Dual blade loin knife assembly for automatic loin puller apparatus

摘要

An apparatus for positioning an animal carcass middle and for separating a loin and fatback portion from the carcass middle including a dual blade loin knife assembly for making appropriate cuts to separate the loin and fatback portion. The dual blade loin knife assembly includes a z-blade and a j-blade in which the z-blade separates the loin portion from the belly portion while leaving about a 2 inch to about a 2⅝ inch shelf on the belly portion incorporating an amount of "finger" lean while leaving a portion of finger lean on loin portion and the j-blade separates a selected depth of fatback from the loin portion based on the desired profile. The j-blade is positioned proximate the z-blade such that the carcass middle engages the j-blade subsequent to engagement of the z-blade. The dual blade loin knife assembly increases the useable size of a shelf cut on the belly portion of the carcass middle.
