Abstract
A rotary cutting apparatus in which the cutting of thin material is possible without the use of a curved blade. The fly and bed knives are positioned according to the formula EQU C=R-.sqroot.R.sup.2 -(tangent S.times.L).sup.2 where C is bed knife camber, R is cutting radius, S is shear angle and L is rotor length. As a result of this geometry, uniform fly knife to bed knife clearance is maintained across the face of the rotor.
