1. Schneidevorrichtung für einen Aktenvernichter, um­ fassend:
ein Basiselement;
zwei am Basiselement drehbar montierte und miteinander in Eingriff stehende Schneideelementsätze, wobei die beiden Schneideelementsätze jeweils eine polygonale Welle, Mehrfachschneideelemente und -separatoren umfassen und die Schneideelemente und Separatoren abwechselnd angeordnet und auf die Welle aufgeschoben sind;
vom Schneideelement aus radial nach außen verlaufende Mehrfachzähne, die am äußeren Abschnitt davon eine Schneidekante bilden;
eine im oberen Abschnitt der Schneidekante der Zähne definierte erste V-förmige Nut; und
vom Basiselement aus verlaufende und den Separatoren entsprechende Mehrfachvorsprünge;
wobei die Verbesserung umfaßt:
einen vom Separator aus radial nach außen verlaufenden Flansch, der in der ersten V-förmigen Nut des Schneideelements aufgenommen wird; und
eine in der Stirnfläche des Vorsprungs definierte zweite V-förmige Nut, wobei die zweite V- förmige Nut den Flansch des Separators mit einem geringfügigen Abstand aufnimmt.1. Cutting device for a paper shredder, comprising:
a base element;
two cutting element sets rotatably mounted on the base element and in engagement with one another, the two cutting element sets each comprising a polygonal shaft, multiple cutting elements and separators, and the cutting elements and separators being arranged alternately and pushed onto the shaft;
multiple teeth extending radially outward from the cutting element and forming a cutting edge at the outer portion thereof;
a first V-shaped groove defined in the upper portion of the cutting edge of the teeth; and
multiple projections running from the base element and corresponding to the separators;
the improvement includes:
a flange extending radially outward from the separator and received in the first V-shaped groove of the cutting element; and
a second V-shaped groove defined in the end face of the projection, the second V-shaped groove receiving the flange of the separator at a slight distance.
