Method for providing a cut around the anus of an animal, which is suspended at its back feet, to free the rectum from the carcass, which is suspended at its back feet, and apparatus for performing said method. A b s t r a c t Method for providing a cut around the anus of an animal, preferably a hog, to free the rectum from the carcass, which is suspended at its back feet, according to which method a rotating, tubular knife is advanced towards the anus of the animal for making a cut around it in a predeterminded depth. With the purpose of obtaining an automatized cutting process to free the rectum of animals, which may vary as to size and also be individually different, the method is characteristic in that the carcass is fixed with respect to a vertical plane through the axis of the knife, that the hind part of the carcass is fixed with respect to a vertical plane perpendicular to the first plane, that a linear sensor parallel with the second plane is moved downwards in a substantially vertical direction in such a distance from the second plane that it hits the root of the animals tail, and that the rotating knife is adjusted to af predetermined position with respect to the sensor, when it is hitting the root of the tail, after which the sensor is moved to an inactive position out of the way of the knife, whereafter the cut is made.
