Description

Federnd gelagertes Kreismesser für Längsschneider. Die Erfindung bezieht sich auf ein federnd gelagertes Kreismesser zum Schneiden schmaler Längsstreifen aus laufenden Papierbahnen, bei denen der Federstützring zugleich Träger für das nebenanliegende Messer ist, und besteht darin, daß statt der zum Ring endlos geschlossenen Schraubenfeder eine ringförmige Blattfeder verwendet ist. Eine solche Blattfeder, die als Zungenplatte ausgebildet sein kann, beansprucht wesentlich weniger Raum als die bekannte Schraubenfeder und kann sich auch nicht, nachdem sie als Ganzes den Messerzylinder umschließt, loslösen und die übrigen Messer gefährden.Spring-mounted circular knife for slitter. The invention relates on a spring-mounted circular knife for cutting narrow longitudinal strips from running paper webs, in which the spring support ring is also a carrier for the adjacent knife is, and consists in that instead of the endlessly closed to the ring Helical spring an annular leaf spring is used. Such a leaf spring which can be designed as a tongue plate, takes up much less space than the well-known coil spring and can also not after it as a whole encloses the knife cylinder, loosen it and endanger the other knives.

Das wesentliche Merkmal der neuen Blattfeder beruht darauf, daß der kegelige oder keilartige Ringbund fortfällt, der bei allen Federandrückvorrichtungen mit geschlossener Xreisschraubenfeder unbedingt erforderlich ist, um die Feder auswirken zu lassen. Dieser Fortfall des Ringbundes aber ermöglicht die für den Feinschnitt hochwichtige Raumersparnis, durch die allein die Erhöhung der Schnittfeinheit erzielt werden kann. Da die Blattfeder auf ihrem Sitz sich nicht wie die Schraubenfeder verschieben kann, ist die Anpressung an allen Punkten eine dauernd gleichbleibende und gleichmäßige.The main feature of the new leaf spring is based on the fact that the conical or wedge-like collar is omitted, which is the case with all spring pressure devices with closed xreis coil spring is absolutely necessary to affect the spring allow. This omission of the ring collar enables the fine cut extremely important space saving, through which alone the increase in the fineness of the cut is achieved can be. Because the leaf spring on its seat is not like the coil spring can shift, the pressure at all points is constant and even.

Die Fig. r bis q. der Zeichnungen stellen eine Ausführungsform der Erfindung dar, und zwar zeigen Fig. rund 2 ein zusammengestelltes Messer, und Fig. 3 und q. eine Zungenfeder.Figures r to q. of the drawings illustrate an embodiment of the Invention, namely Fig. 2 show an assembled knife, and Fig. 3 and q. a tongue spring.

Das Messer m wird von dem Stützring s getragen, wobei die Zungenfeder k die federnde Anpressung bewirkt. Die Blattfeder k kann die in den Fig. 3 und q. gezeichnete Ausführung haben.The knife m is carried by the support ring s, with the tongue spring k causes the resilient pressure. The leaf spring k can be shown in FIGS. 3 and q. have drawn execution.

Die auf die Messerwelle aufgeschobenen bekannten Stützringe (Muffen) haben den Zweck, eine genaue Teilung der Messer m zu gewährleisten, und die neue Blattfeder hat den Zweck, das Messer gegen seinen Stützring federnd anzupressen.The well-known support rings (sleeves) pushed onto the knife shaft have the purpose of ensuring an accurate division of the knife m, and the new The purpose of the leaf spring is to press the knife resiliently against its support ring.

Die Feder braucht nicht unbedingt mit auf dem -Stützring zu sitzen, sondern kann auch zwischen den Stützringen auf der Welle sitzen, da sie als Blattfeder außerordentlich dünn sein kann.The spring does not necessarily have to sit on the support ring, but can also sit between the support rings on the shaft, since it acts as a leaf spring can be extremely thin.
