Claim 16:
17. A method of operating 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, said conveyor advancing said couplings with a respective one of said clamp structures for each of said couplings in a machine direction (T) from a first station for introducing a pig part between a first jaw and a second jaw of said one of said clamp structures, towards a last station for removing a bone of said pig part from said one of said clamp structures;
wherein said one of said clamp structures comprises a carrier part carrying said first jaw and said second jaw, said first jaw comprising a first edge oriented towards a second edge of said second jaw, said first edge and said second edge defining between them a gap (G1);
wherein said first jaw comprises a first face and an opposite second face;
wherein said first jaw being mounted to turn relative to said carrier part about an axis (A) from a first position to a second position where said gap (G1) is opened up, wherein a force applied against said first face turns said first jaw from said first position, a biasing force biasing said first jaw towards said first position at least when said one of said clamp structures move away from said first station;
said method comprising:
arranging said one of said clamp structures with said first face oriented vertically or essentially vertically at said first station (40);
moving said pig part against said first face to open said gap (G1) by a portion of said pig part turning said first jaw about an axis (A);
inserting said pig part into said gap (G1) opened by said pig part; and
turning said one of said clamp structures into a position with said first face and said second face oriented generally downwards for said one of said clamp structures to carry said pig part by said first edge and said second edge biting into said pig part.
