  Filtertuch. 



   Die Lebensdauer der in Filterpressen zur Verwendung kommenden   Filtertücher   wird ausschliesslich durch den Widerstand bedingt, welchen die zwischen don einzelnen Rahmen eingepressten Randpartien der Tücher der zerstörenden Einwirkung des Klemmdruckes und der Hitze entgegensetzen, weil die Tücher in erster Linie an ihren   Rändern unbrauchbar   werden, und die weitere Verwendungsmöglichkeit der mittleren, den) eigentlichen Filterzwecke dienenden Partien daher gar nicht in Frage kommt. 



   Dieser Nachteil wird weder durch Wahl eines bessren Materiales, noch auch durch das schon   übliche   Aufnähen von Randstreifen behoben, weil das Filtertuchmaterial an sich nicht geeignet ist, der durch Pressung und Hitzeeinwirking bedingten Beanspruchung zu widerstehen, und die Ursache des frühzeitigen Unbrauchbarwerdens der l'ücher eben darin liegt, dass dem vom Standpunkte des Filterprozesses gewahlten Materiale grundsätzlich irriger Weise auch die Aufgabe eines Dichtungsmateriales zugewiesen wird. Um diesem Nachteile zu begegnen, hat man die   Ränder   auch durch Aufnahen von Streifen aus dichtem   Haumwollstoff   oder aus imprägniertem Segeltnch verstarkt. 
 EMI1.1 
   infolgedessen sehr geschont.   



   Für die Herstellung dieser verstärkten Randpartien wird vorzüghch Asbestkautschukmatorial verwendet, wobei das Filtortuch selbst das Einlagementerial zur Herstellung der 
 EMI1.2 
 in Ansicht und einem Querschnitt nach A-B der Fig. 1 gezeigt. Wie aus diesen Darstellungen ersichtlich, ist das Filtertuch m an seinen Randern und an den die Durchlass-   öffnungen   o   begrenzenden Partien durch Anordnung   von   Streifen n aus solchem Dichtungs-     material verstärkt. Die Befestigung der vorzüglich aus Asbestkautschukpräparaten bestehenden   Streifen erfolgt in der Weise, dass das   Fittcrtuch selbst   den Einlagestoff   für die Dichtungs-   
 EMI1.3 
 wege verbunden wird. 



   Die heschriebenen Tücher werden vorzüglcih in Form einfacher Blätter hergestellt,   weiche   mit dem denselben Filterrahmen auf der anderen Seite umfassenden zweiten Tuche durch an der Oberseite angeordnete Ösen oder Schlingen a verbunden wird, welche eventuell in die in bekannter Weise am Oberrande der Rahmen angeordneten Dorne ein-   gehängt   werden.

  Filter cloth.



   The service life of the filter cloths used in filter presses is determined exclusively by the resistance which the edge portions of the cloths pressed in between the individual frames oppose to the destructive effect of the clamping pressure and the heat, because the cloths are primarily unusable at their edges and the further possible uses of the middle parts serving the actual filter purposes are therefore out of the question.



   This disadvantage is not remedied either by choosing a better material or by sewing on edge strips, because the filter cloth material per se is not suitable to withstand the stress caused by pressure and the effects of heat, and the cause of the premature becoming unusable of the towels This is precisely because the material chosen from the point of view of the filter process is, in principle, wrongly assigned the task of sealing material. In order to counteract these disadvantages, the edges have also been strengthened by adding strips of dense hide wool or impregnated sailcloth.
 EMI1.1
   consequently very spared.



   Asbestos rubber material is preferably used for the production of these reinforced edge areas, the filter cloth itself being the insert material for the production of the
 EMI1.2
 shown in view and a cross section according to A-B of FIG. As can be seen from these representations, the filter cloth m is reinforced at its edges and at the parts delimiting the passage openings o by the arrangement of strips n of such sealing material. The fastening of the strips, which are primarily made of asbestos rubber preparations, is carried out in such a way that the fitting cloth itself is the insert material for the sealing
 EMI1.3
 ways is connected.



   The cloths described here are produced in the form of simple sheets, which are connected to the second cloth, which encompasses the same filter frame on the other side, by means of eyelets or loops a arranged on the upper side, which may be inserted into the mandrels arranged in a known manner on the upper edge of the frame. to be hanged.
