Description

Pate ν τ- Anspruch:Godfather ν τ- claim:

Druckwalzenanordnung für Kopiermaschinen mit mehreren Druckstellen, dadurch gekennzeichnet, daß zwei oder mehr Druckwalzen (c1, c") zu gemeinsamer Bewegung und Anpressung gegen die Hartgummihauptwalze (d) vereinigt sind, zum Zweck, den zu kopierenden Bogen und das Kopierpapier beim Kopieren einer Reihenfolge von Druckwirkungen auszusetzen .Pressure roller arrangement for copying machines with several printing points, characterized in that two or more pressure rollers (c 1 , c ") are combined for common movement and pressure against the hard rubber main roller (d) for the purpose of copying the sheet to be copied and the copy paper in a sequence exposure to pressure effects.

Hierzu 1 Blatt Zeichnungen.1 sheet of drawings.

KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. Die Erfindung betrifft Kopiermaschinen der gebräuchlichen Art, bei denen eine exzentrisch gelagerte Druckwalze während des Kopierens das Kopierpapier und den betreffenden Bogen gegen die Hartgummiwalze anzupressen hat. Die Erfindung macht von der an sich bekannten Anordnung mehrerer Druckstellen in der Weise Gebrauch, daß die eine bewegliche Druckwalze durch zwei oderThe invention relates to copying machines of the usual type, in which an eccentric stored print roller during copying the copy paper and the relevant Has to press the sheet against the hard rubber roller. The invention makes of the known arrangement of several pressure points in such a way use that the a movable platen by two or ίο mehr zu gemeinsamer Bewegung vereinigte Walzen ersetzt ist. Hierdurch wird erzielt, daß nur für den eigentlichen Arbeitsvorgang des Kopierens statt des einfachen ein zwei- oder mehrfacher Druck auf das Kopierpapier und den zu kopierenden Bogen ausgeübt wird.ίο more united in common movement Rolling is replaced. This ensures that only for the actual work process of copying instead of simply printing two or more times on the copy paper and the bow to be copied is exercised. In der Zeichnung ist eine zur Ausführung der neuen Vorrichtung geeignete Anordnung beispielsweise dargestellt.In the drawing is a suitable for the implementation of the new device Arrangement shown for example. Die bekannte, durch Exzenter wirkende Anpreßvorrichtung wirkt von der Exzenterwelle α aus auf das den beiden Druckwalzen c', c" gemeinsame Lager, das in einem Schlitz des Gestelles gegen die Wirkung, einer Feder d in bekannter Weise verschiebbar ist.The known pressure device acting by eccentric acts from the eccentric shaft α on the bearing common to the two pressure rollers c ', c " , which can be displaced in a known manner in a slot in the frame against the action of a spring d. Die beiden Druckwalzen c', c" berühren einander nahezu, so daß das Papier nicht in der Lage ist, zwischen den beiden Druckwalzen herauszutreten.The two pressure rollers c ', c " almost touch each other so that the paper is unable to come out between the two pressure rollers. Es kann für das Druckwalzenpaar jede zweckdienliche Anpreßvorrichtung gewählt werden, wobei es nicht unbedingt erforderlich ist, beiden Druckwalzen ein gemeinsames Lager zu geben. Es kommt nur darauf an, daß die Anpressung der Druckwalzen gleichzeitig und, falls es die Aufgabe erfordert, in gleichem Maße geschieht.Any suitable pressing device can be selected for the pair of pressure rollers be, whereby it is not absolutely necessary, both pressure rollers a common one To give stock. All that matters is that the pressure of the pressure rollers is applied simultaneously and, if the task requires it, happens to the same extent.
