<p>A series of hogs are hung by their hamstrings and moved progressively along a conveyor. The skin is cut from the belly, legs and head of each hog and then heads of the hogs, by pairs, are held down while the skins of the hogs, by pairs, are pulled upward. The skins are pulled upward over a tent-shaped backing to protect the mechanical portions of the puller from blood and offal.</p> |
