ABSTRACT:
A slicing station for a high speed food loaf slicing machine that slices one, two, or more food loaves simultaneously using one cyclically driven knife blade; the slices are stacked or shingled in groups on a receiving conveyor located below the slicing station. Independent loaf feed drives are provided so that slices cut from one loaf may be thicker than slices from the other. The slicing station, enclosed by a housing except for a limited slicing opening, includes a knife blade having an elongated arcuate cutting edge and a drive that moves the knife blade at a predetermined cyclic rate along a closed cutting path through the slicing range, which range intersects the ends of food loaves fed at predetermined rates into the slicing station. A marker moving with the blade is sensed by a fixed sensor to establish a home position for the blade. There is a honing device to sharpen the cutting edge of one type of blade, with the blade in its home position. A pressure seal is provided to preclude entry of hot water or steam into the slicing station during cleanup. A door mechanism closes off the slicing opening when no food loaf slices are to be cut. The slicing station includes a shear edge member to guide the end of a food loaf into the cutting path of the knife blade.
