"Strukturen aus zickzackförmigen Folien insbesondere für Filter""Structures made of zigzag-shaped foils, especially for filters"

Priorität der französischen Anmeldung 84 12 590 vom 9. August 1984Priority of the French application 84 12 590 of August 9, 1984

Die vorliegende Erfindung bezieht sich auf zickzackförmige Strukturen entsprechend dem Oberbegriff des Anspruches 1, insbesondere auf Strukturen, die auf der Grundlage von Folienwerkstoffen hergestellt sind, die derart gefaltet und zickzackförmig geformt werden, daß Filtergarnituren entstehen.The present invention relates to zigzag structures according to the preamble of claim 1, in particular on structures made on the basis of foil materials that are folded and zigzag in this way be shaped so that filter sets arise.

Die zickzackförmigen Strukturen werden hauptsächlich durch Eindrücken in den Folienwerkstoff von abwechselnd vertieften und erhöhten zickzackförmigen Linien gebildet, die die Zickzackleisten begrenzen, wobei diese Zickzackleisten unter Druck und unter gleichzeitiger Führung geformt werden.The zigzag structures are mainly through Impressions in the foil material are formed by alternating recessed and raised zigzag lines that form the zigzag strips limit, these zigzag strips are formed under pressure and with simultaneous guidance.

Auf diese Weise bildet man eine Struktur, die nicht nur ziehharmonikaartig gefaltet ist, sondern in welcher jeder sich zwischen den Falten erstreckende Streifen zickzackförmig ist.This creates a structure that is not just accordion-like is folded, but in which each strip extending between the folds is zigzag.

Bei dem bekannten Stand der Technik hat man versucht, solche Strukturen herzustellen, indem man zwei Streifen Folienmaterial Dei gleichzeitigem Einfügen eines biegsamen und verformbaren Streifens zwischen diese faltet, der die Struktur nach derThe known prior art has attempted to produce such structures by placing two strips of sheet material The simultaneous insertion of a flexible and deformable strip between them, which folds the structure according to the

Zickzackformung freilegt. Die auf diese Weise erhaltenen Strukturen sind unsymmetrisch, da die auf einer Seite in einer Ebene liegenden Scheitel der Falten eingedrückt sind, wogegen die auf der anderen Seite in einer Ebene liegenden Falten abgerundet sind. Verschiedene damit durchgeführte Versuche ergeben, daß ein Teil der Garnituren, insbesondere für Luftfilter von Motoren, nicht zu gebrauchen war.Exposing the zigzag. The structures obtained in this way are asymmetrical, as the vertices of the folds lying on one side in one plane are indented, whereas the on the other hand, folds lying in one plane are rounded. Various experiments carried out with it show that some of the sets, especially for engine air filters, could not be used.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, diesen Nachteil zu beseitigen.The present invention is based on the object To eliminate disadvantage.

Diese Aufgabe wird mit dem Merkmal des kennzeichnenden Teils des Anspruches 1 erfindungsgemäß gelöst.This object is achieved according to the invention with the feature of the characterizing part of claim 1.

Dank dieser Anordnung hat man festgestellt, daß ein bedeutender Vorteil für die Rückhaltekapazität eines Luftfilters erhalten werden kann.Thanks to this arrangement, it has been found that a significant benefit is obtained for the retention capacity of an air filter can be.

Die Erfindung wird nun in bezug auf eine besondere Bayform als Ausführungsbeispiel im einzelnen beschrieben, das auf beiliegender Zeichnung wiedergegeben ist. Es zeigenThe invention will now be made with respect to a particular bayform as an exemplary embodiment described in detail on the enclosed Drawing is reproduced. Show it

Fig. 1 eine perspektivische Ansicht einer Struktur gemäß der Erfindung,Fig. 1 is a perspective view of a structure according to the invention,

Fig. 2 eine vergrößert dargestellte Seitenansicht der Struktur gemäß der Erfindung.Fig. 2 is an enlarged side view of the structure according to the invention.

Wie man aus Fig. 1 sieht, ist die zickzackförmige Struktur gemäß der Erfindung aus einem Folienwerkstoff 1 hergestellt, der, um ein ziehharmonikaartiges Element zu bilden, derart gefaltet ist, daß gleiche Streifen 2 vorhanden sind, die von den Falten 3 getrennt sind.As can be seen from Fig. 1, the structure is zigzag produced according to the invention from a film material 1, which, in order to form an accordion-like element, such is folded that the same strips 2 are present, which are separated from the folds 3.

Jeder Streifen 2 ist mit Markierungen 4 in Form von aneinanderstoßenden und aufeinanderfolgenden Parallelogrammen, insbesondere Rechtecken, derart versehen, daß jeder Streifen die Form einer Zickzackleiste annimmt.Each strip 2 is provided with markings 4 in the form of abutting one another and successive parallelograms, in particular rectangles, provided in such a way that each strip the Takes the form of a zigzag strip.

Die Falten 3 sind so hergestellt, daß ihre Böden abgerundet sind, wobei alle Falten gleich sind.The folds 3 are made so that their bottoms are rounded where all folds are the same.

So hat man festgestellt, daß man bei sehr bedeutenden Abmessungen die Leistung von Luftfiltern, die solche Strukturen haben,
verbessern kann.It has been found that, with very significant dimensions, the performance of air filters having such structures
can improve.

Selbstverständlich ist die Erfindung nicht auf das gezeigte und dargestellte Ausführungsbeispiel beschränkt. Man kann zahlreiche Detailänderungen durchführen, ohne den Schutzbereich der Erfindung zu verlassen.Of course, the invention is not limited to the embodiment shown and illustrated. One can do numerous Carry out detailed changes without departing from the scope of protection of the invention.
