  • Method and an apparatus for cutting free and removing the rectum of a carcass of a slaughtered animal, preferably pigs
    Patent number: 5419738
    Abstract: A method of cutting free and removing a rectum of a carcass of a slaughtered animal hanging by the hind legs with a head downwardly. An apparatus including a rotating tubular knife is positioned in the vicinity of the rectum of the carcass. A guiding pin on the apparatus is inserted into the rectum of the carcass coaxially with a main axis of the rectum. The guiding pin is arranged coaxial with the rotating tubular knife. The rotating tubular knife is moved into the carcass coaxially with the main axis of the rectum, thereby cutting the rectum free of the carcass. The rectum is retained in the rotating tubular knife. The rectum is pulled free of the carcass toward a ventral side of the carcass in a direction substantially perpendicular to a main axis of the carcass. The rectum is hung downwardly over a side of a protective shield. The side of the shield faces away from the carcass.
