  • Patent number: 4189897
    Abstract: A high speed evacuation chamber packaging and clipping machine for the high speed evacuation and positive sealing of filled, flexible receptacles such as thermoplastic bags in order to preserve the contents of the receptacle. A first endless conveyor carries a plurality of bagged product carrying platens. The first conveyor conducts the platens along a horizontal path of travel with the platens facing upwardly. A second conveyor carries a plurality of hoods. The second conveyor conducts the hoods between and along upper and lower paths of travel and is so located with respect to the first conveyor that when each hood is shifted from its upper path of travel to its lower path of travel, it will engage one of the platens traveling in its horizontal path of travel to form a chamber therewith. Means are provided in association with each chamber for evacuating the chamber. Means are also provided in association with each chamber for applying a clip to the bag to close the bag about the product.
