  • Patent number: 5580306
    Abstract: A loin separation apparatus and method of operation therefor controls a loin knife assembly in a manner which simulates the anthropomorphic motions of a human operator during a loin pulling operation. The loin knife assembly includes a U-shaped knife blade which is mounted to an arm which is connected to the apparatus through a universal joint to permit lateral and vertical displacement of the knife blade. Moreover, the separation between the sides of the loin knife may be varied. The combination of lateral displacement and varying the separation between the sides of the blade enables the sides of the knife blade to follow separate profiles. The loin separation apparatus generates customized cutting profiles and/or modifies standard cutting profiles for the loin knife assembly, as well as for a scribe saw assembly which may also be included on the apparatus, based upon the particular dimensions, contours, etc. of a specific side of meat.

  • Patent number: 4682387
    Abstract: An apparatus and method for stripping the casing from casing enclosed sausage sticks includes an indexing device which moves sausages in an arcuate path during which the front end of the sausage stick is severed. The sausage sticks are then moved horizontally, front end first, by a positioning conveyor, and the front edges of the casing are engaged by a casing stripper device. The casing is pulled from the sausage stick as the latter is moved by a positioning conveyor. The decased front end of the sausage stick is gripped by a movable gripper device which pulls the sausage from the casing. An ejector mechanism ejects the sausage from the gripper device.

  • Patent number: 4417367
    Abstract: An apparatus for removing the mid-section portion of the skin from the carcass of an animal, such as a hog, includes a revolvable drum mounted on a frame. A flap forming mechanism is mounted on the drum and is operable to form a skin flap and grip the same to hold the skin against the drum during the skinning operation. A skinning blade is mounted on the frame and positioned adjacent the drum to cut the skin from the torso. A skin hold-back mechanism is mounted on the frame and includes an arm having a blade which engages the drum to remove the skin from the drum. This hold-back device engages the drum and dislodges the skin from the toothroll cavity when the mid-section portion of the skin is completely removed from the animal. The frame is mounted on a shock absorbing device which absorbs vertical forces transmitted to the frame during the skinning operation.

  • Patent number: 4351088
    Abstract: An apparatus and method for removing the torso portion of the skin from the carcass of an animal, such as a hog, includes an overhead support from which a carcass is suspended during the skin removing operation. The skin is first removed from the hind quarters of the carcass and then a cut is made in the skin of the torso completely around the carcass just rearwardly of the fore limbs. A flap forming blade makes a longitudinal cut in the carcass and the longitudinal edge of the skin defined by the longitudinal cut is gripped by revolvable toothed cylinders carried by a revolvable drum to form a flap which is wound about the toothed cylinder. A carcass engaging device holds the carcass against the drum during the flap forming operation. A flexible pressurized movable blade positioned adjacent the drum progressively cuts the skin from the carcass as the drum is revolved.
