Abstract

1. An apparatus (1) for shredding waste paper and like materials capable of being torn, by means of a rotor (6) which rotates with a horizontal axis inside a housing (2) and on the circumference of which, swinging beater knives (11) are disposed eccentrically to the rotor axis, which beater knives co-operate, along their beating circle, with a plurality of transverse rows of counterknives supported at the housing side and form a shredding path leading from an input region (4) to a discharge region (5), characterized in that the counterknives (18 to 25, 35 to 38) are adapted, at least in a region preceding the discharge region (5), to the rotational profile region defined by the beater knives (11) and rotor (6) except for a motion gap (39) precluding mutual contact, and in that the discharge region comprises an opening region (32) which cannot be covered.
