Die Erfindung geht von dem Gedanken aus, die Arbeitsgänge bei der Herstellung dieser bekannten Filtereinsätze zu vereinfachen und durch Einsparung der Färmeinit fcel und -vorrichtungen erheblich zu verbilligen. Es wurde -auch ■hi.-rausgefunden, daß bei Filtereinsätzen, deren FaItenabschnitte nicht zu Taschen gestaltet sind und daher stirnseitig dichtende Endsclieiben erfordern, die Herstellung in gleicher ¥eise . wirtschnf tlicher dtirchgeführt werden kann»The invention is based on the idea, the operations to simplify the manufacture of these known filter inserts and by saving the Färmeinit fcel and devices considerably cheaper. It was-also ■ found out, that with filter cartridges, their trap sections are not are designed to form pockets and therefore require sealing end closures at the front, which are manufactured in the same way . can be carried out more economically »

Nach der Erfindung besteht das Dochtmaterial aus sich, in flüssigem Zustand zu aufschaumfähigen Polyurethan verbindenden reaktiven Kunststoff komponenten, die als Mischgut in eine den sternförmigen Filterkörper aufnehmende Form eingegeben werden« Das Dichtmaterial weist im Endztistand eine schwammartige Struktur mit geschlossener Außenhaut auf«According to the invention the wicking material consists of up to aufschaumfähigen in the liquid state polyurethane connecting reactive plastic components, the receiving than mix in a the star-shaped filter body shape are inputted "The sealing material comprises Endztistand a sponge-like structure with a closed outer skin on"
