  • Rotary cutter head
    Patent number: 6119741
    Abstract: A rotary cutter head is provided having body shape characterized, generally, outwardly-shifted cylinder segments to shift cutter head weight and force to the knife blades and to balance and extend the knifes from the central core of the cutter head while reducing workpiece waste buildup along the knife front, and while decreasing clogging of knife mounting components and reducing over-heating of knives and with securing corrugations on the knife cutting face, engageable with corrugations on the cutter head for securing the knife base against a foot on the cutter head.
