Description
Schneidemaschine für Papierstapel u. dgl. Beim Schneiden von Papieren, besonders solchen, die leicht sind, zwischen denen sich gewöhnlich viel Luft befindet und die dadurch im Stapel stark aufbauschen, bereitet es oft Schwierigkeiten, ein genaues Format zu erreichen, weil der Stapel unter dem Druck der Pressung stark zusammengedrückt wird und dadurch ein Verschieben der oberen Lagen eintritt. Um diesem Übelstande zu begegnen, ist eine Vorrichtung bekannt, bei welcher einzelne Stäbe, die über die ganze Länge des Hintertisches reichen, sich beim Niedergehen des Preß-Balkens auf den Stapel auflegen und so die gröbsten Wellen ausdem Materialherausdrücken. Diese Einrichtung kann aber im wesentlichen nur den Stapel Blattdrücken, also die Wellen, welche parallel zur Schneidrichtung verlaufen, ausglätten, aber man kann mittels dieser Einrichtung die zwischen den einzelnen Papierlagen befindliche Luft nicht genügend herauspressen, da sich die Stäbe in einzelnen, unveränderlichen Linien auf das Material auflegen.Cutting machine for stacks of paper and the like. When cutting papers, especially those that are light and usually have a lot of air between them and the resulting bulk up in the pile, it often causes difficulties to achieve the exact format because the stack is strong under the pressure of the pressing is compressed and thereby a shifting of the upper layers occurs. Around To meet this disadvantage, a device is known in which individual Bars that extend the entire length of the back table, when going down of the press beam on the stack and thus push the coarsest waves out of the material. However, this device can essentially only press the stack of sheets, so the Smooth out waves that run parallel to the cutting direction, but you can by means of this device, the air located between the individual paper layers Do not press out enough, as the bars are in individual, unchangeable lines place on the material.
Durch die nachstehendbeschriebene Erfindung wird dieser Übelstand beseitigt, indem die Luft aus dem auf dem Schneidemaschinentische aufliegenden Papierstoße bei seiner Bewegung vor dem Schneiden ausgestrichen wird.The invention described below eliminates this inconvenience eliminated by puffing the air out of the paper resting on the cutting machine table is smeared out as it moves before cutting.
In der Abbildung ist die Erfindung in einer beispielsweisen Ausführung in Seitenansicht der Maschine dargestellt. Der zu schneidende Stoß Papier 2 wird zunächst in einer an sich bekannten Klemmvorrichtung 3, die sich am Sattel4des Schneidemaschinentisches$ befindet, und zwar in vorderster Stellung des Sattels q., fest eingespannt, worauf eine Walze 6 oder ein Ausstreichbalken oder. eine ähnliche Vorrichtung, die zwischen dem Sattel und dem Preßbalken a angeordnet ist, auf den Stoß 2 heruntergelassen wird. Dies kann durch einen Fuß- oder Handhebel oder auch maschinell erfolgen. Bei der Rückwärtsbewegung des Sattels q. wird die Klemmvorrichtung 3 und damit der Stoß Papier 2 nach der Hinterseite des Tisches gezogen, wobei die zwischen den einzelnen Lagen des Stoßes 2 befindliche Luft durch die Walze 6 ausgestrichen und ein niedriger, fester und glattliegender Stoß Papier erreicht wird.In the figure, the invention is in an exemplary embodiment shown in side view of the machine. The pile of paper 2 to be cut becomes initially in a known clamping device 3, which is located on the saddle 4 of the cutting machine table $ is, in the foremost position of the saddle q., firmly clamped, whereupon a roller 6 or a spreading bar or. a similar device used between the saddle and the press beam a is arranged, lowered onto the joint 2 will. This can be done using a foot or hand lever or by machine. at the backward movement of the saddle q. becomes the clamping device 3 and thus the joint Paper 2 is pulled towards the back of the table, the between each Layers of the shock 2 located air through the roller 6 and a lower, a firm and smooth pile of paper is achieved.
