  • Patent number: 5435114
    Abstract: The present invention relates to an automated packaging machine for packaging poultry products and a method for packing poultry products using the machine. The machine includes a loading station wherein the product is loaded into a bag and a sealing station for closing the bag. A first clamp arrangement is used to capture and control edges of the bag during the loading operation and to move the bag with the product therein to the sealing station. The machine also includes guides for supporting the product during loading, a plunger for breaking the hocks, and a mechanism for introducing a vacuum into the bag before sealing.

  • Patent number: 4616472
    Abstract: A method and apparatus for automatically loading side seal bags, at least two at a time, which comprises delivering the bags to a first position below a rod conveyor which has a gap therein through which the bags are pulled and loaded in a second position. The bags are then conveyed away on the rod conveyor. Speed of loading is increased because succeeding bags are moved to the first position while the previous bags are loaded at the second position. The movement from the first to second position is short and relatively quick.

  • Patent number: 4550548
    Abstract: A method for vacuum shrink packaging a product is provided that includes the steps of placing the product in a heat shrinkable thermoplastic bag; then shrinking the bag in a heated gaseous medium, while partially constricting the mouth of the bag to cause ballooning of the bag, further provided that the constricting is selected such that shrinkage of the bag overcomes the ballooning to collapse the bag onto the product; and then placing the bag in a vacuum chamber followed by vacuumizing and in-chamber sealing, further provided that the rate of vacuumizing is limited to substantially prevent reballooning of the bag. Associated apparatus for carrying out the method is also provided.
