ABSTRACT:
A self-cleaning cutter knife (100) is described for use as a replacement for prior art cutter knives in product inspection and cutting apparatus having a cutting wheel assembly including a knife guide having angularly spaced radially oriented knife support slots through which cutter knives having tangs extending therefrom move between a retracted noncutting position and an extended cutting position. The self-cleaning cutter knife (100) includes a shank (102) and a tang (114) similar to those of prior art cutter knife (10) but also includes a secondary blade (126) whose cutting edge (128) is positioned to cut product remnants adhering to the shank (102) as it retracts into the cutting wheel assembly. The secondary blade (126) diminishes the knife jamming that results from accumulation of large product remnants in the cutting wheel assembly knife slots.
