    Flächenmessgerät für   Leder und dgl. 



   Gegenstand der Erfindung ist ein Gerät zur Bestimmung des   Flächenmasses   von Leder und   ähnlichen   Stoffen. Unter den bisher bekanntgewordenen, dem gleichen Zwecke dienenden Vorrichtungen gibt es einerseits solche, bei welchen ein mehr oder weniger unverändert starker, durch einen Ventilator erzeugter,

 in der Art, dass der von einem Ventilator erzeugte Luftstrom nicht unmittelbar zur Messung der   Fläche,   sondern nur zur Betätigung von Kontakten verwendet wird, durch welche Widerstände in einem Stromkreis so ein-oder ausgeschaltet werden, dass die dadurch veränderte Stromstärke in diesem Stromkreis ein

   Die Deckplatte besteht aus einem Blech B, welches nach oben durch eine isolierende Schicht C gedeckt ist, weil dieses Blech gleichzeitig zur Stromzuführung dient. An der Unterseite des Bleches sind Blattfedern t befestigt, welche unterhalb der Löcher b zu kleinen Schälchen vertieft sind und sich mit einem Fortsatz auf die auf Isolatoren I angebrachten Kontakte anlegen können. von diesen Kontakten führen Leitungen zu den   Widerständen tu   und weiters zu einer Sammelschiene S. 



   Während nun durch die vom Leder bedeckten Bohrungen keine Luft zutreten kann, tritt durch

   Durch diese Einrichtung ist man unabhängig von der Umlaufzahl des Vertilators, vom veränder-

    Area measuring device for leather and the like.



   The invention relates to a device for determining the areal measure of leather and similar materials. Among the devices that have become known so far and that serve the same purpose, there are on the one hand those in which a more or less unchanged strong, generated by a fan,
 EMI1.1
 in such a way that the air flow generated by a fan is not used directly to measure the area, but only to actuate contacts through which resistors in a circuit are switched on or off in such a way that the amperage in this circuit changed as a result
 EMI1.2
 



   The cover plate consists of a sheet B, which is covered at the top by an insulating layer C, because this sheet is also used for power supply. On the underside of the metal sheet, leaf springs t are attached, which are recessed to form small bowls below the holes b and can be applied to the contacts on insulators I with an extension. Lines lead from these contacts to the resistors tu and further to a busbar S.



   While no air can enter through the holes covered by the leather, it does so

 Contacts. The current limited by the resistors M 'is measured by an ammeter or wattmeter, the division of which is set up in such a way that the number of not
 EMI1.4
 Leather can be lifted off, which means that the measuring table is ready for another measurement.



   With this facility you are independent of the number of revolutions of the fan, of the changing
