<p>A loop cutter knife fixture for cutting vegetable products such as raw potatoes into spiral or helical loops is disclosed. The knife fixture includes a circular blade holder (22) adapted to be rotatably driven within a vegetable product flow path. The blade holder includes a central core cutter (52) in combination with a spiral base plate defining a radial slot (64) between axially spaced upstream and downstream ends thereof. Small slits (60) are formed in this base plate for seated reception of preferably multiple U-shaped strip blades (62), which are in turn overlaid and clamped in place beneath a generally pie-shaped slab blade (16) having a sharpened knife edge (16’) exposed at the base plate radial slot and held in place by preferably multiple clamp screws (68) and a clap plate (66). The strip blades and/or the slab blade are formed from an inexpensive material, such as sheet metal or the like, whereby blade changeover is quick and economical.</p> |
