  VerfahrenzumWlederbrauchbarmachenabgenutztenDurchschreibpapieres. 



   Vorliegende Erfindung betrift ein Verfahren, um abgenutztes Durchschreibpapier (Karbon-und Indigopapier) wieder brauchbar zu machen. 



   Durchschreibpapiere, die teuer im Anschaffungspries sind, werden schon nach verhältnismässig kurzer Zeit unbrauchbar, obwohl ihnen ene noch ganz erhebliche Menge an Farbstoff anhaftet, die natürlich verloren geht. 



   Das vorliegende Verfahren ermöglicht, solche abgenutzte Durchschreibpapiere ohne Neuaufbringung von Farbstoff wieder verwendbar zu machen. so dass eine vollkommene Ausnutzung der gesamten, anfänglich aufgebrauchten Farbachiehte stattfindet. 
 EMI1.1 
 durch das Aussehen wie ein noch unbenutzten   Blatt erhält, ist   wieder verwendbar. 



   Das Verfahren lässt sich an einem und demselben Blatt einigemal wiederholen, so dass ein vollkommenes Ausnutzen des teuren Farbstoffes erfolgt
Das Verfahren lässt sich auch derart ausführen, dass das Papier durch ein Walzenpaar hindurchgeführt wird, von welchen die mit der   Papierruckseite   zusammenwirkende Walze heizbar ist, während die andere Walze als Wischwalze (Verreibungswalze) wirkt und infolgedessen mit grösserer Geschwindigkeit als die Heizwalze umläuft. 



   Es kann auch eine flache Heizplatte benutzt worden, die mit einer Verreibungswalze zusammenarbeitet. 



   Wichtig ist die gloichzeitigo Einwirkung von Wärme und eines Farbverreibungsmittels auf das Papierblatt.

  Method of rendering worn carbonless paper usable.



   The present invention relates to a method for making worn carbonless paper (carbon and indigo paper) usable again.



   Carbonless papers, which are expensive to buy, become unusable after a relatively short time, although they still have a considerable amount of dye adhering to them, which is of course lost.



   The present method enables such worn carbonless papers to be made reusable without reapplication of dye. so that a complete utilization of the entire, initially used up color stream takes place.
 EMI1.1
 by the appearance of a still unused sheet, is reusable.



   The process can be repeated several times on the same sheet, so that the expensive dye can be used to the full
The method can also be carried out in such a way that the paper is passed through a pair of rollers, of which the roller that interacts with the back side of the paper can be heated, while the other roller acts as a wiping roller (distribution roller) and consequently rotates at a greater speed than the heating roller.



   A flat heating plate can also be used which cooperates with a distributor roller.



   What is important is the global exposure to heat and a color dispersant on the paper sheet.
