Abstract
Frozen slabs of fish are introduced one at a time to one end of a conveyor having a bed of laterally spaced plastic strips forming slots therebetween. Beneath each slot is an endless chain having a series of upwardly directed fingers thereon. The fingers are engageable with the various slabs so as to advance the slabs to a location beneath an assembly of water jet devices, each device including a pivotal arm having a nozzle at one end thereof. A barrel cam has a plurality of tracking grooves, the pivotal arms having cam followers depending downwardly therefrom into the tracking grooves of the barrel cam. As the slabs are successively advanced beneath the liquid jet devices, the jets cut the particular slab into individual portions. Advancement of the now severed portions cause the portions to be moved onto a plurality of tilt strips which prevent the cut edges from freezing together. The individual portions are then delivered onto a spreader conveyor assembly comprised of three angularly oriented sets of rollers, two of the sets flanking the first or central set and causing the individual portions to traverse a diverging path for subsequent processing.
