  Filter zur Reinigung von Luft und für   ähnliche   Zwecke. 



   Bei bekannten Luftreinigern bestehen die Filterelemente aus einem gitterartigen Rahmen, der eine aufgeklebt oder auf andere Art   befestigte, durchbrochelle Watteschicht   oder eine entsprechende Schicht aus anderem faserartigen Stoff trägt. wobei die Durchbrechungen gegeneinander versetzt angeordnet   sind.   Derartige Filterelemente besitzen eine Anzahl von Nach-   teilen. Wenn nämlich der Gitterträger   mit kleinen Maschen versehen ist, so kreuzen die Drähte dieser Meinen. Maschen den freien Querschnitt der Durchbrechungen der Filterplatte.

   Hieraus ergibt sich, dass der freie Querschnitt der Durchbrechungen des Filterelementes vermindert wird, wobei diese Verminderung während der Arbeit des Filters sehr schnell weiter fortschreitet. da die Staubteile sich an den die Durchbrechungen kreuzenden Fäden festsetzen, sich dort anhäufen und schliesslich die Durchbrechungen des Filterelementes ganz oder zum   grossen   Teil 
 EMI1.1 
   der Gitterdrähte   mit den Durchbrechungen nur   zufällig   hier und da eintreten. so dass sie ver-   nachlässigt werden können.   Aber ein anderer   Ubelstand stellt   sich ein : das so gestaltete Filter-   element     ist wenig haltbar ;

   ausserdem bereitet   die Reinigung Schwierigkeiten, denn die geringste 
 EMI1.2 
   Element unbrauchbar.   



   Zur Vermeidung aller oben erwähnten   Cbelstände   sind die Filterelemente nach der Er-   findung nuttels Blättern   aus Watte oder   ähnlichem   geeigneten faserigen Stoff hergestellt, die je auf einem Tragblatt aufgeklebt oder befestigt sind, wobei die ganze. aus dem Blatt faserigen Stoffes und dem Tragblatt zusammengesetzte Platte durchbrochen ist, und zwar so. dass die

  Filters for air purification and similar purposes.



   In known air purifiers, the filter elements consist of a grid-like frame which carries a perforated layer of cotton wool or a corresponding layer of other fibrous material that is glued on or otherwise fastened. wherein the openings are arranged offset from one another. Such filter elements have a number of disadvantages. For when the lattice girder is provided with small meshes, the wires of these mine cross. Mesh is the free cross-section of the openings in the filter plate.

   This results in the free cross-section of the openings in the filter element being reduced, this reduction proceeding very rapidly during the operation of the filter. since the dust particles adhere to the threads crossing the perforations, accumulate there and finally the perforations of the filter element in whole or in part
 EMI1.1
   of the grid wires with the openings only happen randomly here and there. so that they can be neglected. But another problem arises: the filter element designed in this way is not very durable;

   In addition, the cleaning causes difficulties, because the least

   Element unusable.



   In order to avoid all of the abovementioned Cbelstands, the filter elements according to the invention are made of nuttels sheets of cotton or similar suitable fibrous material, each glued or attached to a carrier sheet, the whole from the sheet of fibrous material and the support sheet composite plate is perforated, namely so. that the
