摘要

The apparatus comprises a knife (21) with a substantially rectilinear cutting edge (27) and mounted in a knife holder (23, 24), a device with a holder for suspending the part carcass by the spine, and means (1, 4, 5) for establishing a relative movement between the part carcass (2) and the knife (21) in a direction in parallel with the spine (9), the knife holder (23, 24) being adapted to displace the knife (21) in a plane perpendicular to the direction of the spine and preferably to turn the knife about an axis in parallel with the cutting edge (27).
