Abstract
Die betreffenden Staubfilterbeutel weisen miteinander verschweißte Wandungen aus einem thermoplastische Anteile enthaltenden Vliesstoff auf. Eine der Wandungen ist mit einer Einströmöffnung versehen, hiermit fluchtet die Durchströmöffnung eines darauf außenseitig aufgebrachten Halteflansches. In die Durchströmöffnung des Halteflansches steht eine ringförmige Dichtung vor. Diese Dichtung wird von einer gummielastischen Lage gebildet, die ein entsprechendes Durchgangsloch aufweist und auf der die Einströmöffnung aufweisenden Beutelwandung fixiert ist.The dust filter bag in question have welded together walls of a nonwoven thermoplastic parts containing. One of the walls is provided with an inflow opening, hereby aligns the flow opening of a retaining flange applied thereto on the outside. In the flow opening of the retaining flange is an annular seal. This seal is formed by a rubber-elastic layer having a corresponding through hole and is fixed on the inflow opening having the bag wall.
Description
Die Erfindung bezieht sich auf ein Verfahren gemäß den Merkmalen des Oberbegriffs des Patentanspruchs 1 und auf einen Staubfilterbeutel mit den Merkmalen des Oberbegriffs des Anspruchs 4.The The invention relates to a method according to the features of the preamble of claim 1 and on a dust filter bag with the features of the preamble of claim 4.
Ein
entsprechender Staubfilterbeutel ist beispielsweise aus der
Solche Staubfilterbeutel weisen im Bereich der Einströmöffnung des Staubfilterbeutels eine Dichtung aus einem gummielastischen Material, insbesondere aus Gummi, auf. Hierbei ist die Gummidichtung Teil des Halteflansches, bei dem es sich vornehmlich um einen aus mehreren Papplagen gebildeten Flansch handelt. Die Gummilage zur Bildung der in die Durchströmöffnung des Halteflansches vorstehenden Ringdichtung ist zwischen zwei benachbarten Papplagen eingeklebt, so daß sie lagesicher gehalten ist. Aufgrund der Elastizität des verwendeten, weichen Gummimaterials wird eine gute Dichtwirkung erzielt. Andererseits ist die Konfektionierung der Halteflansche fertigungstechnisch aufwendig.Such Dust filter bags have in the region of the inflow opening of the dust filter bag a seal made of a rubber-elastic material, in particular made of rubber, on. Here, the rubber seal is part of the retaining flange, in which it is primarily a made of several cardboard plagues Flange acts. The rubber layer to form the in the flow-through of the Holding flange protruding ring seal is between two adjacent Pap patches glued in, so they is held securely. Due to the elasticity of the used, soft Rubber material is achieved a good sealing effect. on the other hand is the assembly of retaining flanges production technically complex.
Die
Aus
dem Dokument
Der Erfindung liegt die Aufgabe zugrunde, einen Staubfilterbeutel und ein Verfahren zu dessen Herstellung zu schaffen, mit dem eine gute Dichtwirkung zwischen dem Staubsaugerstutzen und dem Staubfilterbeutel erlangt und eine einfachere Fertigung ermöglicht wird, indem die Anordnung der gummielastischen Dichtung unabhängig von der Ausführung des Halteflansches ist.Of the Invention is based on the object, a dust filter bag and to provide a process for its production, with which a good Sealing effect between the vacuum cleaner nozzle and the dust filter bag attained and a simpler manufacturing is made possible by the arrangement the rubber-elastic seal regardless of the execution of the Retaining flange is.
Diese Aufgabe wird zum einen mit den Verfahrensmerkmalen des Anspruchs 1 und zum anderen mit den gegenständlichen Merkmalen des Anspruchs 4 gelöst.These Task is firstly with the method features of the claim 1 and on the other with the subject features of the claim 4 solved.
Für die Erfindung ist wesentlich, zum einen die Schmelzfähigkeit des gummielastischen Materials und/oder der thermoplastischen Anteile im Vliesstoff zu nutzen, um die die Ringdichtung bildende gummielastische Lage an der die Einströmöffnung aufweisenden Beutelwandung zu fixieren. Die angeschmolzenen thermoplastischen Anteile im Vliesstoff der Beutelwandung und das insbesondere punktuell angeschmolzene gummielastische Material verschmelzen in der Regel nicht miteinander, sie sind infolgedessen nicht miteinander verschweißbar. Zum einen kann es jedoch auf die sich entwickelnden Hafteigenschaften des angeschmolzenen thermoplastischen Materials ankommen, zum anderen ist wichtig, daß vor allem bei punktueller Wärmeeinwirkung auf das gummielastische Material bei entsprechender mechanischer Beanspruchung pfropfen- oder nietförmige Erhebungen herausformbar sind, die in den Vliesstoff der betreffenden Beutelwandung eindringen oder ihn durchdringen, womit eine Verkrallung des gummielastischen Materials mit dem Vliesstoff erzielt wird. Im übrigen werden die thermoplastischen Anteile des Vliesstoffs, bei dem es sich um ein sogenanntes synthetisches Material handelt, dazu genutzt, die Beutelwandungen miteinander zur Bildung eines kissenartigen Staubfilterbeutels mit zu verschweißen. Der die Beutelwandungen bildende Vliesstoff kann aus zwei oder mehreren Lagen bestehen, wobei zumindest eine dieser Lagen die für die Schweißbarkeit erforderlichen thermoplastischen Anteile enthält.For the invention is essential, on the one hand, the melting ability of the rubber-elastic Material and / or the thermoplastic components in the nonwoven to use the rubber-elastic layer forming the ring seal the having the inflow opening To fix bag wall. The melted thermoplastic Shares in the nonwoven fabric of the bag wall and the particular molten at certain points Rubber-elastic material usually does not fuse together, As a result, they are not welded together. On the one hand However, it may depend on the evolving adhesive properties of the arrive at melted thermoplastic material, on the other is important that before especially with selective heat on the rubber-elastic material with appropriate mechanical Grafting stress or rivet-shaped Elevations are formed in the nonwoven fabric of the relevant Bag wall penetrate or penetrate it, causing a claw of the rubber-elastic material is achieved with the nonwoven fabric. Furthermore become the thermoplastic portions of the nonwoven fabric in which it is a so-called synthetic material, used to the bag walls together to form a pillow-like Dust filter bag with to weld. The bag walls forming nonwoven fabric may consist of two or more layers, at least one of these layers being for weldability contains required thermoplastic components.
Die die elastische Ringdichtung bildende gummielastische Lage wird auf der Innenseite derjenigen Beutelwandung angeordnet, welche die Einströmöffnung aufweist. Dieser Fertigungsschritt ist somit unabhängig von der Herstellung und Bereitstellung des am Filterbeutel außenseitig anzubringenden Halteflansches, der deshalb aus unterschiedlichen Materialien, wie Pappe oder Kunststoff, bestehen kann. Grundsätzlich kann die gummielastische Lage auch auf der Außenseite der die Einströmöffnung aufweisenden Beutelwandung angeordnet werden, hierbei muß darauf geachtet werden, daß das Format der gummielastischen Lage so auf das Format des Halteflansches abgestimmt ist, daß die Befestigung für den Halteflansch nicht beeinträchtigt wird.The the elastic ring seal forming rubber-elastic layer is on arranged on the inside of that bag wall, which has the inflow opening. This manufacturing step is thus independent of the production and Provision of the filter bag to be mounted on the outside retaining flange, therefore made of different materials, such as cardboard or plastic, can exist. in principle The rubber-elastic layer may also have on the outside of the inlet opening Bag wall are arranged, it must be ensured that the format of the rubber-elastic layer adapted to the format of the retaining flange is that the Attachment for the retaining flange is not affected becomes.
