Description
Verfahren zur Herstellung runder, flacher Filtereinsätze.Process for the production of round, flat filter inserts.
Bisher sind runde flache Filtereinsätze aus gefaltetem Material nur in einer Ausführung bekannt, wie sie in unserer Anmeldung P 2137309.I Fig. h, Fig. 6 und Fig. 7 dargestellt sind. Das in obiger Anmeldung beschriebene Verfahren, einen Flachfiltereinsatz herzustellen, ist schwieriger als das in unserer neuen Anmeldung beschriebene.Are previously round flat filter cartridges of pleated material are in one embodiment known as h in our application P 2137309.I Fig., Fig. 6 and Fig. 7. The method described in the above application for producing a flat filter insert is more difficult than that described in our new application.
Weiterhin machen die in Anmeldung P 2137309.I gefertigten Filtereinsätze eine zusätzliche Dichtung nötig, die bei der neuen Erfindung nicht mehr benötigt wird, da die Endscheiben des neuen Flachfiltereinsatzes aus elastischem Material hergestellt sind, das durch Schäumen mit dem Faltenbalg verbunden wird. Dies ist auch in unserer Anmeldung P 23^2155·8 beschrieben.Furthermore, make the filter inserts manufactured in application P 2137309.I. an additional seal is required, which is no longer required with the new invention, since the end plates of the new Flat filter insert are made of elastic material, which is connected by foaming with the bellows. This is also described in our application P 23 ^ 2155 · 8.

Die Verfahrensproblematik für die Anbringung des äußeren und inneren Abdichtrandes für kreisförmige Flachfiltereinsätze entsprechend der Patentanmeldung P 2342155.8, s. auch Fig. VII, i-st augenscheinlich. The procedural problems for the attachment of the outer and inner Sealing edge for circular flat filter inserts accordingly of patent application P 2342155.8, see also Fig. VII, is evident.
Die offenstehenden Falten Fig. IV verlangen eine bisher nicht angewandte Verfahrenstechnik, um den Faltenbalg (l6) einzuschäumen.The open folds Fig. IV require a previously not used Process engineering to foam the bellows (l6).

Das Verfahren dieser Anmeldung zur wirtschaftlichen und technisch einfachen Fertigung geschieht nach folgender Methode. In bekannter Weise werden Faltenbälge aus Filtermaterial hergestellt und für dieses Verfahren verwendet. Der Faltenbalg (l6) wird entsprechend Fig. II in eine mit Dichtungsmaterial gefüllte Form (17) gesteckt. Dabei ist für labile Faltenbälge die Hilfsvorrichtung (25) und (26) zu verwenden. Bei bestimmten Anwendungsfällen kann auch die Verwendung eines Deckels (27) zum Beschweren oder Zentrieren des Faltenbalges nötig sein.The procedure of this application for economic and technical simple production is done according to the following method. In a known manner, bellows are made from filter material and used for used this procedure. The bellows (16) is inserted into a mold (17) filled with sealing material as shown in FIG. II. The auxiliary device (25) and (26) is for unstable bellows to use. In certain applications, the use of a cover (27) may be necessary to weight down or center the bellows.
Entsprechend der Anmeldung P 23^2155.8 kann die Form verschiedene Querschnitte haben. Siehe Fig. Ia- d oder andere.According to the application P 23 ^ 2155.8, the form can be different Have cross-sections. See Fig. 1 a d or others.
Je nach der Eigenschaft des Dichtungsmaterials wird die Entformungszeit festgelegt. Diese gewährleistet, daß der entformte Filterbalg (l6) mit Dichtung (Dichtlippe) in flache, Fig. V, oder winklige Lage, Fig, III, gebracht werden kann, je nach Anwendungsfall. Anschließend wird der eingekippte, Fig. III, oder flache, Fig. V, halbfertige Filtereinsatz in eine Form (19), die mit O-Ringen (20) versehen werden kann, 2 Stück oder mehr gegeben. Nach Bedarf kann Formteil. (21) eingesetzt werden, um Dichtlippe (l8) oder andere Querschnitte entsprechend Fig. I a - d zu erzielen.The demolding time depends on the properties of the sealing material set. This ensures that the demolded filter bellows (l6) with seal (sealing lip) in flat, Fig. V, or angular position, Fig, III, can be brought, depending on the application. Then the tilted, Fig. III, or flat, Fig. V, semi-finished filter insert in a form (19) that can be provided with O-rings (20), 2 pieces or more. To Requirement can be molding. (21) can be used to achieve sealing lip (l8) or other cross-sections according to Fig. I a - d.
Danach wird mittels einer Dosiermaschine Dichtungsmaterial eindosiert und das obere Formteil (22) aufgesteckt.Sealing material is then metered in using a metering machine and the upper molded part (22) attached.
Sobald das Dichtungsmaterial entformbar bzw. ausgeschäumt ist, wird der fertige Flachfiltereinsatz oder der winklige Filtereinsatz entsprechend Fig. III entformt.As soon as the sealing material can be removed from the mold or is foamed the finished flat filter insert or the angled filter insert is removed from the mold as shown in FIG. III.
Die Winkellagen des in Fig. III dargestellten Einsatzes können beliebig verändert werden. Es erfordert eine Änderung der Form Fig. VI.The angular positions of the insert shown in Fig. III can can be changed at will. It requires a change of the form Fig. VI.
