   Der Gegenstand der Erfindung betrifft eine Verbesserung derjenigen Art von mechanischen Wischvorrichtungen für   Kupferdruckpressen.   bei welchen die   Wischbalken   (z. B. auf exzentrischen Antriebswellen aufgesetzt) eine   kreisende Bewegung vollfuhren, während   die zu wischenden Platten in Führungen eine im wesentlichen geradlinig fortschreitende Bewegung machen. 



   Die kreisende Bewegung der Wischer ergibt, bezogen auf die geradlinig fortschreitende Bewegung der Kupferplatte eine Relativgeschwindigkeit. die gleich ist der Summe aus der Plattengesehwindigkeit und der in die   Plattenbewegungsrichtung   fallenden   Komponente   der Kreisbewegung des Wischers (wenn beide Organe sich gegeneinander bewegen), jedoch gleich ist der Differenz der beiden erwähnten 
 EMI1.2 
 des Wisehens und damit der erzielten Drucke   unerwünschte   Schwankungen der Relativgeschwindigkeit des Wischers zur Platte wird erfindungsgemäss dadurch gemildert, dass in den Antrieb dieser Kreisbewegung Unrundräder oder analog wirkende Antriebselemente derart eingeschaltet werden, dass der im Sinne der   Plattenbewegung verlaufende Teil   der kreisenden Bewegung des Wischers beschleunigt,

   der entgegengesetzt gerichtete Teil der kreisenden Bewegung des Wischers hingegen verzögert wird, so dass die Relativgeschwindigkeit des Wischers zur Platte und damit die erzielten Drucke gleichförmiger werden.

 EMI1.1
 



   The subject matter of the invention relates to an improvement of that type of mechanical wiping devices for copper printing presses. in which the wiping bars (e.g. placed on eccentric drive shafts) perform a circular movement, while the plates to be wiped make an essentially linear progressive movement in guides.



   The circular movement of the wipers results in a relative speed in relation to the linear progressive movement of the copper plate. which is the same as the sum of the disk speed and the component of the circular movement of the wiper falling in the direction of disk movement (when both organs move against each other), but the difference between the two mentioned is the same
 EMI1.2
 the knowledge and thus the pressure achieved, undesirable fluctuations in the relative speed of the wiper to the plate are alleviated according to the invention in that non-circular gears or analog drive elements are switched on in the drive of this circular movement in such a way that the part of the circular movement of the wiper that runs in the sense of the plate movement accelerates

   on the other hand, the oppositely directed part of the circular movement of the wiper is delayed, so that the relative speed of the wiper to the plate and thus the pressure achieved become more uniform.
