KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Nach dem Haupt-Patent 132945 sowie nach dem ersten Zusatz-Patent 1 33825 in das Schneidmesser fest im Maschinengestell gelagert, wobei zu den Seiten des Messers federnde Platten angeordnet sind, die durch den zweitheiligen oder geschlitzten beweglichen Schneidbalken niedergedrückt werden, nachdem das Papier zwischen der unteren Fläche des Schneidbalkens und den federnden Platten straffgespannt ist. Das straffgespannte Papier wird dabei über das feststehende Messer gedrückt und dabei zertheilt.According to the main patent 132945 and according to the first additional patent 1 33825 in the cutting knife Fixed in the machine frame, with resilient plates arranged on the sides of the knife depressed by the two-part or slotted movable cutter bar after the paper is between the lower surface of the cutter bar and the resilient plates is taut. The taut paper is thereby over the stationary Knife pressed and divided in the process.
In der Ruhelage ragen die federnden Platten etwas über die Messerschneide empor, so dafs beim Weiterziehen des Papierstreifens, um ein neues Blatt abzuschneiden, das Messer von dem quer über dasselbe hinwegbewegten Papier nicht berührt wird.In the rest position the resilient plates protrude a little above the knife edge, so that when pulling the strip of paper to cut a new sheet, the knife from the across the same piece of paper that is being moved.
Hierbei ergiebt sich, die Gefahr, dafs die Federn, welche die zu den Seiten des Messers angeordneten Platten tragen, ihre ursprüngliche Spannkraft bald verlieren, da ihre Elasticität infolge der ständigen Belastung durch die Platten und durch das immerfort wiederholte Zusammendrücken in verhältnifsmäfsig kurzer Zeit zerstört wird. Infolge dessen nehmen die federnden Platten allmählich eine tiefere Lage .an, so dafs die Messerschneide aus ihnen hervortritt und nun durch den weiter gezogenen Papierstreifen berührt und dadurch schnell stumpf wird.Here there is the danger that the springs, which are arranged on the sides of the knife Plates wear, soon lose their original elasticity because of their elasticity as a result of the constant load from the plates and from the repetitive Compression is destroyed in a relatively short time. As a result, the The springy plates gradually move to a deeper position, so that the knife edge protrudes from them and now touched by the further drawn paper strip and quickly becomes dull.
Nach vorliegender Erfindung soll, um dies zu verhüten, die Anordnung getroffen werden, dafs der Schneidbalken im Maschinengestell gelagert wird, während das Schneidmesser und mit ihm die federnden Platten über den Schneidbalken bewegt werden. Bei solcher Anordnung erfahren die Federn für die elastische Lagerung der Platten durch deren Gewicht keine ständige Belastung, und wenn die Federn schwach werden sollten, so kann doch, da das Messer bei einem Vorziehen des Papierstreifens hochsteht, dasselbe von dem Papier keineswegs berührt werden, zumal die Platten, schon durch ihr Eigengewicht veranlafst, sich stets über die Kante des Messers hinausbewegen werden.According to the present invention, in order to prevent this, the arrangement should be made that the cutting bar is stored in the machine frame, while the cutting knife and with it the resilient plates can be moved over the cutter bar. With such an arrangement, the springs experience for the elastic Storage of the panels by their weight does not have a permanent load, and when the springs should become weak, it can, as the knife is when the paper strip is pulled out it is in no way touched by the paper, especially since the plates are already through their own weight causes them to always move over the edge of the knife.
Das Messer mit seinen federnden Platten kann dabei entweder fest an einem Bügel angeordnet oder es kann mit demselben beweglich verbunden sein. Es ist dabei auch möglich, den im Gestell ruhenden Schneidbalken, das ist das Widerlager für die federnden Platten, beweglich zu lagern. Unter Umständen können dabei auch noch die unteren Platten oder der Schneidbalken von Federn getragen werden.The knife with its resilient plates can either be fixed to a bracket or it can be movably connected to it. It is also possible to use the cutting bar resting in the frame, this is the abutment for the resilient plates to be movably supported. May be the lower plates or the cutter bar are also supported by springs.
Ein Ausführungsbeispiel der abgeänderten Einrichtung ist auf der Zeichnung dargestellt.An embodiment of the modified device is shown in the drawing.

und durch den Bolzen q mit dem Bügel ρ beweglich verbunden. Unter der Platte t ist das Messer i befestigt; zu den Seiten des Messers sind die federnden Platten c angeordnet, die ebenfalls winkelförmigen Querschnitt haben und deren Seitenschenkel cl mit Abbiegungen c1 zur Begrenzung ihrer Bewegung nach unten versehen sind. Stifte d mit Federn f bewirken die elastische Lagerung der Schienen und Platten c. Fest im Gestell ist der mit Eintrittsschlitz für das Messer versehene Schneidbalken k gelagert.and movably connected to the bracket ρ by the bolt q. The knife i is fastened under the plate t; on the sides of the knife, the resilient plates c are arranged, which also have an angular cross-section and whose side legs c l are provided with bends c 1 to limit their downward movement. Pins d with springs f cause the rails and plates c to be supported elastically. The cutter bar k, which is provided with an entry slot for the knife, is mounted firmly in the frame.
Befindet sich der Bügel ρ in der Hochstellung, so wird das zu schneidende Papier in die richtige Lage über dem Schneidbalken gebracht. Wird dann der Bügel ρ niederbewegt, so legen sich die nach unten über die Messerkante vortretenden Platten c zunächst auf den Messerbalken k auf und spannen das Papier straff über den Schlitz des Balkens. Dann tritt bei dem weiteren Abwärtsbewegen das Messer durch das straffgespannte Papier hindurch und zertheilt dieses.If the bracket ρ is in the upper position, the paper to be cut is brought into the correct position above the cutter bar. If the bracket ρ is then moved down, the plates c protruding downwards over the knife edge first lie on the knife bar k and stretch the paper tightly over the slot in the bar. Then, as it moves further downwards, the knife passes through the taut paper and cuts it.
