Definitions
- the invention relates to a cutting device for document shredders according to the preamble of claim 1.
- a document shredder is known, the one Has pair of cutting rollers with individual wipers.
- the individual wipers are held on continuous rods are both in the area of The upper side of the cutting unit and the lower side of the cutting unit.

Two adjacent individual wipers lie on a gap to each other so that the cutting disks and the individual wipers are comb-like can interlock.
- GB-A-2 137 116 is a document shredder with one Scraper known in the area of the cutting unit. This publication but does not disclose how to assign the two cutting rollers Intermesh wiper elements over the length of the cutting rollers.
- the present invention has for its object by a new one Wiper training and a new arrangement of the same to the rollers one Reduction in the number of wipers and thus on the wiper rods to achieve acting forces.
- stripper plates E 1 and E 2 are arranged on the top and bottom of the cutting unit, individually or as a group GR 1 or GR 2 to form two or more stripper plates E 1 or E 2 , at a gap Lü are; as a further important feature, the gap distances A 1 and A 2 are kept different in size.
- the foot parts of the scraper plates E 1 on the cutting unit upper side are brought up to approximately the clippings insertion gap ESP of the cover hood (not shown) and open there flush in longitudinal finger protection rods ST, with the entire scraper system also advantageously being within the vertical projection VP of the cutting rollers 1, 2 with 3, 4.
