Di« Erfindung betrifft einen aus einer in Falten gelegten PilterStoffbahn bestehenden sternförmigen Filtereinsatz«
dessen Innenrändern in sich elastische Dichtringe angebracht und dessen etirnseitige Endflächen gegebenenfalls abgedichtet sind·'The invention relates to a star-shaped filter insert consisting of a pilter fabric sheet laid in folds.
whose inner edges are fitted with elastic sealing rings and whose end faces are sealed if necessary.

Be wurde schon vorgeschlagen, als Profil-Dichtringe Stränge aus einer triebfähigen Gummimuese vorzusehen, die in ein· den vorgefertigten atornffinnigen Filterkörper aufnehmende Form eingelegt werden. Diese Stränge vergrößern sich bei
Wärmeeinwirkung in ihrem Volumen und fließen aufschäumend In die Faltenzwischenräume im Bereich der Innenränder des Filterkörpers ein, wobei sie diesen Rändern angeformt werden·It has already been proposed that, as profile sealing rings, strands made of a rubber mold capable of driving, which are inserted into a form that accommodates the prefabricated filter body in the form of a filter body. These strands enlarge at
The effect of heat in their volume and foaming flow into the gaps between the folds in the area of the inner edges of the filter body, whereby they are molded onto these edges.

Die Erfindung geht von dem Gedanken aus· die Arbeitsgänge bei der Herstellung diener bekannten Filtereinsätze au vereinfachen und durch Einsparung der Värmenittel und -vorrichtungen erheblich zu verbilligen. Es wurdo nuch h rau»gefunden, daß bei Filtereinsätzen» deren Paltonabeehnitte nloht zu Taschen gestaltet sind und daher stiraeeitlg dichtende Endschoiben erfordern, die Herstellung in gleicher Woiee wirtschaftlicher durchgeführt werden kann«The invention is based on the idea of the operations Simplify the production of the known filter inserts and save on heating means and devices considerably cheaper. It was also found rough, that in the case of filter inserts »their paltona attachment does not work are designed to bags and therefore stiraeeitlg sealing End caps require manufacture in the same week can be carried out more economically «

Nach der Erfindung beisteht das Dichtmaterial aus sich in flüssigem Zustand au aufschaumfähigen Polyurethan verbin, denden reaktiven Kunst» to f fkotgponent en, die als Mischgut in eine den sternförmigen Fllterkö~rj>er aufnehmende Form eingegeben werden. Das Dichtmatorial weist im Endzustand eine schwammartige Struktur mit geschlossener Außenhaut auf«According to the invention, the sealing material assists itself in the liquid state is combined with foamable polyurethane, the reactive art »to fkotgponent s, which as mixed material in entered a shape that accommodates the star-shaped filter body will. In the final state, the sealing material has a sponge-like structure with a closed outer skin on "
