Abstract

Element comprises filter material folded in a zigzag pattern with the ends sealed together. The ends are joined together by applied adhesive which is thermoplastic. Heating can be ultrasonic or the adhesive can be inserted by wire or joined metal foil and which is induction- or resistance-heated. ADVANTAGE - Fast, simple and easily automated

Description

Die Erfindung betrifft ein Ringfilterelement aus zick-zack-förmig gefaltetem Filtermaterial nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a ring filter element filter material folded in a zigzag shape after the Preamble of claim 1.

Bei derartigen Ringfilterelementen soll eine verein­ facht herstellbare Verbindung der Enden geschaffen werden.With such ring filter elements, a club should Foldable connection of the ends created will.

Die erfindungsgemäße Lösung besteht in einer Ausfüh­ rung nach dem kennzeichnenden Teil des Patentan­ spruchs 1.The solution according to the invention consists of an embodiment tion according to the characterizing part of the patent application saying 1.

Zweckmäßige Verfahren zur Herstellung der erfindungs­ gemäßen Verbindung der Filtermaterialenden sind Ge­ genstand der Unteransprüche.Appropriate method for producing the Invention according to the connection of the filter material ends are Ge subject of the subclaims.

Die nach den Unteransprüchen eingebrachten Metalltei­ le sind vorzugsweise mit einem plastifizierbaren Kunststoff, der ein Schmelzkleber (Hotmelt) sein kann, ummantelt bzw. beschichtet.The metal part introduced according to the subclaims le are preferably with a plasticizable Plastic that can be a hot melt can, coated or coated.

Vorteile der Erfindung bestehen in einer Verkürzung der Herstellzeit, einer Verringerung des Materialbe­ darfs für die Verbindung, einer Faltentrennung im Be­ reich des Verbundsteges, einer annähernd vollen Aus­ nutzung der letzten Falte zur Filtration sowie einer ausgezeichneten Möglichkeit zur Automatisierung der Herstellung einer solchen Verbindung.Advantages of the invention are a shortening the manufacturing time, a reduction in material  may for the connection, a fold separation in the loading range of the connecting bridge, an almost full range use of the last fold for filtration and one excellent way to automate the Establishing such a connection.

Ein Ausführungsbeispiel ist in der Zeichnung darge­ stellt, die einen Teil eines Schnittes durch ein Ringfilter zeigt.An embodiment is shown in the drawing represents a part of a section through Ring filter shows.

Zwischen die aneinanderstoßenden Falten 1 und 2 ei­ ner sternförmig gefalteten Filterbahn ist radial au­ ßen ein beidseitig mit Schmelzkleber 3 beschichteter Aluminiumfolien-Streifen 4 eingelegt. Die Verbindung zwischen den Falten 1 und 2 erfolgt durch induktives Erwärmen des beschichteten Streifens 4.Between the abutting folds 1 and 2 egg ner folded filter web is radially outside ß coated on both sides with hot melt adhesive 3 aluminum foil strips 4 . The connection between the folds 1 and 2 takes place by inductive heating of the coated strip 4 .

Das Filtermaterial ist aus nicht schmelzbarem Materi­ al, insbesondere üblichem Filterpapier, das imprä­ gniert sein kann.The filter material is made of non-meltable material al, in particular conventional filter paper, the imprä may be decorated.
