  Verstellbarer Doppelfalztrichter für   Rotation8druckmaschlnen.   



   Es sind bereits Falzvorrichtungen bekannt geworden, bei denen zwei Falztrichter nebeneinander und gegeneinander einstellbar angeordnet sind, um die Falzvorrichtung für verschiedene Papierbreiten verwenden zu können (z. B.   amerik.   Patentschrift Nr. 518242). 



  Bei diesen Falzvorrichtungen war die Verstellung der beiden Falztrichter nur innerhalb enger Grenzen   nnd   in umständlicher Weise durchführbar. Diese   (Jbelstände   werden bei der vorliegenden Erfindung dadurch vermieden, dass die beiden Falztrichter an den einander zugekehrten Seiten mit rechenartig ineinandergreifenden Einschnitten und Vorsprüngen versehen sind, so dass sie der jeweiligen Papierbreite entsprechend ineinander verschoben werden können. 



   Ein Ausführungsbeispiel der Erfindung ist in der schematischen Zeichnung veranschaulich. a und b sind die beiden sogenannten Falztriebter, deren einander zugekehrte Seiten mit Aussparungen c, d versehen sind, so dass die rechenartigen Vorsprünge e, f bei Annäherung in jene Aussparungen c, d hineingelangen. 



   Die beiden Fig. 1 und 2 zeigen die Falztrichter mit den zugehörigen Walzen in den verschiedenen Stellungen, und zwar Fig. 1 in der Einstellung für eine breite Papierrolle, Fig. 2 für eine schmale Papierrolle. Von einem breiten Strang, der in der Mitte der Längsrichtung geteilt wird, werden die beiden Hälften je über einen kleinen Trichter auf je einen Falzapparat geführt. 



   Jeder der beiden Falztrichter steht in fester Verbindung mit dem dazugehörigen Falzapparat. Wird eine Veränderung in der Papierrolle vorgenommen, so müssen beide Falzapparate so eingestellt werden, dass die Trichterspitze und die Mittellinien genau in der Mitte der linken und rechten halben Papierbahn zu stehen kommen. Es findet dabei eine Ineinanderschiebung der beiden Trichterhälften statt. Da die beiden Trichter in einer Ebene liegen und genau symmetrisch angeordnet sind, so wird nur ein Paar gemeinsamer Zuführungswalzen gebraucht.

  Adjustable double former for rotary printing presses.



   Folding devices are already known in which two folding formers are arranged next to one another and can be adjusted against one another in order to be able to use the folding device for different paper widths (e.g. American Patent No. 518242).



  With these folding devices the adjustment of the two fold formers could only be carried out within narrow limits and in a laborious manner. In the present invention, this is avoided by providing the two fold formers with rake-like interlocking incisions and projections on the sides facing one another, so that they can be shifted one inside the other according to the respective paper width.



   An embodiment of the invention is illustrated in the schematic drawing. a and b are the two so-called folding drives whose sides facing each other are provided with recesses c, d so that the rake-like projections e, f enter those recesses c, d when they approach.



   The two FIGS. 1 and 2 show the fold formers with the associated rollers in the various positions, namely FIG. 1 in the setting for a wide paper roll, FIG. 2 for a narrow paper roll. From a wide strand that is divided in the middle of the longitudinal direction, the two halves are each fed via a small funnel onto a folder each.



   Each of the two formers is permanently connected to the associated folder. If a change is made in the paper roll, both folders must be set so that the tip of the funnel and the center lines are exactly in the middle of the left and right half of the paper web. The two funnel halves are pushed into one another. Since the two hoppers lie in one plane and are arranged exactly symmetrically, only one pair of common feed rollers is required.
