Abstract: A method of, and an apparatus (1) for, continuously harvesting surrounding meat from a successive plurality animal legs having articulated first and second animal bones and an intermediate joint. The method continuously conveys the animal legs through a path of conveyance, and determines a location of the intermediate joint. Based on the determined location of the intermediate joint, adjusting a position of the intermediate joint and a cutting implement relative to one another, and performing cutting of tissue at a location commensurate with the location of the intermediate joint. The step of determining the location of the intermediate joint is performed contactless, and without interrupting continuous conveyance of the animal legs.

Abstract: A meat stripper is disclosed for stripping meat from the bone of an animal part. The meat stripper includes a slide block and a first stripper plate assembly including an arm pivotally mounted to the slide block and having a first stripper plate at an opposite end. A second stripper plate assembly including an arm is pivotally mounted to the slide block and has a second stripper plate at an opposite end with the second stripper plate opposing the first stripper plate. The first and second stripper plates move away from each other to open the meat stripper when the arms are pivoted apart and move toward each other to surround the bone when the arms are pivoted together. A mechanism is disclosed for moving the stripper plates along the length of the bone to strip meat from the bone.

Abstract: A method of automatically removing meat from an animal extremity that includes first and second bones articulated by a joint and surrounded by the meat. The method includes obtaining the animal extremity, holding the first bone at a free end thereof remote from the joint, separating the meat from the first bone while moving the meat lengthwise of the first bone in a direction toward the joint, and moving the meat just short of the joint. The method further includes severing the second bone from the first bone adjacent the joint, collecting the severed second bone with the meat attached thereto, holding the thus collected second bone at a distal end thereof and removing the meat from the second bone longitudinally thereof.

Abstract: A method and apparatus for removing a knee cap from a poultry part, and particularly a deboned poultry thigh, includes a plurality of bays attached to an endless conveyor and movable by the conveyor in a processing direction. Each bay includes a plate sized to support a poultry thigh and having an aperture formed therethrough. A plunger assembly includes a plunger tip that can be moved selectively into and out of the aperture by a cam mechanism. Poultry parts are placed by workers on the plates as they move in the processing direction with the knee caps of the parts aligned with and pressed partially into the apertures. The cam mechanism then moves the plunger tip of each bay into its respective aperture to press the knee cap through the aperture, where it is severed by a rotating knife. The plunger tip is then withdrawn for a successive processing cycle.

Abstract: A method of removing a sleeve of meat (D) from an animal part having a bone with a first knuckle (B) on one of two opposite ends of an elongate bone shaft (A) and a second knuckle (C) on another of the two opposite ends. The method includes the steps of engaging the bone of the animal part with a part of a meat stripper (13) between its first knuckle (B) and the sleeve of meat (D) and engaging the bone by a knuckle gripper (71) between the part of the meat stripper (13) and the first knuckle (B). The method continues with moving the meat stripper (13) and the knuckle gripper (71) away from one another, while stripping and gathering the sleeve of meat (D) towards the second knuckle (C). In a subsequent step the method discontinues moving away the meat stripper (13) and knuckle gripper (71) from one another upon the part of the meat stripper (13) engaging the second knuckle (C).
