Description
JEs sind Vorrichtungen zum Zerkleinern von Papier bekannt mit zwei ineinandergreifenden, mit verschiedener Drehzahl umlaufenden Walzen, die aus auf Wellen mit Abstand aufgereihten, fräserartig gezahnten Scheiben bestehen. Mit derartigen Vorrich.-. tungen wird zwar eine Zerkleinerung des zugeführten Papiers in Längs- und Querrichtung erzielt; es besteht jedoch, die MögHcn-JEs are known devices for shredding paper with two interlocking, Rollers rotating at different speeds, which are spaced out on shafts lined up, mill-like serrated disks. With such Vorrich.-. It is true that the fed paper is shredded in the longitudinal and transverse directions achieved; there is, however, the possibility
ic keit, daß an den nicht gezahnten Zwischenscheiben, die die gezahnten Scheiben in gegenseitigem Abstand auf der Welle halten, Papier durch das Walzenpaar hindurchtritt, ohne ausreichend zerrissen worden zu sein.the fact that on the non-toothed intermediate discs, which keep the toothed disks at a mutual distance on the shaft, paper passes through the pair of rollers, without having been sufficiently torn.
Erfindungsgemäß bestehen daher die Walzen der Zerkleinerungsvorrichtung aus gezahnten Scheiben von abwechselnd verschiedenem Durchmesser, die ohne Zwischenscheiben unmittelbar nebeneinander auf der Welle aufgereiht sind. Sie bilden so eine auf ihrem gesamten Umfang gezahnte Walze, wodurch eine restlose Zerkleinerung des Papiers in unregelmäßige Stücke gewährleistet wird.According to the invention, therefore, the rollers of the shredding device consist of toothed ones Discs of alternately different diameters, placed directly next to each other on the shaft without intermediate discs are lined up. In this way they form a toothed roller over its entire circumference, as a result of which a complete shredding of the paper into irregular pieces is guaranteed.
Bei Walzenbrechern hat man aus ähnlichen Gründen die Walzen an ihrem gesamten Umfang mit Längs- und Querrippen versehen. Diese Walzenform eignet sich jedoch zur Zerkleinerung von Papier nicht ohne weiteres.In the case of roll crushers, for similar reasons, the rolls have their entire length The circumference is provided with longitudinal and transverse ribs. However, this roller shape is not suitable for shredding paper just like that.
Die Walzen gemäß der Erfindung sind auf der Zeichnung dargestellt. Jede der beiden Walzen« und b setzt sich zusammen aus den fräserartig gezahnten Scheiben c und d von verschiedenem Durchmesser.The rollers according to the invention are shown in the drawing. Each of the two rollers and b is composed of the cutter-like toothed disks c and d of different diameters.
