Die Erfindung bezieht sich auf eine Untermesserwelle für eine Vorrichtung zum Längsschneiden von laufenden Bahnen, z. B. aus Papier, mit umlaufenden kreisförmigen Obermessern und mindestens einer mit diesen zusammenarbeitenden, aus Schneidringen und zwischen diesen vorgesehenen, mit ihnen fluchtenden Laufflächen bestehenden und von der zu schneidenden Bahn teilweise umschlungenen Gegenwerkzeugwalze. Bei Rollenschneid- und Umrollmaschinen, insbesondere bei solchen, bei denen die Bahn in einer der Maschinenbreite entsprechenden Breite verarbeitet wird, haben die Arbeitsbreiten der Papiermaschinen im Laufe der Zeit erheblich zugenommen. Andererseits werden von Rollenschneid- und Umrollmaschinen immer höhere Laufgeschwindigkeiten verlangt, so daß sich für die in üblicher Weise beiderseits gelagerte Untermesserwelle außerordentlich ungünstige kritische Drehzahlen ergeben, die zu Schäden an der Schneideinrichtung führen können. Dem läßt sich zwar dadurch begegnen, daß der Durchmesser der Untermesserwelle vergrößert wird. Bei den heute vielfach verlangten Arbeitsbreiten und Laufgeschwindigkeiten sind dazu Durchmesser nötig, die die Untermesserwellen sehr stark verteuern und als völlig unwirtschaftlich angesehen werden müssen.The invention relates to a lower cutter shaft for a device for longitudinal cutting of running tracks, e.g. B. made of paper, with circumferential circular upper knives and at least one with these cooperating, from cutting rings and provided between them, aligned with them Existing running surfaces and partially wrapped by the web to be cut counter-tool roller. In roll cutting and rewinding machines, especially those in which the web is in one the width corresponding to the machine width is processed, have the working widths of the paper machines increased significantly over time. On the other hand, winder and rewinding machines are used Always higher running speeds required, so that in the usual way on both sides Bearing lower cutter shaft result in extremely unfavorable critical speeds that lead to damage can lead to the cutting device. This can be countered by the fact that the diameter the lower knife shaft is enlarged. With the working widths and running speeds that are often demanded today are necessary for this diameter, which make the lower cutter shafts very expensive and as must be viewed as completely uneconomical.
Es ist zwar schon bekanntgeworden, die Untermesserwellen in solchen Fällen an mehreren Stellen durch Zwischenlager zu unterstützen. Bei solchen Maschinen, bei denen die Bahn in einer Ebene durch die Schneideinrichtung läuft, ist das ohne weiteres möglich. Viele Materialien lassen sich aber nur dann exakt schneiden, wenn sie vor und hinter der Schneidstelle die Untermesserwelle auf einem bestimmten Winkel umschlingen. Bei solchen Ausführungen, bei denen die mit den Obermessern zusammenarbeitende Untermesserwalze aus Schneidringen und zwischen diesen vorgesehenen, mit ihnen fluchtenden Laufflächen für die Bahn bestehen, ist eine Zwischenlagerung der Untermesserwelle nur sehr schwer anzubringen. Bisherige Vorschläge dieser Art konnten nicht befriedigen.It has already become known that the lower cutter shafts in such cases in several places to be supported by interim storage. In such machines where the path is in one plane the cutting device is running, this is easily possible. Many materials can only be used then cut exactly if they place the lower cutter shaft on a certain in front of and behind the cutting point Wrap around an angle. In such designs, in which the one working with the upper knives Lower knife roller made of cutting rings and running surfaces provided between them and aligned with them exist for the web, intermediate storage of the lower cutter shaft is very difficult to install. Previous proposals of this kind have not been satisfactory.
Der Erfindung liegt die Aufgabe zugrunde, Längsschneidemaschinen so auszubilden, daß Bahnen beliebiger Arbeitsbreiten geschnitten werden können.The invention is based on the object of designing longitudinal cutting machines so that any webs Working widths can be cut.
Durch die Erfindung werden bei derartigen Längsschneidvorrichtungen mit teilweise umschlungener
Untermesserwalze die erwähnten Nachteile vermieden und die kritischen Drehzahlen dadurch aus dem Bereich
der Arbeitsdrehzahlen gebracht, daß die Untermesserwelle in mehrere, die Untermesser tragende
kürzere Untermesserwellen aufgeteilt ist, die in zwei zueinander parallelen Achsen gegeneinander versetzt
Untermesserwelle für eine Vorrichtung zum
Längsschneiden von BahnenThe invention avoids the above-mentioned disadvantages in such longitudinal cutting devices with partially wrapped lower cutter rollers and the critical speeds are brought out of the range of working speeds by dividing the lower cutter shaft into several shorter lower cutter shafts carrying the lower cutter, the lower cutter shaft offset from one another in two mutually parallel axes for a device for
Longitudinal cutting of webs

angeordnet sind. Es ist zwar an sich bei Längsschneidvorrichtungen bekannt, die Gegenwerkzeuge auf zwei parallelen Achsen und versetzt zueinander anzuordnen, jedoch handelt es sich hier nicht um die Aufteilung einer Untermesserwelle in mehrere kürzere Untermesserwellen und um die Lösung der Aufgabe, das Auftreten kritischer Drehzahlen bei großen Arbeitsbreiten zu verhindern.are arranged. Although it is known per se in longitudinal cutting devices, the counter tools on two parallel axes and offset to each other, but this is not about the division a bottom knife shaft into several shorter bottom knife shafts and to solve the task, to prevent the occurrence of critical speeds with large working widths.
In weiterer Ausbildung des Erfindungsgedankens ist es zweckmäßig, wenn die über den nicht mit Untermessern besetzten Teilen beider Achsen angeordneten Laufflächen für die Bahn teilweise aus feststehenden, kreisförmig gebogenen Lagerkörpern od. dgl. und teilweise aus damit fluchtenden, in den Achsen der Untermesser drehbar gelagerten Walzen gebildet sind. In der Zeichnung sind einige Ausführungsmöglichkeiten der Erfindung schematisch dargestellt.In a further development of the inventive concept, it is useful if the over the not with lower blades occupied parts of both axles arranged running surfaces for the track partly from fixed, circularly curved bearing bodies od. Like. And partially aligned therewith, in the axes of the Lower knife rotatably mounted rollers are formed. In the drawing are some possible designs of the invention shown schematically.

Die Bahn 1 läuft in Pfeilrichtung der Schneideinrichtung zu, die auf dem Gestell 2 gelagert ist. Hinter der Schneideinrichtung wird die Bahn über eine Walze 3 weitergeführt. Mit 4 und 5 sind die kreisförmigen Obermesser bezeichnet, die in die Nuten der Untermesser eingreifen und in Armen 6 bzw. 7 gelagert sind. Diese Arme sind in bekannter Weise auf der Welle 8 verschieb-, schwenk- und feststellbar und können dadurch an der vorgesehenen Schneidstelle in die in Betracht kommende Nut des Untermessers eingeführt und gegen dessen Schneidkante gepreßt werden.The web 1 runs in the direction of the arrow to the cutting device, which is mounted on the frame 2. Behind the cutting device, the web is continued over a roller 3. 4 and 5 denote the circular upper cutters which engage in the grooves of the lower cutters and are mounted in arms 6 and 7, respectively. These arms can be displaced, pivoted and locked in a known manner on the shaft 8 and can thereby be inserted at the intended cutting point into the groove of the lower knife which is to be considered and pressed against its cutting edge.
An Stelle einer durchgehenden Untermesserwelle sind mehrere kürzere Untermesser 9,10 und 11 vorhanden, die in gleicher Weise wie eine übliche Untermesserwelle ausgebildet sind. Die einzelnen Untermesser überdecken sich etwas in Richtung der Bahn-Instead of a continuous lower cutter shaft, there are several shorter lower cutters 9, 10 and 11, which are designed in the same way as a conventional lower cutter shaft. The individual lower knives overlap somewhat in the direction of the
