  • Hide pulling apparatus and method
    Patent number: 4980948
    Abstract: A hide is pulled from the sides of a suspended livestock carcass by gripping the hide with two grippers in the belly area, and pulling the grippers and the hide toward the back of the carcass. The pulling direction is changed by supporting the pulling devices on transversely movable carriages which are moved toward each other during the pulling action. The transverse movement enables the grippers initially to reach farther around the belly to grip the hide, and finally to pull farther toward the spine.
