The apparatus is further comprised of a means for opening and closing the clamp means. A conveyor means 27 is provided which is adapted to convey the bag with the valve sleeve in the vertical position, toward and away from the clamp means. A bag positioning means is also provided which is adapted to position the bag so that the valve sleeve is inserted in the open clamp means while the bag is being conveyed toward the clamp means. A cycle control means is provided for: (a) stopping conveyance of the bag when the valve sleeve is inserted in the open clamp means; (b) effecting closure of the clamp means with the valve sleeve to seal the interior valve sleeve surfaces together; (c) effecting opening of the clamp means; and (d) starting conveyance of the sealed bag away from the clamp means. |
