  • Patent number: 5119615
    Abstract: A plurality of clamps arranged in equally spaced relation on an endless track are intermittently advanced at a pitch equal to the distance of each two adjacent clamps. A switch reactive only to the passage of a sufficiently heavy or filled bag which has been filled with an article is disposed downstream of a filling station, one of the stop positions for clamps. When the passage of a bag is not responded by switch, that is, when an empty or unfilled bag has passed near the switch, the particular clamp by which the empty bag is held is caused to pass through the final stop position and, in turn, through the first stop position before it can again reach the filling station, with the empty bag being held by the clamp all the while.

  • Patent number: 4723392
    Abstract: Pressure resistant containers, each consisting of a pressure resistant box opened at the front surface thereof and a wall plate, are circulated along an endless track with the wall plates directed outward. The front and back surfaces of each wall plate are each provided with a clamp for supporting a soft pliable bag. The bag is fed to the clamp disposed outside the pressure resistant container, and the bag is clamped by the clamp. The mouth of the bag is then opened to fill the bag with an article. Subsequently, the wall plate is turned inside out to admit the bag in the pressure resistant container, and the bag is subjected to a vacuum in the pressure resistant container and the mouth of the bag is sealed.
