Description
Die Erfindung betrifft eine Schneidvorrichtung für Papiere aller Art, insbesondere zum Beschneiden von Lichtpauspapier u. dgl. Es sind bereits Schneidvorrichtungen bekannt, bei denen ein Rundmesser an einem zur Auflage des Papiers bestimmten Tisch entlang geführt wird. Diese bekannten Vorrichtungen waren aber deshalb nachteilig, weil sich das Papier vor und hinter dem Messer aufrollt und dann schlecht zu schneiden ist. Zur Vermeidung dieses Nachteiles ist bereits vorgeschlagen, das zu schneidende Papier an beiden Seiten neben dem Messer zu .erfassen und zu strammen. Hierdurch wird aber ein ordnungsgemäßes Schneiden des vor und hinter dem Messer aufgerollten Papiers nicht ermöglicht. Dies wird auch bei einer weiter bereits bekannten Vorrichtung nicht erreicht, bei der das Papier durch einen einstellbaren Führungskanal zum Schneidmesser geführt und von dort durch eine gekrümmt; Führung weitergeleitet wird. Bei dieser Vorrichtung wird das Papier zwar vor, aber nicht hinter dem Messer geglättet, so daß die Schneidvorrichtung auch nur in einer Richtung verwendet werden kann.The invention relates to a cutting device for papers of all kinds, in particular for trimming blueprint paper and the like known in which a circular knife on a table intended to support the paper is guided along. However, these known devices were disadvantageous because the paper rolls up in front of and behind the knife and is then difficult to cut is. In order to avoid this disadvantage, it has already been proposed that the one to be cut Grasp the paper on both sides next to the knife and tighten it. Through this but is a proper cutting of the rolled up in front of and behind the knife Paper does not allow. This is also the case with a further already known device not reached, in which the paper through an adjustable guide channel to the cutting knife guided and curved from there by one; Leadership is forwarded. At this Device, the paper is smoothed in front of, but not behind the knife, like this that the cutting device can only be used in one direction.
Erfindungsgemäß wird demgegenüber ein einwandfreies Zuschneiden aufgerollter 'Papiere nach beiden Richtungen hin dadurch ermöglicht, daß die Schneidvorrichtung mit vor und hinter dem Messer sitzenden, annähernd gleichgestalteten Armen zum Ausbreiten und Niederhalten des Papiers versehen ist. Vorzugsweise sind die Arme zum Ausbreiten und Niederhalten des Papiers dabei Teile eines nach beiden Seiten über das Messer hinausragenden und an diesen Stellen tütenähnlich aufgerollten Blechkörpers mit ansteigender vorderer Spitze. Der Blechkörper kann dabei insgesamt eine pflugscharähnliche Gestalt haben.According to the invention, on the other hand, perfect cutting is rolled up 'Paper in both directions is made possible by the fact that the cutting device with almost identical arms sitting in front of and behind the knife to spread out and holding down the paper is provided. Preferably the arms are spreadable and holding down the paper while doing parts one on both sides over the knife protruding sheet metal body rolled up like a bag at these points rising front tip. The sheet metal body can overall be similar to a ploughshare Have shape.
Die Erfindung ist in der Zeichnung in einem Ausführungsbeispiel dargestellt, und zwar zeigt Abb. i eine Stirnansicht der Schneidvorrichtung nebst Seitenansicht der Vorrichtung zum Niederhalten des Papiers und Abb. 2 eine Seitenansicht der Schneidvorrichtung nebst Niederhaltevorrichtung. Die Schneidvorrichtung besteht aus einem Tisch i und einem entlang demselben verfahrbaren Schlitten oder Gestell 2, in welchem das als Rundmesser ausgebildete Messer 3 sowie eine Rolle 4. zum Anpressen des Papiers gegen den Tisch i drehbar gelagert sind. Außerdem ist an diesem Schlitten die Niederhaltevorrichtung 5 lösbar angeordnet. Sie besteht, wie die Zeichnung erkennen läßt, aus einem Blech, das nach beiden Seiten über das Rundmesser 3 hinausragt und dessen überstehenden Teile tütenähnlich hochgebogen oder gerollt sind, so daß zwei seitliche Leitflächen oder Arme 6, 7 mit ansteigenden Enden 8 entstehen. Bei einer derartigen Ausführung ist es gleichgültig, in welcher Richtung die Schneidbewegung erfolgt, da entweder der eine Arm 6 oder der andere Arm 7 den vor dem Messer 3 liegenden Teil des Papiers 9 auf den Tisch i drückt. Dadurch ist die Gewähr gegeben, daß unmittelbar vor dem Messer kein gerolltes Papier ist, sondern entrolltes und infolgedessen ein einwandfreier Schnitt erfolgen kann.The invention is shown in the drawing in an exemplary embodiment, namely Fig. i shows a front view of the cutting device together with a side view of the device for holding down the paper and Fig. 2 is a side view of the cutting device together with hold-down device. The cutting device consists of a table i and one along the same movable carriage or frame 2, in which the as Round knife trained knife 3 and a roller 4. for pressing the paper against the table i are rotatably mounted. In addition, the hold-down device is on this slide 5 arranged releasably. As the drawing shows, it consists of a sheet of metal, which protrudes on both sides over the circular knife 3 and its protruding Parts are bent or rolled up like a bag, so that two lateral guide surfaces or arms 6, 7 with rising ends 8 arise. With such an implementation it does not matter in which direction the cutting movement takes place, as either one arm 6 or the other arm 7 the part of the paper lying in front of the knife 3 9 presses on the table i. This guarantees that immediately before Knife is not a rolled paper, but an unrolled one and consequently a flawless one Cut can be made.
