Die Erfindung bezieht sich auf eine Vorrichtung zum Zerschneiden von Papierrollen in einzelne Scheiben mittels eines in die Papierrolle eindringenden Messers. Die Erfindung selbst besteht in der Anordnung des Messers.The invention relates to a device for cutting paper rolls into individual slices by means of a knife penetrating the paper roll. The invention itself consists in the arrangement of the knife.

Zunächst ist zu bemerken, daß es bei denFirst of all, it should be noted that the
ίο im Handel bezogenen Papierrollen wegen ihrer ziemlich lockeren Aufrollung oft nicht möglich ist, mittels eines Messers oder dergl. saubere, brauchbare Längsstreifen in Form von Scheiben zu schneiden. Es ist daher zunächst eine Umrollung der Papierrollen zu einer festeren Rolle erforderlich, zu welchem Zweck die in der üblichen Weise mit einer hölzernen Welle versehene Rolle in die Lager α eingesetzt wird.Often it is not possible to use a knife or the like to cut clean, usable longitudinal strips in the form of slices for commercially available paper rolls because they are rather loosely rolled up. It is therefore first necessary to rewind the paper rolls to form a firmer roll, for which purpose the roll, which is provided with a wooden shaft in the usual way, is inserted into the bearings α.
Der Papierstreifen wird alsdann über die Führungswelle f auf eine in die Lager b eingesetzte Welle geleitet und durch Drehung der letzteren mittels einen Handrades oder dergl. neu aufgerollt.The paper strip is then guided via the guide shaft f onto a shaft inserted into the bearings b and rolled up again by rotating the latter by means of a handwheel or the like.
Parallel zu dieser Rolle sind in dem Gestellrahmen Gleitstücke angebracht, auf welchen ein in beliebiger Entfernung feststellbarer Schlitten sich befindet. In letzterem ist eine Schraubenspindel gelagert, mittels welcher eine Mutter quer zur Achse der Papierrolle bewegt werden kann. In dieser Mutter ist nun gemäß der Erfindung ein Messer m derart festgeklemmt, daß es mit der zu schneidenden Papierrolle einen spitzen Winkel von etwa 350 bildet. .Parallel to this role, sliding pieces are attached in the rack frame, on which there is a slide that can be locked at any distance. In the latter, a screw spindle is mounted, by means of which a nut can be moved transversely to the axis of the paper roll. In this mother of the invention is now in accordance with a knife m clamped such that it forms an acute angle of approximately 35 0 with the material to be cut paper roll. .
Das Schneiden der Längsstreifen von der in der vorbeschriebenen Weise neu hergestellten Papierrolle geschieht nun in der Weise, daß während'der Drehung der Papierrolle in diese das Messer mittels der Ge- windespindel eingeschoben wird.The cutting of the longitudinal strips from the newly produced in the manner described above Paper roll is now done in such a way that during the rotation of the paper roll in this the knife by means of the the winding spindle is pushed in.
Hierbei ist die Drehung der Rolle in der auf der Zeichnung durch einen Pfeil angedeuteten Richtung zu bewirken, wodurch das Messer in der Rolle selbst eine feste. Führung erhält und schlingernde Bewegungen ausgeschlossen sind. Durch die schräge Stellung des Messers wird ferner erreicht, daß das Messer m — im Gegensatz zu ähnlichen Ausführungen — an einer möglichst langen Schneidfläche beansprucht und somit ein vorzeitiges Stumpfwerden und Auswechseln desselben vermieden wird.The rotation of the roller is to be effected in the direction indicated by an arrow in the drawing, whereby the knife in the roller itself becomes fixed. Guidance is maintained and lurching movements are excluded. The inclined position of the knife also ensures that the knife m - in contrast to similar designs - stresses the longest possible cutting surface and thus prevents it from becoming blunt and replacing it prematurely.
