ABSTRACT The invention is a method and a machine for cutting a swim- bladder from a spine of a fish after the spine has been removed from the fish or the fish has been flitched. The method includes laying the spine upon a guiding wedge, which perforates the swim-bladder and cuts it open, moving the spine forward toward a motor driven knife, which cuts the swim-bladder free from the spine. The machine includes a cantilever beam which guides the spine toward a horizontal motor driven knife. The guiding wedge is fastened into the frame of the machine. Its lower part is elastic in order to be able to cut different sizes of swim-bladders. The forward motion is powered by a conveying wheel, belt or arm, above the guiding wedge. A single conveying wheel has a rift for the crest of the spine. Two conveying wheels are spaced for the crest. The conveying wheel has spikes for grasping the spine and increasing the friction against it, thereby increasing the conveying force. The guiding wedge has a tip, to perforate the swim-bladder, and a cutting edge for cutting or tearing a hole into the backmost and foremost ends thereof. To prevent accidents, the conveying wheel and knife are both surrounded by a screen.
