Abstract

An apparatus for severing the fillets from fish rumps comprises cutting tools each composed of pairs of circular knives for cutting free the belly spokes, the back spokes and the ribs or vertebral appendages, respectively. The last mentioned cutting tool has a double function which consists in that each circular knife of this tool is associated with a guiding element, which, in its rest position, lies against the inner face of the circular knife with its guiding face. The guiding edges of the guiding elements support the vertebrae of the vertebral column and can be displaced within the cutting planes of the circular knives and can be controlled, in their displaced position, into a position in which a gap for the passage of the ribs or the vertebral appendages is opened between the inner face of the circular knives and the guiding face. The displacement of the guiding elements occurs by the effect of transporting disks, which support the vertebrae of the vertebral column on the opposing side.
