Abstract: A valve bag is provided having a self-closing feature to preclude sifting losses after filling, but before the bag is fully sealed, while enabling the facilitated final secure closure of the bag.

Abstract: A method and apparatus for sealing a valved bag transported by a conveyor. The valved bag has a body with a longitudinal axis, a center of gravity, and a sealable valve. At least a portion of the sealable valve protrudes from the body in a substantially perpendicular orientation relative to the longitudinal access. The apparatus includes a conveyor for transporting the valved bag in a direction of travel substantially parallel to its longitudinal access. A stop member stops the transportation of the valved bag when the sealable valve is aligned with a sealing area. A ram member positions the valved bag to dispose at least a portion of the sealable valve into the sealing area. An ultrasonic horn and anvil engage and seal the sealable valve. The stop member is removed from the path of the sealed bag, allowing it to resume transportation along the conveyor.

Abstract: A multi-station filling apparatus and process for filling bulk containers while simultaneously enabling the deployment and staging of at least one empty container while at least one other container is being filled. The apparatus includes a container filling station operably positioned adjacent a substantially elevated filling chute, a container deployment station, a rotatable carriage and an automatic apparatus controller. The container deployment station is spaced apart from the container filling station so that an operator can attach an empty container thereat either prior to, or during, filling of another container at the container filling station--while avoiding physical exposure to any mechanisms, such as conveyors, associated with the container filling station. The rotatable carriage, which automatically rotates an empty container from the container deployment station toward and into the empty container filling station, includes an outer frame member and displaceable inner frame members.
