  • Patent number: 4457048
    Abstract: An apparatus for use in pig-slaughterhouses for the removal of the toe-web between the toes of the hindlegs of a slaughtered pig. The bodies of slaughtered pigs, vertically hung on carrying-yokes, are carried by a conveyer. The bodies are oriented by a spring-loaded yoke so that they will pass through a removing-station with the hindlegs perpendicular to the direction of transportation. A double swing is placed on each side of a rotating milling-cutter (of the metal-milling type). The swing allows the milling-cutter to rotate in a plane parallel to the direction of transportation. The milling-cutter also positions itself with an elongate guide into the right position for each subsequently arriving and passing pair of hind-legs.
