Falzzylinder an Rotationsdruckmaschinen, welche Falze dadurch herstellen, daß in dem einen Zylinder ein einige Millimeter vorstehendes Messer das zwischen beiden Zylindern hindurchlaufende Papier in eine Nut des;anderen Zylinders eindrückt, in der sich eine Klappe schließt, sobald das Messer das Papier hineingedrückt hat, sind bekannt. Bekannt sind Falzmesser, welche feststehend, federndFolding cylinder on rotary printing machines, which produce folds in that in the a cylinder a knife protruding a few millimeters that between the two cylinders passing paper into a groove of the; other cylinder, in which there is a The flap closes as soon as the knife has pushed the paper in, are known. Known are folding knives, which are fixed, resilient
ίο und schwingend angeordnet sind. Ebenfalls sind bekannt Klappen, welche eine feste Schiene und schwingende Gegenschiene besitzen, oder auch solche Falzklappen, bei denen beide Schienen schwingen. Bei diesen bekannten. Falzmechanismen ist es häufig nicht zu vermeiden, daß das Papier von dem aus der Klappe zurückgehenden Messer herausgezogen wird. Man hat diesem Übelstand dadurch abzuhelfen gesucht, daß man die Klappe oder die feste Gegenschiene geriffelt oder mit Leder oder Gummi bekleidet hat. Wegen der starken Abnutzung dieser weichen Materialien und des unvermeidlichen Abschmierens des Druckes, wenn man in diesen hineinfalzt, sind diese Hilfsmittel nur Notbehelfe.ίο and are arranged swinging. Likewise are known flaps that have a fixed rail and a swinging counter rail, or also those folding jaws in which both rails vibrate. With these well-known. Folding mechanisms, it is often unavoidable that the paper is pulled out by the knife returning from the flap will. One has tried to remedy this problem by corrugating the flap or the fixed counter rail or with Dressed in leather or rubber. Because of the heavy wear and tear on these soft materials and the inevitable smearing of the print when you fold into it, these aids are only makeshifts.
Die nachstehend beschriebene Erfindung gibt ein Mittel an die Hand, den Bogen an einzelnen Stellen sicher festzuhalten, ohne daß das zurückweichende Falzmesser den Bogen wieder aus der Klappe herausziehen kann.The invention described below provides a means at hand, the bow individual points to be held securely without the retracting folding knife hitting the sheet can pull it out of the flap again.
Die Falzzylinder α und b sind auf der Zeichnung in Fig. 4 und 5 nur angedeutet und der Deutlichkeit halber auseinandergerückt. Die Klappenwelle c hält nur mit den an den Daumen d angebrachten Erhöhungen e die nicht gezeichneten Bogen fest, während der übrige Teil des Bogens durch mäßigen Druck einer federnden oder auch starren Schiene f (Fig. 7) gefalzt und festgehalten wird. Das Falzmesser g besitzt an den den Erhöhungen e entsprechenden Stellen Unterbrechungen h, wodurch die Erhöhungen e das Papier direkt gegen die feste Schiene i (Fig. 6) drücken, ohne das Messer zu fassen und an dem Zurücktreten zu hindern. Statt der zwei Erhöhungen e können auch mehrere oder nur eine angeordnet werden, welche auch ebensogut an der Schiene i angebracht werden können oder auch an den Daumen d und an der Schiene.The folding cylinders α and b are only indicated in the drawing in FIGS. 4 and 5 and are moved apart for the sake of clarity. The flap shaft c holds only the d attached to the thumb increases e the not-drawn sheet fixed while the remaining part of the sheet F by moderate pressure of a resilient or rigid rail (Fig. 7) is folded and held. The folding knife g has interruptions h at the points corresponding to the elevations e , as a result of which the elevations e press the paper directly against the fixed rail i (FIG. 6) without grasping the knife and preventing it from stepping back. Instead of the two elevations e , several or only one can be arranged, which can just as well be attached to the rail i or also to the thumb d and to the rail.
