  • Patent number: 7354339
    Abstract: Dual loin knife blade members, in the form of a Z-blade and two styles (tabbed and non-tabbed) of J-blades, for use with knife assemblies in loin pulling machines for pork processing operations. The Z-blade knife comprises a shelf portion of extended length, formed of two separately-shaped blade portions, to maximize to the allowable customer dimensional length specification for the meat shelf being cut, while not cutting into and exposing the red meat of the pork loin eye. The J-blade, of either the tabbed or non-tabbed style, includes lower sweeping radius blade portions allowing the J-blade to lie closely adjacent and generally conform to the profile of the underlying split conveyor belt bed shape. The profiles for the present Z-blades and J-blades permit substantially increased yield in pork loin processing operations, reduced subsequent hand-trimming labor, as well as extended blade wear.
