Description

Perforierwerkzeug zum Lochen von Papierblocks großer Stärke Während es bisher nur möglich war, dünne Lagen von Papier (etwa 2o Blatt) einwandfrei zu perforieren, kann man nach der Erfindung ganze Blocks von beliebiger Stärke auf einmal perforieren, ohne befürchten zu müssen, daß die unteren Blätter zerrissen werden. Bei den jetzt im Gebrauch -befindlichen Perforierwerkzeugen wurde das Papier zwischen eine Führungsleiste und die Matrize eingeführt, dann wurden die Perforierstifte- heruntergedrückt, die dabei durch das Papier drangen und die ausgestanzten Papierpfropfen durch die Matrize stießen. Nimmt man aber stärkere Lagen Papier und versucht diese zu perforieren, so ergibt sich folgendes Bild: Die Stifte dringen durch die oberen Blätter, stanzen diese sauber und schieben die ausgestanzten Papierpfropfen vor sich her. Da nun die Größe der Pfropfen beim Weitergang der Stifte nach unten dau-.ernd :anwächst, setzen die Pfropfen dem Werkzeug einen wachsenden Widerstand entgegen. Sie vermögen selbst schließlich das Papier nicht zu durchbohren, weichen nach der Seite aus und zerreißen dabei die unteren Blätter.Perforating tool for punching thick paper blocks during up to now it has only been possible to produce thin layers of paper (about 20 sheets) perfectly perforate, you can according to the invention whole blocks of any thickness perforate once without fear of tearing the lower sheets will. With the perforating tools now in use, the paper was inserted between a guide bar and the die, then the perforating pins were pressed down, which penetrated through the paper and the punched out paper plugs pushed through the die. But if you take thicker layers of paper and try them To perforate, the following picture emerges: The pins penetrate through the upper ones Sheets, punch them cleanly and push the punched-out paper plugs forward here. Since now the size of the plug as the pins continue downwards : grows, the plugs oppose the tool with increasing resistance. After all, they are unable to pierce the paper themselves, so give way to the Page out, tearing the lower sheets.

Diesem Übelstand kann man durch das neue Perforierwerkzeug abhelfen. Dies besteht wie früher aus Deckleiste i, Nadelleiste z, Perforiernadeln 3 sowie Führungsleiste ¢, aber an Stelle einer Matrize aus mehreren, 5. Die Blätter des zu lochenden Blockes werden nun durch 'die übereinanderliegenden Matrizen unterteilt eingeführt und dann die Perforation vorgenommen. Durch diese Maßnahme wird eine einwandfreie Durchl.ochung erreicht, auch wesentliche Arbeitszeit erspart. Ferner kann es nicht vorkommen, daß einzelne. Blätter in geblockter Form, wie dies bei der jetzt üblichen Art der lagenweisen Perforation vorkommt, beim Arbeiten überschlagen werden und unperforiertbleiben. Schließlich besteht die Möglichkeit, seinen Block dicht am Heftrücken. zu perforieren.This problem can be remedied with the new perforating tool. As before, this consists of cover strip i, pin strip z, perforating needles 3 and also Guide bar ¢, but instead of a die made of several, 5. The sheets of the The blocks to be punched are now subdivided by 'the overlapping matrices inserted and then made the perforation. This measure becomes a Perfect perforation achieved, also saves considerable working time. Further it cannot happen that individual. Leaves in a blocked form, like this at the type of layer-by-layer perforation that is now common, overturn it when working and remain imperforate. Finally there is the option of his block close to the spine. to perforate.

Die Anwendung dieser vorbeschriebenen Blockperforation' ist besonders für Banken, Kassen und Kaufhäuser von Bedeutung.The application of this block perforation described above is special of importance for banks, cash registers and department stores.
