Patentiert im Deutschen Reiche vom 20. Februar 1908 ab.Patented in the German Empire on February 20, 1908.
Die Erfindung bezieht sich auf Kopiermaschinen, die mit durchlaufender, stellenweise geschwächter Papierbahn arbeiten, und besteht in der Anwendung einer bei Druckmaschinen bereits bekannten Einrichtung, die Schwächung der Papierbahn an den späteren Trennstellen in der Maschine selbst, also beim Verarbeiten der Papierbahn, vorzunehmen, so daß letztere in ungeschwächtem Zustande in die MaschineThe invention relates to copier machines with continuous, locally weakened paper web work, and consists in the application of one to printing machines already known device, the weakening of the paper web at the later separation points in the machine itself, so when processing the paper web to make, so that the latter into the machine in a non-weakened state
ίο einlaufen kann. Es läßt sich mithin jedes Rollenpapier benutzen, und es ist nicht notwendig, das Papier für diese Maschine besonders vorzubereiten.ίο can run in. So it can be anything Use roll paper, and it is not necessary to use the paper specifically for this machine prepare.
Das Schwächen der Trennstellen kann dicht vor dem Abtrennen vorgenommen werden, also nachdem das Kopieren bereits erfolgt ist. Soweit wie das Papier sich zwischen den Anfeuchtvorrichtungen und Kopierwalzen befindet, braucht es also keine geschwächten Stellen zu haben, so daß das unbeabsichtigte Zerreißen des Papiers an den schwachen Stellen während des Kopiervorganges vermieden wird.The weakening of the separation points can be carried out just before separation, that is, after copying has already taken place. As far as the paper is between the moistening devices and copier rollers is located, so it does not need to have any weakened areas so that it can be unintentionally torn of the paper at the weak points during the copying process is avoided.
Die Erzeugung der geschwächten Stellen läßt sich in sehr verschiedenartiger Weise vornehmen. Beispielsweise kann ein gezahntes Messer in das durch eine Unterlage mit Rille gestützte Papier eingestoßen werden, , so daß die Zähne Querlochungen erzeugen. Die Schwächung des Papiers kann auch zwischen zwei Walzen erfolgen, indem die aus einer Walze etwas herausragende Klinge in eine an der anderen Walze befindliche Rille eintritt. The weakened areas can be produced in very different ways. For example, a serrated knife can be pushed into the paper supported by a base with a groove, so that the teeth produce transverse perforations. The weakening of the paper can also take place between two rollers, in that the one from one Roller slightly protruding blade enters a groove on the other roller.
