Description

Verfahren zur Herstellung eines Papiers für Schecks oder ähnliche Schriftstücke. Um bei Schecks und ähnlichen Schriftstükken Fälschungen durch Entfernung der Schrift mittels Oxa:säure, Hypochloriten usw. zu verhindern, hat man in solche Papiere organische Farbstoffe oder andere Stoffe hineingebracht; welche bei jener Behandlung ihre Farbe verlieren oder ändern. Sicherer sind jene Verfahren, bei weichen gleich Tinte als Indikator benutzt wird, weil hierbei eine gleichzeitige Reaktion von Schrift und Indikator auf das Entfernungsmittel unter allen Umständen zu erwarten ist.Process for making a paper for checks or the like Documents. In order to counterfeit checks and similar documents by removing them to prevent the writing by means of oxa: acid, hypochlorites, etc., one has in such Papers, organic dyes or other substances put in; which at that Treatment will lose or change color. Those procedures are safer with soft the same ink is used as an indicator, because this is a simultaneous reaction of writing and indicator on the removal means to be expected under all circumstances is.

Ein solches Verfahren, welches Tinte im Papier zu diesen Zwecken benutzt, ist bekannt. Es ist jedoch sehr umständlich, denn es wird hier eine stark mit Tinte usw. gefärbte Papierschicht zwischen zwei oder mehrere nicht oder nur schwach gefärbte saugfähige Deckschichten gelegt und zusammengegautscht.Such a process, which uses ink in the paper for these purposes, is known. However, it is very cumbersome, because it gets heavily inked here etc. colored paper layer between two or more uncolored or only slightly colored absorbent cover layers laid and squeezed together.

Das vorliegende Verfahren bringt ebenfalls Tinte auf das Papier, jedoch in einer bisher nicht benutzten Art: Papierfasern werden mit fertiger Tinte gefärbt oder es wird Tinte in solchen durch die bekannte Doppelzersetzung erzeugt. Diese Fasern werden auf eine Papierbahn aufgespritzt, während diese sich noch auf dem Sieb der Papiermaschine oder dahinter befindet. Durch den Druck der Trockenzylinder erfolgt eine innige Vereinigung der beiden Faserarten. Es entsteht so ein einseitig meliertes Papier, weiches die oben geforderten Eigenschaften besitzt.The present method also applies ink to the paper, however in a way not previously used: paper fibers are colored with finished ink or ink is produced in such by the well-known double decomposition. These Fibers are sprayed onto a paper web while it is still on the Sieve of the paper machine or behind it. By the pressure of the drying cylinder there is an intimate union of the two types of fiber. It creates a one-sided mottled paper, which has the properties required above.
