Abstract

Für den Antrieb der Schneidwalzen eines Aktenver­ nichters wird zur Senkung des Geräuschpegels neben der Verwendung von Kunststoffzahnrädern (4 bis 6) auch eine völlige Kapselung des Getriebes (3a, 4, 5) vorgenommen. Hierzu dient neben dem Lager­ schild (7) der Antriebsstufe (4) eine aus schall­ dämmendem Material bestehende Abdeckhaube (8) an der Frontseite des Schneidwerksgehäuses (G) For driving the cutting rollers of a file ver nothing is next to lowering the noise level the use of plastic gears (4 to 6) also a complete encapsulation of the gear (3a, 4, 5). This is used in addition to the warehouse shield (7) the drive stage (4) one from sound insulating material existing cover (8) the front of the cutting unit housing (G)
