<p>A detectable cutter knife (100) is useful as a replacement for a conventional cutter knife (12) used in product inspection and cutting systems (2) of the type having a cutting wheel assembly (10). The cutting wheel assembly (10) includes a knife guide (14) having angularly spaced radially oriented knife support slots (16) through which cutter knives (12, 100) having tangs extending therefrom move between a retracted noncutting position and an extended cutting position. The detectable cutter knife (100) includes a shank (102), a tang (114), and an amount of metallic material in the shank sufficient to stimulate a metal detector (13). The use of metallic material in the shank permits automatic and efficient detection of a broken cutter knife (100) and its removal from product flow (7). Preferably, the metallic material takes the form of a ball bearing (152) secured within a hole (150) positioned in a low-stress area (154) of shank (102).</p> |
