ABSTRACT:
In a rotary cutter block a blade is clamped in an inwardly divergent recess by a wedge. A spring positioned between the cutter block and the wedge takes up any slack when the wedge is loosened thereby eliminating the need for operator manipulation of the wedge, blade and optional backing plate for the blade during setting of the blade. Also provided is a cam means for incrementally adjusting the blade outwardly of the cutter block.
