More specifically, the invention provides a particular industrial knife (1), designed for use in a slaughterhouse, in an apparatus (7) intended for cutting and removal of loin back ribs from a pork middle part.
  • Fig. 1 shows a cross-section view of a typical pig middle (M).
  • Middles from pig carcases are usually separated into a loin part (L) and a belly part (B) by being given one or more longitudinal cuts (I, II or III) extending at a distance from the spine (S).
  • the separation may be performed by a cut (I, II) going through the ribs (R), or by a cut (III) going through the meat (M).
  • the most common cuttings of middles are as follows:
  • the invention in its first aspect, relates to an industrial knife for mounting on a slaughterhouse apparatus for automatic cutting and removal of loin back ribs from a pork middle part.

  • knife-body (2) holds one or more spacers (3) arranged perpendicular to the knife-body, and protruding the front edge (2a) of the knife-body (2);
  • knife-body (2) in one end, comprises a fastening element (6) for attachment to a slaughterhouse machine (7).
  • the knife-body (2) of the invention may be made from a stiff or a flexible material, or a combination of a stiff and a flexible material, e.g. having a stiff support area/fastening element (6) for attachment to the slaughterhouse machine, and a flexible active cutting area (see e.g. the distance "x" in Fig. 3).
  • the shape of the knife-body of the invention should fit the curvature of the carcass.
  • the knife-body of the invention is designed to fit the curvature of the ribs, calculated based on a reasonable number of animals. It is currently contemplated that a number of 2-300 constitute a reasonable number of animals, representative of the biological variation.
  • the blade-body (2) should be flexible and have a curvature and a thickness allowing it to straighten or bend somewhat when it is being pressed against the ribs, thus adapting to the shape of the ribs.
  • the thickness of the knife body of the invention should be sufficient to provide a durable tool and may depend on the exact products to be processed.
  • the thickness of the knife body also should have a thickness allowing it to retain its curved shape when in use.
  • a thickness in the range of from about 3 to 8 mm will be enough, e.g. of from about 3 to 6 mm.
  • the knife (1) of the invention When mounted in a conventional slaughterhouse machine (7), the knife (1) of the invention preferably is spring loaded during operation, allowing the curvature of the knife to adjust to the ribs during cutting.
  • the length of the knifes edge (4) should fit the size of meat/rib to be separated.
  • the length of the knife expressed by the distance x (cf. Fig. 3), should be in the range of from 5 to 15 cm, e.g. of from 5 to 10 cm.

  • the active cutting area (x) should be in the range of from about 3-7 cm, e.g. 5-6 cm.
  • the pork carcass is first split onto halves, and each of these halves are usually treated long their own processing lines. This means that two slaughter lines are usually in play, a right-side line and a left-side line. This also, off course, places special demands on the equipment used, and necessitates the use of right-side and left-side equipment, that are essentially mirror images of each other.
  • the industrial knife (1) of the invention represents a right-side knife, adapted to cut and remove of loin back ribs from a right-side pork middle.
  • the industrial knife (1) of the invention represents a left-side knife, adapted to cut and remove of loin back ribs from a left-side pork middle.
  • a replaceable knifes edge (4) is used, and the knife edge (4) can be made of any material, conventionally used in the industry.
  • the knifes edge (4) for of the invention should have a thickness corresponding to the material (meat) to be cut. Is it currently believed that a thickness in the range of from about 1 to about 6 mm is appropriate, e.g. of from about 2 to about 5 mm, or of from about 3 to about 4 mm, depending on the exact nature of the knifes edge.
  • the knifes edge (4) off course must protrude the knife body (2) in order to be able to cut the meat. It is currently believed that the knifes edge (4) must protrude the knife body (2) with a part (represented by the distance y in Fig. 4) corresponding to about 1 to about 10 mm, e.g. of from about 2 to about 8 mm, or from about 3 to about 6 mm.
  • the knife-body (2) of the invention shall hold one or more spacers (3), arranged perpendicular to the knife-body, and protruding the front edge (2a) of the knife-body (2).
  • the spacers (3) guide the knife of the invention and facilitates, that the knife slides and cuts the meat in the desired distance from the ribs, that the knife keeps a uniform, predetermined, distance from the ribs, and that the knifes edge does not hit the ribs.
  • the spacer (3) shall protrude the front edge (2a) of the knifes-body (2) in order to guide the blade into the correct position, when the knife-body (2), fitted to the slaughter house machine used according to the invention, approaches the meat piece (M), and secure that the knifes edge (3) does not catch the rib bone (R).
  • the spacer (3) of the invention should protrude the knifes edge (4) by about 5 to 15 mm.
  • the distance (z) is in the range of from about 5 to about 10 mm, e.g. of from 5 to 7 mm.
  • spacers (3) in the range of from 1 to 10 may be applicable. It is currently contemplated that a number of from 3 to 7 spacers may be applicable for most applications.
  • the spacers (3) shall come in different thicknesses. It is currently contemplated that spacers (3) of a thickness in the range of from 1 to 10 mm will satisfy most customers needs. In one embodiment, the spacers (3) shall be of a thickness in the range of from 3 to 7 mm, e.g. of from 4-6 mm.
