Abstract
A device for making an incision around the vent of a slaughtered bird and pulling the end of the rectum out of the opening thus made, including: a centering pin which is movable relative to the bird, and is provided with a thickened end portion; and a cylindrical rotary cutter with an annular cutting edge, which cutter is movable relative to the bird and is movable coaxially relative to the centering pin. The device further comprises one or more holding elements which are recessed relative to the cutting edge and which can interact with a contacting surface of the thickened centering pin end portion situated opposite them for holding the vent between these elements and the contacting surface near or at the orbicular muscle. The drive of the cutter is designed in such a way that the cutter carries out a small number of turns during the cutting operation. The holding elements may be made in the form of one or more pins which project axially with the cutter towards its cutting edge, and which are intended for piercing the vent near or at the orbicular muscle. A holding element may also consist of a principally annular protuberance along the inner circumference of the cutter.
