ABSTRACT:
A paper shredder includes a pair of cutting rollers and individual strippers mounted on support rods. The strippers extend essentially from the lower and upper outer sides of the cutting mechanism between the cutting disks to the respective roller body. The strippers preferably have crowned stripper portions. A stripper is arranged at the lower side of the cutting mechanism in each gap formed between two adjacent cutting disks by the comb-like engagement of a cutting disk of the opposite cutting roller. Individual auxiliary strippers engaging in every fourth to fifth cutting roller gap are arranged on the upper side of the cutting mechanism. The support rods for the strippers are arranged from the respective outer diameter of the cutting disks at a distance to form openings, wherein the distance is preferably two to ten times the width of the cutting roller gap. For connecting the auxiliary strippers to the support rods, each auxiliary stripper is provided with claw-shaped indentations arranged preferably approximately at the same level, wherein the indentations are located opposite each other and facing outwardly, and wherein the two support rods located immediately opposite each other determine the width of the material intake gap and simultaneously serve the function of a finger guard.
