Abstract: A poultry breast processing machine having a conveyor adapted to receive forward bilateral poultry carcass sections comprised of the joined breast, back and whole wings and to transport the carcass sections through one or more optional segmenting operations. In one operation the wings are engaged and extended laterally outwardly to cause, in conjunction with the passage of shielded rotary severing knives through stretched shoulder joint connecting tissue and tendon materials, the dislocation of shoulder joints and automated removal of whole wing sections from the carcass section without shattered bone fragment contamination and with substantially no removal of breast meat with the wings. The wing removal operation can be followed by a breast severing operation in which a rotary blade longitudinally splits the breast of the carcass, and then either by a backbone removal operation accomplished by transversely spaced rotary blades or by a back bisecting operation accomplished by a single rotary blade.
