  • Patent number: 4369547
    Abstract: An animal skinning machine. Upper and lower clamp guide trackways guide clamp carriages between which a clamp body is mounted. A first clamp and a clamp frame are carried by the clamp body. Clamp actuators carried by the clamp frame support a second clamp which is movable between a released position spaced from the first clamp and an engaged position for cooperating with the first clamp for engaging a leading edge portion of an animal skin. An elongated knife member is mounted adjacent entry ends of the clamp guide trackways for separating the skin from a carcass of the animal. Upper and lower roller guide trackways guide roller carriages and a roller rotatably mounted on the roller carriages for movement between a retracted position at which the roller is spaced from the knife member and an advanced position adjacent the knife member and spaced therefrom sufficiently to permit the skin to pass between the knife member and the roller.
