KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Sofern bei der Kopiermaschine nach dem Patent 189920 die Abtrennung des durch Querlochungen geschwächten Kopierpapieres durch Walzen erfolgt, die eine größere Umfangsgeschwindigkeit als die Kopierwalzen haben, müssen die Abtrennwalzen von den Kopierwalzen um mehr als die Länge eines Papierfeldes getrennt sein.Provided that the copier according to the patent 189920 is separated by transverse perforations weakened copy paper is made by rollers, which have a greater peripheral speed than the copy rollers, the separation rollers from the copy rollers must be more than the length of a paper field be separated.

Gemäß der vorliegenden Erfindung soll dieAccording to the present invention, the

ίο Baulänge der Auffangvorrichtung. verkürzt werden. Ermöglicht wird dies dadurch, daß die Abtrenn walzen nicht wie bei der Kopiermaschine nach dem Patent 189920 ständig aneinander anliegen und auf das Papier wirken, sondern daß sie, wie es bei Bogenzuführungsvorrichtungen für andere Zwecke an sich schon bekannt ist, nur zeitweilig auf das Papier einwirken. Das kann erfolgen, indem die eine, und zwar zweckmäßig die über dem Papier liegende Abtrennwalze abwechselnd angehoben und auf das Papier niedergelassen wird, so daß nur in der letzteren Lage durch die Walzen eine Spannung in dem Papier erzeugt wird.ίο Overall length of the fall arrester. shortened will. This is made possible by the fact that the separation does not roll as in the copier according to the patent 189920 are constantly in contact with each other and act on the paper, but that, as with sheet feeders, they are used for other purposes per se is already known, only act temporarily on the paper. That can be done by the one, and specifically the separation roller located above the paper is lifted alternately and is lowered onto the paper so that tension is created in the paper by the rollers only in the latter position will.

In der Zeichnung ist ein Ausführungsbeispiel der neuen Einrichtung in einer Seitenansicht dargestellt.In the drawing, an embodiment of the new device is in a side view shown.

Hinter den drei Walzen c, d, β der Kopiermaschine sind die Walzen f und g gelagert, die durch Schnüre k verbunden sind. Auf der Walze g liegt eine Leitwalze h auf, die durch Eigengewicht oder durch Federwirkung auf der Papierbahn s in bekannter Weise lastet. Auf der Achse der Walze g sitzen an den Enden Scheiben ft, die eine Abflachung ft1 haben. Diese fassen unter die Zapfen h1 der Walze h. Die Walze h kommt somit während einer Umdrehung der Walze g einmal auf der Papierbahn und der Walze g zur Auflage, nämlich wenn die Abflachungen ft1 sich unter den Zapfen h1 befinden. In diesem Augenblick wird von der schneller als die Walzen w und f sich drehenden Walze h im Verein mit der die gleiche Umfangsgeschwindigkeit besitzenden Walze g eine kurze kräftige Spannung in der Papierbahn s erzeugt. Diese Spannung zerteilt das Papier, sofern zwischen den Walzenpaaren f, w und g, h eine geschwächte Stelle sich befindet.Behind the three rollers c, d, β of the copying machine, the rollers f and g are mounted, which are connected by cords k . A guide roller h rests on the roller g and bears in a known manner on the paper web s by its own weight or by spring action. On the axis of the roller g, disks ft, which have a flattening ft 1 , are seated at the ends. These grasp under the pin h 1 of the roller h. The roller h thus comes to rest once on the paper web and the roller g during one revolution of the roller g , namely when the flattened areas ft 1 are located under the journals h 1 . At this moment, the roller h, which is rotating faster than rollers w and f , in conjunction with roller g, which has the same peripheral speed, generates a brief, strong tension in the paper web s. This tension divides the paper if there is a weakened point between the roller pairs f, w and g, h.

Zum Abheben der Walze h sind verschiedene Einrichtungen anwendbar. Es kann auch von einem wirklichen Abheben ganz abgesehen werden, wenn man die Walze h oder die Walze g oder beide nicht voll zylindrisch macht, sondern einzelne zylindrische Mantelstreifen von nach dem Walzeninnern zurückspringenden Teilen unterbrechen läßt.Various devices can be used to lift off the roller h. A real lift-off can also be completely refrained from if the roller h or the roller g or both are not made fully cylindrical, but rather individual cylindrical casing strips are interrupted by parts that spring back towards the inside of the roller.
