des Nebenanspruchs.The invention relates to a filter element with a zigzag or wave-shaped pleated filter sheets that are attached to each end faces with a firmly attached sides stripes are surrounded according to the genus of the main and the Secondary claim.

Es ist bereits aus der US-PS 5,501,794 ein Filterelement bekannt, daß aus wellenförmig bzw. zick-zack-förmig ge­ falteten Papierfilterbahnen aufgebaut ist. Dieses bekann­ te Filterelement ist an seinem Stirnflächen mit Seiten­ streifen umgeben, die mit einem Klebstoff fest an die Filterbahnen angeklebt sind. Die Seitenstreifen dienen hier an den Stirnflächen zur mechanischen Stabilisierung des gesamten Filterelements. Bei dieser bekannten Anord­ nung besteht der Seitenstreifen vollständig aus einem Ge­ webematerial, daß von dem Material der Filterbahnen un­ terschiedlich ist.It is already a filter element from US Pat. No. 5,501,794 known that from wavy or zigzag ge folded paper filter sheets is built. This got te filter element is on its end faces with sides surround the strips that are firmly attached to the with an adhesive Filter tracks are glued. The side stripes serve here on the end faces for mechanical stabilization of the entire filter element. With this known arrangement  The side stripe consists entirely of one Ge weaving material that un of the material of the filter sheets is different.

AufgabenstellungTask

Der Erfindung liegt die Aufgabe zugrunde, ein Filterele­ ment der eingangs genannten Art so auszubilden, daß es aus einem einfachen recycelbaren Material aufgebaut ist und eine ausreichende Festigkeit aufweist.The invention has for its object a Filterele ment of the type mentioned in such a way that it is made from a simple recyclable material and has sufficient strength.

Vorteile der ErfindungAdvantages of the invention

Das erfindungsgemäße Filterelement ist in vorteilhafter Weise geeignet, ausgehend von der gattungsgemäßen Art, die gestellte Aufgabe mit den kennzeichnenden Merkmalen des Hauptanspruchs zu lösen. Dadurch, daß die Seiten­ streifen ebenso wie die Filterbahnen aus einer Papierbahn hergestellt sind und zusätzlich mit einer Klebeschicht versehenen sind, ist weiterhin ein einfacher Aufbau des Filterelements gewährleistet. Da auf der Klebeschicht mindestens ein reißfester Faden oder ein entsprechendes Band angeordnet ist, kann eine ausreichende Festigkeit des Seitenstreifens erreicht werden.The filter element according to the invention is more advantageous Suitable, starting from the generic type, the task with the characteristic features to solve the main claim. Because the sides strip like a filter web from a paper web are produced and additionally with an adhesive layer provided, is still a simple structure of the Filter element guaranteed. Because on the adhesive layer at least one tear-resistant thread or a corresponding one Band is arranged, sufficient strength of the hard shoulder.

Damit ein sicheres Verkleben und Abdichten der jeweiligen Stirnkante des Filterelemente gewährleistet ist, wird der Faden oder das Band bevorzugt ganz in den Schmelzkleber der Klebeschicht eingebettet. Der mindestens eine Faden kann in vorteilhafter Weise noch zusätzlich in vorgegebe­ nen Abständen an der Papierbahn angeheftet sein.So that the respective pieces are securely glued and sealed The end edge of the filter element is guaranteed Thread or the tape preferably entirely in the hot melt adhesive the adhesive layer embedded. The at least one thread can also be specified in an advantageous manner intervals on the paper web.

Da die Schmelzkleberdicke auf der Papierbahn nur ca. 0,3 mm beträgt, kann auch der Faden hier nur sehr dünn sein. Durch diesen Faden kann somit nicht jedes Einreißen des Seitenstreifens verhindert werden, jedoch ein komplettes Durchreißen ist hiermit verhindert. Mit dem erfindungsge­ mäßen Filterelement ist auf jeden Fall auf einfache Weise ein mechanisches Ausklopfen des Filterelements, um es von Verunreinigungen zu befreien, möglich ohne es zu zerstö­ ren.Since the hot melt adhesive thickness on the paper web is only approx. 0.3 mm is, the thread can only be very thin here. This thread can not tear every  Side stripes can be prevented, but a complete one This prevents tearing. With the fiction moderate filter element is definitely simple mechanically tapping the filter element to get it from Get rid of impurities without destroying it ren.

Weitere vorteilhafte Ausführungsformen sind in den Un­ teransprüchen angegeben.Further advantageous embodiments are in the Un claims specified.

Zeichnungdrawing

Ein Ausführungsbeispiel des erfindungsgemäßen Filterele­ ments wird anhand der Figur der Zeichnung erläutert.An embodiment of the Filterele invention ment is explained with reference to the figure of the drawing.

Beschreibung des AusführungsbeispielsDescription of the embodiment

In der Figur der Zeichnung ist ein Filterelement 1 ge­ zeigt, das zick-zack-förmig gefaltete Papierfilterbahnen 2 zur Luftfilterung aufweist. An den Stirnseiten der Pa­ pierfilterbahnen 2 befinden sich Seitenstreifen 3 eben­ falls aus Papier, die beim dargestellten Ausführungsbei­ spiel innen mit einem reißfesten Faden 4, beispielsweise aus Seide, versehen sind. Der Faden 4 liegt in einer hier nicht erkennbaren Klebeschicht auf der Innenseite der Seitenstreifen 3 und ist darüber hinaus noch an Stellen 5 angeheftet.In the figure of the drawing, a filter element 1 is shown which has zig-zag folded paper filter sheets 2 for air filtering. On the end faces of the Pa pierfilterbahnen 2 are side strips 3 just in case of paper, which are provided with a tear-resistant thread 4 , for example made of silk, in the game shown in the embodiment. The thread 4 lies in an adhesive layer (not recognizable here) on the inside of the side strips 3 and is also attached at points 5 .

Alternativ zum dargestellten Ausführungsbeispiel können auch mehrere Fäden 4 in den Seitenstreifen 3 angebracht werden und es ist auch anstelle der oder des Fadens 4 die Anbringung eines reißfesten Bandes möglich, das bei­ spielsweise auch aus Seide oder auch aus Spezialpapier hergestellt sein kann. As an alternative to the illustrated embodiment, a plurality of threads 4 can also be attached in the side strips 3 and it is also possible to attach a tear-resistant tape instead of the thread or threads 4 , which can also be made of silk or special paper for example.
