Abstract
As the stripper (20) for the cutting mechanism (13) of a document or paper shredder (11) is provided a plastic part, which can be injection moulded in one piece and entirely surrounds the shaft (18) of the cutting rollers (15) in the gap (17) between the cutting disks (16). In the overlap area (23) between the two cutting disks is provided a thin, flexible stripper web (24), which makes it possible to open the separation point (36) of the stripper separated with respect to the flexible circumferential portion (24) to such an extent that it can be snapped over the shaft (18). The stripper can be manufactured as a single component or as a stripper block with several to all the strippers of a cutting roller. This leads to a low friction stripper preventing cut particles winding round the shaft.
