Description
Kopiermaschine. Gegenstand der Erfindung ist eine Anordnung der Walzen zum Auspressen der feuchtten Kopierbahn und zum Kopieren der Schriftstücke in Kopiermaschinen, derart, daß die beiden weichen Walzen zum Auspressen der feuchten Kopierbahn und die eine von ihnen zusammen mit der harten Kopierwalze zum Kopieren dienen.Copy machine. The invention relates to an arrangement of the rollers for pressing out the damp copy web and for copying the documents in copying machines, such that the two soft rollers for pressing out the moist copy web and one of them together with the hard copy roller are used for copying.
Es hat sich nämlich gezeigt, daß zwei Weichgummiwalzen die Feuchtigkeit des Papiers leichter und gründlicher beseitigen, als wenn die eine aus Hartmaterial und die andere aus Weichgummi besteht. Wegen des leichteren Auspressens bedarf es daher auch nicht der hohen Antriebskraft an der Maschine, wodurch wiederum die Gummiwalzen mehr geschont werden.It has been shown that two soft rubber rollers remove the moisture of the paper can be removed more easily and thoroughly than if the one made of hard material and the other is made of soft rubber. Because it is easier to squeeze out, it is necessary therefore not the high driving force on the machine, which in turn causes the rubber rollers be spared more.
Von der zweiten Weichgummiwalze läuft die entwässerte, aber immer noch feuchte Kopierpapierbahn zur harten Kopierwalze, deren Baustoff an sich beliebig ist, und hierbei erfolgt der Kopiervorgang, da bekanntlich zur Herstellung sauberer, also nicht verwischter, klarer Kopien eine Weichgummiwalze auf einer Hartwalze arbeiten muß.The drained roller runs from the second soft rubber roller, but always still moist copy paper web to the hard copy roller, the building material of which is arbitrary is, and here the copying process takes place, as is known to produce cleaner, So not smudged, clearer copies work a soft rubber roller on a hard roller got to.
Hierbei ermöglicht die harte Kopierwalze, wenn sie einen entsprechenden Umfang hat, das mehrfache Kopieren eines Schrift-Stückes hintereinander, ohne Unterbrechung und ohne Papierverlust.The hard copy roller enables this, if it has a corresponding one Scope, the multiple copying of a piece of writing in a row, without interruption and without paper loss.
Bei dem in der Zeichnung in einer Ausführungsform in Fig. r in Seitenansicht und in Fig. a in Draufsicht mit teilweisem Schnitt dargestellten Walzensatz sind e und d die beiden erfindungsgemäß aus Weichgummi bestehenden Walzen, die .die aus den Wasserlasten k von der Vorratswelle g her kommende und an der Walze na geführte Kopierpapierbahn f zwischen sich auspressen. Die Papierbahn geht dann zwischen der Gegendruckwalze d und der harten Kopierwalze b hindurch über die Papierförderwalze a zur Aufwickeltrommel oder zwischen den Zugwalzen i hindurch zu der Abschneidevorrichtung..In the set of rollers shown in the drawing in an embodiment in Fig. R in side view and in Fig Press out the copy paper web f that is coming and is guided on the roller na between you. The paper web then goes between the counter-pressure roller d and the hard copy roller b through the paper feed roller a to the take-up drum or between the pull rollers i to the cutting device.
