Obwohl in den zitierten Schriften Maßnahmen zur Vereinfachung von Schweißvorgängen vorgeschlagen werden, ist grundsätzlich das Zusammenschweißen von Filtertaschen mit der Haltevorrichtung vorgesehen. Das aufwendige Schweißen im gesinterten Zustand der Filtertaschen bleibt also bestehen. Es besteht daher Bedarf nach einem Partikelfilter, der ein einfacheres, kostengünstiges Herstellungsverfahren ermöglicht. Insbesondere sollte das Verfahren auf das Zusammenschweißen der Filtertaschen mit der Haltevorrichtung verzichten.Even though Measures in the cited documents proposed to simplify welding operations be, is basically the welding together provided by filter bags with the holding device. The elaborate welding So in the sintered state of the filter bags remains. It There is therefore a need for a particulate filter which is a simpler, cost-effective Manufacturing process allows. In particular, the process should be based on the welding together of the Dispense filter bags with the holding device.
Vorteile der ErfindungAdvantages of invention
Der erfindungsgemäße Partikelfilter bzw. das Verfahren zu seiner Herstellung hat den Vorteil, dass der Partikelfilter einfacher hergestellt werden kann als bisher aus dem Stand der Technik bekannt. Insbesondere kann der erfindungsgemäße Partikelfilter ohne einen Schweißvorgang der Filtertaschen mit der Haltevorrichtung hergestellt werden und gewährleistet dennoch eine gute Fixierung und zuverlässige Festigkeit der Verbindung zwischen den Bauteilen. Gleichzeitig wird eine ausreichende Abdichtung erzielt.Of the Particle filter according to the invention or the process for its preparation has the advantage that the Particle filter can be made easier than before known in the art. In particular, the particle filter according to the invention without a welding process the filter bags are made with the holding device and guaranteed nevertheless a good fixation and reliable strength of the connection between the components. At the same time a sufficient seal achieved.
Das erfindungsgemäße Verfahren ermöglicht weiter sehr vorteilhaft, dass die Filtertaschen im Ausgangszustand sowohl im nicht gesinteren, d. h. grünen Zustand als auch im gesinterten Zustand vorliegen dürfen. So kann das Verfahren vielfältig angewandt werden.The inventive method allows further very advantageous that the filter bags in the initial state both in non-sintered, d. H. green state as well as in the sintered Condition may be present. So the process can be varied be applied.
Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben und in der Beschreibung beschrieben.advantageous Further developments of the invention are specified in the subclaims and described in the description.
