<p>A drum-type wood chipper (10; 210) having a chipper drum (23; 223) with knives (76) mounted in openings (62) in the drum wall (60). A chip basket (70) is mounted within the drum behind each knife opening. The chipper knife (76) is spaced from the drum wall (60) at both the leading edge (110) and trailing edge (112) of the knife to define a chip ingress opening (120) and a chip egress opening (122) for the chip box. Cut chips pass into the chip box as the leading edge of the knife chips the infeed material; and the chips are carried by the box for subsequent discharge through the egress opening into a discharge chute (22). <IMAGE></p> |
