  • Patent number: 5250005
    Abstract: A method for automatically cleaning fish such as cod comprises gripping the fish and subsequently cutting it open, first transversely behind the head from the belly of the fish and subsequently in its longitudinal direction along the belly, and finally removing the entrails.

  • Patent number: 5149296
    Abstract: A method and a machine for processing belly flaps from a front part of a fish which has been parted into a rear part and a front part. According to applicant's co-pending U.S. application Ser. No. 716,738, it is known to move by spiked chain at each side, the front part of a fish with the belly foremost and the head farthest back, along a fixed straight track to a fixed U-shaped beam, which is a belly scraper. The belly of the front part is threaded upon the belly scraper which scrapes the inside of the belly cavity so that the entrails are loosened from the front part and moved into and along the belly scraper. The leading end part of the belly scraper has a knife edge and an elevation in the floor, and cuts the pectoral nose from the gills and the tongue so that the tongue moves into the belly scraper, which pierces downward and out from the head through the pectoral nose. The jaw bones move on top of the belly scraper along its upper edge, and the belly flaps move to the sides.

  • Patent number: 5135432
    Abstract: A method and a machine for cutting a nape muscle of a fish from a front-part of a fish, after the fish has been parted, and removing the fish skin from the nape muscle. The method includes moving the front part along a fixed, straight track to and past vertical circular knives which cut vertical cuts at each side of the spinal crest and at the same time to and past horizontal fixed knife blade edges, fixed on the leading portion of a plough structure, which in turn is fixed to the shaft mount for the shaft of the circular knives. The plough structure cuts lateral cuts from the spine to the skin, but not through the skin. The outermost side part of the plough structure, the plough spade, is not sharp and is used to tear the nape muscle from the attached skin, when the skin is pulled forwards through a gap formed between the plough spade and a sliding table below the plough structure, the nape muscle being retained at the upper surface of the plough structure.

  • Patent number: 5106334
    Abstract: The invention includes a method and a machine for removing spine 2, headbone 13 and organs 4, 5, 6 and 10 from a front part 1 of a fish "parting" of the fish into two parts, rear part and front part 1, where the pectoral nose 9 is uncut, and the pectoral bond 20 is uncut, and the belly cut 39 does not separate the lower end of the pectoral bones 19. The method includes moving, by means of a spiked chain at each side, the front part 1 with the belly 3 at front and the head 18 at rear along a fixed straight track 21 to a fixed U-formed beam comprising a belly scraper 16 at the end of the spiked chains 23. The belly 3 is threaded upon the belly scraper 16, which scrapes the inside of the belly 3, so that the organs get loose from the front part 1 and are moved into the belly scraper 16.At front of the belly scraper 16 is a gill knife 17, which cuts the lower ends of the gills 10 from the radix of the tongue 8.

  • Patent number: 4599765
    Abstract: The invention concerns a device for beheading fish whose throat has been cut by opening the gill cavity from the belly side. To carry out the decapitating cut the fish is seized conveyingly by means of an entraining element engaging the gill cavity after alignment with respect to the gill cavity with the help of a pin-shaped support element and moved against the cutting device by displacement of a back support which supports the back of the fish resiliently. The cutting device may either comprise a plane cutting knife or a pair of wedge cutting knives.

  • Patent number: 4583265
    Abstract: The invention concerns a device for processing fish heads, especially for separating pieces suitable for human consumption, especially the cheeks, the chin flesh and the tongue resp. the gills, the latter being unsuitable for human nutrition. The device is characterized in that a feeding trough receiving the fish head in swimming position is provided, a feeler being arranged at its end to activate a conveyor which engages the fish head behind the lower jaw while opening the pharynx and pushes it on the spear-shaped end of a guide. In the region of the guide the fish head is taken over by a conveyor extending over and along the guide and guided to a cutting device for separating the fish head, the gills being ripped out beforehand by spreading flaps arranged on the flanks of the guide.

  • Patent number: 4389750
    Abstract: An apparatus is disclosed for mechanically decapitating fish, in which fish lying on one of their sides are conveyed transversely and decapitated by a wedge-shaped cut by means of a decapitating tool. In order to perform an exact symmetrical and economical decapitating cut independently of the respective size of the fish to be processed the decapitating tool is mounted pivotably about a pivot axle extending in the plane of symmetry of the same and parallel to the conveying direction of the fish. The adaptation proceeds automatically through a pair of centrally synchronized feeler rails which are borne on the housing carrying the knives of the beheading tool.
