ABSTRACT:
In a document shredder (1) each tool roller (7, 11) has two tool strippers (8, 9 or 12, 13) with in each case at least one support rod (15) and associated stripping bodies (28), so that two rows of stripping bodies (28) are provided in spaced manner in the circumferential direction of the tool roller (7, 11). In the vicinity of at least one longitudinal area of the tool roller (7, 11) particularly prone to bending deformation in place of the stripping body (28) is provided a support body (30), which positively connects the support rods (15) of two tool strippers (8, 9 or 12, 13) and the tool rollers (7, 11) and which can also act as a stripper. As a result of the frame-like locking of the tool roller and the support rods a significant stiffening occurs, which makes it possible to give smaller dimensions to the tool roller (7, 11) and/or the support rods (15).
