ABSTRACT:
In severing the heads of fishes by a wedge-shaped cut, after their gill cavity and abdominal cavity have been opened, and after they have been gutted, the head of the fish is aligned and secured in position and, after the beheading cut has been accomplished, the parts containing the collar bones are separated from the head by guided cuts into the gill cavity whereupon the separated parts with the collar bones may be conveyed to be further processed in a well known manner to separate the meat from the bones. The device for carrying this method into effect comprises a machine frame carrying an intermittently advanced conveyor having receiving means for the fishes mounted thereon. A head severing device is mounted on the machine frame laterally of the conveyor and includes a pair of circular knives arranged angularly with respect to each other, said circular knives being mounted for pivoting motions transversely relative to the path of movement of the fish about an axis extending in parallel relation to the path of movement of the conveyor. Downstream of the head severing device, spaced therefrom about the distance between two adjacent receiving means, a device for separating the meat parts containing the collar bones from the head is mounted on the machine frame which separating device includes a pair of circular knives arranged in a common plane with their adjacent cutting edges spaced equally from the vertical plane of symmetry of the receiving means when the conveyor is stopped so as to form a gap therebetween and mounted for pivoting motions through the path of movement of the receiving means.
