In the removal of internal bones in a fore-end of a split carcass the shank bone, the humerus bone and the shoulder blade are cut free by machine, so that subsequently they can easily be removed from the rest of the fore-end. A transport tool () is brought to grip around the free end of the shank bone. The fore-end is then pulled past cutting tools () by means of the transport tool, and the cutting tools () hereby perform cutting operations along the shank bone, the humerus bone and the shoulder blade guided by these bones, so that the bones are at least partially cut free from the rest of the fore-end. The articulations between the shank bone and the humerus bone, and the connections of the humerus bone to the shoulder blade are maintained at least partially unbroken during the cutting operations, so that the tractive force from the transport tool () by the grip of the tool round the free end of the shank bone is transferred to the bones via their unbroken connections.

Method and apparatus for use in removal of internal bones in a fore-end

A suction head for cleaning of the surface of carcass parts consists of an oblong handle () and a nozzle () mounted at one end of the handle. An air duct () passes through the handle and the nozzle, and it can be connected with a suction device via a coupling () in the other end of the handle. Steam ducts () are designed in the nozzle () to lead hot steam to the surface parts () of the nozzle, which are intended to get into contact with the surface of the carcass parts. These steam ducts () are connected with a supply duct (), which is connected with a steam source via a coupling () on the suction head. The supply duct () for steam passes through the handle () from its coupling end to the suction device and to its nozzle end. In the nozzle the duct passes into the steam ducts (). It is less fatiguing for an operator to use this suction head than a conventional head with disinfection facility.
