KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
In jeder Papierbahn treten Unregelmäfsigkeiten bezw. Verschiedenheiten auf, infolge deren die Wasserzeichen auf der einen Papierbahn nicht mit den auf einer anderen übereinstimmen. Es war daher nur möglich, nur von einer einzigen mit Wasserzeichen versehenen Papierbahn genau übereinstimmende Bogen abzuschneiden. Es ist jedoch, beispielsweise für Schreibpapier, erforderlich, dafs das Wasserzeichen an jedem Bogen sich in der richtigen Lage befindet. Nach vorliegender Erfindung können nun zwei oder mehr Papierbahnen gleichzeitig geschnitten werden.Irregularities occur in every paper web. Differences on, as a result whose watermarks on one paper web do not match those on another. It was therefore only possible to get watermarked from just a single one Cut off exactly matching sheets of paper. However, it is, for example for writing paper, it is necessary that the watermark on each sheet is in the right location. According to the present invention, two or more paper webs can now be cut at the same time.
Nach vorliegender Erfindung wird jede Papierbahn für sich durch je ein Paar von einander getrennten Zufuhrrollen geleitet, von denen jedes Paar durch einen eigenen besonderen Riementrieb angetrieben wird. Beim Schneiden von beispielsweise zwei Papierbahnen zu gleicher Zeit wird das eine Paar der Zuführrollen mit Hülfe einer ausdehnbaren Riemscheibe oder einer gleichwerthigen Vorrichtung angetrieben, so dafs der die Maschine Bedienende beim Zerschneiden der beiden Papierbahnen die ausdehnbare Riemscheibe in ihrer Gröfse einstellen kann, um die Zuführgeschwindigkeit des Papiers vergröfsern oder verkleinern zu können und die Wasserzeichen auf den beiden Papierbahnen in genaue oder möglichst genaue Uebereinstirnmung zu bringen, bevor sie das Abschneidmesser erreichen. Die gebräuchliche ausdehnbare Riemscheibe in Verbindung mit dem Messer wird dabei nach vorliegender Anordnung beibehalten.According to the present invention, each paper web is for itself by a pair of separate feed rolls, each pair of which is guided by its own special Belt drive is driven. When cutting, for example, two paper webs at the same time, one pair of feed rollers becomes with the aid of an expandable pulley or an equivalent device, so that the operator of the machine When cutting the two paper webs, the size of the expandable pulley can be adjusted to the feed speed of the paper to be able to enlarge or reduce the size and the watermarks on the to bring both paper webs into exact or as exact a correspondence as possible before they reach the cutting knife. The common expandable pulley in conjunction with the knife is retained according to the present arrangement.
Auf der beiliegenden Zeichnung veranschaulicht Fig. ι eine nach vorliegender Erfindung ausgeführte Maschine in der Seitenansicht, während Fig. 2 die Antriebsvorrichtung und die ausdehnbare Scheibe für die Zuführrollen B der Fig. ι in der Seitenansicht darstellt.On the accompanying drawing, FIG. 1 illustrates a machine designed according to the present invention in a side view, while FIG. 2 shows the drive device and the expandable disk for the feed rollers B of FIG. 1 in a side view.
Die eine Rolle für die Papierbahn A ist in einem geeigneten Träger α am Rahmen der Maschine gelagert. Die Papierbahn A wird von dieser Rolle durch die für sich getrennt angetriebenen Zuführrollen B in den Trägern b des Maschinenrahmens geführt. Von den Zuführrollen B gelangt die Papierbahn über die Führungsrollen c1 c1 unter der Führungsrolle dl her zu den Scheibenmessern D, welche in Trägern des Rahmens d gelagert sind, um von dort zusammen mit der Papierbahn H zu den kleinen Zuführrollen E zu gelangen, von denen die beiden Papierbahnen A H zusammen zu dem Messer F geführt werden, um durch den Niedergang des sich drehenden oder schwingenden Messers F1 in der Querrichtung zerschnitten zu werden. Die Messer werden dabei in gewöhnlicher Weise durch ein Getriebe F2 angetrieben, und die abgeschnittenen Bogen fallen auf ein endloses Band G. The one roll for the paper web A is stored in a suitable carrier α on the frame of the machine. The paper web A is guided from this roll through the separately driven feed rolls B in the carriers b of the machine frame. From the feed rollers B , the paper web passes over the guide rollers c 1 c 1 under the guide roller d l to the disc knives D, which are mounted in carriers of the frame d , in order to get from there together with the paper web H to the small feed rollers E , of which the two paper webs AH are fed together to the knife F to be cut in the transverse direction by the downward motion of the rotating or swinging knife F 1. The knives are driven in the usual way by a gear F 2 , and the cut sheets fall onto an endless belt G.
Die zweite Papierbahn H wird über die Führungsrollen j durch die getrennt angetriebenen Zuführrollen K geführt, welche genau ■mit den Zuführrollen B für die Papierbahn A The second paper web H is guided over the guide rollers j through the separately driven feed rollers K , which exactly ■ with the feed rollers B for the paper web A
