Description
Die Vorteile der Erfindung Hegen in erster Linie in der mit geringen Mitteln erzielten Möglichkeit der gemeinsamen Verstellung der beiden Kreismesser einer Schneideinheit, wobei von besonderer Bedeutung das Zusammenwirken der Verriegelung mit den Feststellvorrichtungen und mit dem Verstellantrieb ist, wodurch die Gewähr dafür gegeben ist, daß die optimale Einstellung der beiden Kreismesser zueinander, d, h. die gegenseitige Lage der Schneidkanten im Überschneidungsbereich während des Verstell Vorganges unverändert erhalten bleibt.The advantages of the invention lie primarily in the possibility of being achieved with limited resources joint adjustment of the two circular knives of a cutting unit, which is of particular importance the interaction of the lock with the locking devices and with the adjustment drive is, whereby the guarantee is given that the optimal setting of the two circular knives to each other, d, h. the mutual position of the cutting edges in the overlap area during the adjustment process remains unchanged.
Irn folgenden wird der Gegenstand der Erfindung an Hand des mit der Zeichnung schematisch dargestellten Ausführungsbeispiels beschrieben, wobei vor. einer möglichen Vielzahl von Schneideinheiten, die auf der gesamten Arbeitsbreite beliebig verteilt sein können, nur eine Schneideinheit gezeigt wird.The invention will hereinafter become the subject matter of the invention described with reference to the embodiment shown schematically with the drawing, with before. a possible variety of cutting units, which can be distributed as desired over the entire working width only one cutting unit is shown.
Wie die Abbildung erkennen läßt, besteht die Schnoideinheit aus den beiden Kreismessern 1 und 2, zwischen denen die nichtdargestellte Papierbahn hindurchgeführt wird. Die Kreismesser 1 und 2 sind in den Haltern 3 und 4 drehbar gelagert, die ihrerseits auf den Grundplatten 5 und 6 befest:gt sind. Diese Grundplatten 5 und 6 gleiten in Prismenführungen 7 und 8 auf den Traversen 9 und 10, die sich über die gesamte Bahnbreite der Maschine erstrecken. An der Grundplatte S des Kreismesstrs 1 bzw. an dem Halter 4 des Kreismessers 2 sind Rundführungen 11 und 12 sowie Feststellvorrichtungen 13 und 14 angeordnet, wobei die Feststellvorrichtungen durch pneumatische Zylinder IS und 16 betätigt werden. ParaUel zu den Traversen 9 und 10 verlaufende Rundstäbe 17 und 18 werden von den Rundführungen 11 undAs the figure shows, the Schnoid unit consists of the two circular knives 1 and 2, between which the paper web, not shown, is passed. The circular knives 1 and 2 are rotatably mounted in the holders 3 and 4, which in turn fasten on the base plates 5 and 6 : gt. These base plates 5 and 6 slide in prism guides 7 and 8 on the cross members 9 and 10, which extend over the entire width of the machine. Round guides 11 and 12 and locking devices 13 and 14 are arranged on the base plate S of the circular knife 1 or on the holder 4 of the circular knife 2, the locking devices being actuated by pneumatic cylinders IS and 16. Round bars 17 and 18, which run parallel to the traverses 9 and 10, are supported by the round guides 11 and
