Abstract
A wing knife holder for a chipping head includes a plinth for releasable mounting of the knife holder to the chipping head hub, a cantilevered member mounted on the plinth, the cantilevered wing inclined rearwardly and radially outwardly, from an inner end of the member support on the plinth to a cantilevered outer end of the member opposite the inner end. The leading edge of the member is forwardly swept in the direction of rotation of the chipping head from the inner end to the outer end so as to advance the outer end ahead of the inner end. A chip flow passage is formed in the plinth, radially inwardly of the leading edge between the hub and the leading edge. The chip flow passage slopes from an inner opening adjacent the peripheral edge of the hub rearwardly and radially inwardly toward the axis of rotation of the chipping head.
