Abstract
The machine comprises a frame having an arcuate knife pivotally mounted thereon. A saddle element supports a butt to be trimmed so that it is located in the path of the knife. A clamp-down assembly pins the butt to the saddle so that it is fixed. The knife is curved to conform to the curvature of the lean meat-back fat interface of the butt; the saddle surface is curved to conform to the outer surface of the butt fat layer. In operation, the knife is drawn through the fixed butt and severs a layer of fat of uneven thickness, leaving a layer of generally constant thickness adhering to the lean meat. On the return stroke, the knife pushes the unclamped butt and severed fat from the saddle.
