Abstract: A continuous conveyor assembly 11 comprises a plurality of conveyor plates 18 that define a longitudinal space 19 along the center portion of the conveyor. Carcass supports 21 are carried by the conveyor assembly at spaced intervals for transporting poultry carcasses 44. Breast support brackets 34 are mounted on the conveyor assembly adjacent each carcass support 21 for supporting the breast just above the conveyor assembly. The conveyor assembly carries the carcasses first through a pair of wing-cutting disks 48, then about a breast-cutting disk 51 that protrudes upwardly through the slot of the conveyor to cut the downwardly-facing breast of each carcass, and then through a back-cutting station 43 where the backbone is either split by a backbone cutter 62, or is cut from the carcass by a pair of spaced cutting disks 60 and 61. A guide 50 extends between the pair of back-cutting disks or about the backbone cutting disk to stabilize the carcass as the back is being cut.
