Slabbing apparatus and method

Abstract

Apparatus and method for automatically subdividing carcasses, especially fish bodies, into individual slab sections. A preferred embodiment of the cutting apparatus includes a feed mechanism and a cutting mechanism coordinated by computer. The feed mechanism comprises a motor-driven carriage that rides upon rails. Between the rails is a feed track formed by parallel guides having angled facing surfaces defining a channel to accommodate a fish body aligned along the channel. A retainer on the carriage secures the head end of the fish body so that it can be advanced along the channel by the carriage without a change in orientation. The cutting mechanism includes a reciprocating blade that is advanced in a direction to define a cutting plane intersecting the path the fish body takes as it is transported by the carriage beyond the end of the feed track. Holding blocks at the end of the feed track clamp the fish body securely in position for cutting. The blade slices through the stationary fish body to sever a slab section from one end with minimal kerf loss and shredding. A slab holder is inserted in the peripheral girth of the severed slab section before both are conveyed off. The process is repeated until the fish body is subdivided into a predetermined number of slab sections with each of the severed slab sections held by its own holder in the same relative location so that the general orientation of the severed slab can be determined in downstream processing by reference to the holder.
