Claim 5:
6. A slaughtered pig part processing plant comprising:
a plurality of pig part processing stations; and
a conveyor supporting, via respective couplings, spaced apart clamp structures for carrying pig parts, said conveyor advancing said couplings with a respective one of said clamp structures for each of said couplings in a machine direction (T);
said couplings each comprising an upper structural part and a lower structural part connected with said respective one of said clamp structures, said lower structural part being mounted for rotation about a vertical axis (D) relative to said upper structural part;
said lower structural part comprising:
an upper body having a periphery defined by a number of first edges extending at a first level;
a lower body having a periphery defined by a number of second edges extending at a lower second level; and
wherein said upper body and said lower body are fixed to one another, said periphery of said upper body and said periphery of said lower body are identical, said upper body being angularly offset at an angle (a) about said vertical axis (D) relative to said lower body, and said respective one of said clamp structures is fixed to said lower body;

a first subset of guiding faces at said first level for engaging said upper body to bring about a rotation about said vertical axis (D) when said coupling is advanced in said machine direction (T) past said first subset of guiding faces;
a second subset of guiding faces at said lower second level for engaging said lower body to bring about a rotation about said vertical axis (D) when said coupling is advanced in said machine direction (T) past said second subset of guiding faces; and
wherein upstream and/or downstream of said first subset of guiding faces and said second subset of guiding faces, a group of two elongated guiding faces arranged opposite one another and extending along said machine direction (T), both of said two elongated guiding faces at one or the other of said first level and said lower second level, for preventing or restricting said rotation by engagement with an edge of said upper body or said lower body.
