Description

Die Erfindung stellt eine Vorrichtung dar mit dem Zweck, Spinn- und sonstige Papiere in Streifen zu schneiden.The invention represents a device with the purpose of spinning and other papers cut into strips.

In der Zeichnung ist die Vorrichtung in Fig. ι und 2 in einem Längsschnitt und in einer Stirnansicht dargestellt. Fig. 3, 4 und 5 zeigen Einzelheiten.In the drawing the device is in Fig. Ι and 2 shown in a longitudinal section and in a front view. Figures 3, 4 and 5 show details.

iö Anliegen der einzelnen Kreismesser an die Gegenmesser eine Messerwelle in der Achsenrichtung verschoben wird, wodurch die einzelnen Messer gegeneinander gedrückt werden. Bei diesen Schneidemaschinen müssen die einzelnen Messer eine gewisse Stärke haben, um diesen Anpressungsdruck aufnehmen zu können, weshalb auch die zu schneidenden Papierstreifen nicht beliebig schmal geschnitten werden können. Durch den längsachsigen Anpressungsdruck ist aber ein dauerndes Anliegen sämtlicher Messer wegen der eintretenden· Wärmeausdehnung' kaum möglich. Einzelne Messer erhalten einen zu hohen Anpressungsdruck, andere liegen überhaupt nicht an.iö contact of the individual circular knives on the counter knife a knife shaft in the axial direction is moved, whereby the individual knives are pressed against each other. at In these cutting machines, the individual knives must have a certain strength in order to be able to do this To be able to absorb contact pressure, which is why also the paper strips to be cut cannot be cut as narrow as desired. Due to the longitudinal contact pressure but is a constant concern of all knives because of the occurring 'thermal expansion' hardly possible. Individual knives are subjected to excessive pressure, others are not applied at all.

Die Neuerung besteht darin, daß die-Kreismesser und ihre Gegenmesser Kegelflächen haben, welche derart auf einander wirken, daß beim Verschieben der Messerachsen senkrecht gegeneinander, diese Kegelflächen aufeinander gleiten und hierdurch die Schneidkanten der umlaufenden Kreismesser mit den Schneidkanten der Gegenmesser zum Anliegen kommen. Bei dieser Anordnung werden die Kreismesser nicht auf Biegung beansprucht wie bei bekannten Einrichtungen, wo die Anpressungskraft in der Mitte der Messer angreift, sondern es greift bei dieser Neuerung die Anpressungskraft am Umfange der Kreismesser an, wodurch Biegung vermieden wird.The innovation is that the circular knives and their counter knives have conical surfaces have, which act on each other in such a way that when moving the knife axes perpendicular against each other, these conical surfaces slide on each other and thereby the cutting edges of the rotating circular knife come to rest with the cutting edges of the counter knife. With this arrangement, the circular knives are not subjected to bending as in known ones Facilities where the contact force acts in the middle of the knife, but rather With this innovation, it attacks the contact pressure on the circumference of the circular knife, whereby Bending is avoided.

Die Kreismesserwelle « und die Gegenmesserwelle d sind senkrecht gegeneinander verstellbar. Die Gegenmesserwelle d ist, da sie gleichzeitig die Führung der Papierbahn übernimmt, ortsfest gelagert, während die Kreismesserwelle α lotrecht gegen die Welle d verstellt werden kann.The circular knife shaft «and the counter knife shaft d can be adjusted vertically relative to one another. The counter-knife shaft d is, since it takes over the guidance of the paper web at the same time, mounted in a stationary manner, while the circular knife shaft α can be adjusted vertically against the shaft d.

Die auf der Gegenmesserwelle d befindlichen Gegenmesser e, e1, e2. .. weisen an ihrem Umfang auf der einen Seite eine Schneidkante s und auf der anderen Seite eine Kegeifläche h auf. Die auf der Kreismesserwelle α befindlichen Kreismesser δ, δ1, δ2... haben ebenfalls an ihrem Umfang eine Schneidkante i und sind auf der der Kegelfläche k zugekehrten Seite kegelförmig gestaltet (Kegelfläche h). The counter knives e, e 1 , e 2 located on the counter knife shaft d . .. have a cutting edge s on their circumference on one side and a conical surface h on the other side. The circular knives δ, δ 1 , δ 2 ... located on the circular knife shaft α also have a cutting edge i on their circumference and are conical on the side facing the conical surface k (conical surface h).

Since the center of the axes of the circular knife shaft α and the counter knife shaft d are perpendicular to each other, the engagement can be regulated by means of the setting keys f, f 1 and the spring g 2 mm wide strip in every second groove, when cutting a 3 mm wide strip in every third groove etc. of the counter knife shaft d, a circular knife intervenes. The distance between the circular knife b, δ 1 , δ 2 ) is filled in by a correspondingly wide intermediate disk C. The counter knife roller d is ready to be cut with a wall thickness of the counter knife β, e 1 , e 2 ... of 1 mm for all paper strip widths measured in millimeters.
