摘要

The cylindrical or conical rotor (3) supports a cutting screw (4), the cutting edge (5) of which rises above the rotor by the thickness of the cut piece (a). The cutting face of the screw in the area of the cut piece includes an angle which is less than 90 degrees in relation to the feed unit. The rotor has a continuous slot (7) lying opposite the cutting edge of the screw. An Independent claim is included for a cutting screw which has a cutting edge which is curved in the region of the cut piece thickness. The screw overlaps the draw-in side of the feed funnel at least by a complete screw thread.
