In a cutting mechanism for a document shredder a pair of cutting rollers are disposed in side-by-side relation with disk-shaped circular cutters spaced apart on the rollers. Adjacent circular cutters form annular grooves between them so that the circular cutters on one roller extend into the annular grooves on the other. Wiper plates are located in the annular grooves between the cutters and are arranged in a row extending in the axial direction of the rollers. The wiper plates have tips arranged in a pointed manner with the tips located at the outer circumferential surface of the roller cores. Further, strip-shaped support rods maintain the wiper plates adjacent to the cutting rollers and resting in a positively locked manner on the outer circumferential surfaces of the circular cutters. Each support rod has a pointed tip which engages into an undercut groove in a radially outer surface of each wiper plate.
