Abstract
An improved bulk bag unloading station is disclosed. In its simplest form, the improvement is comprised of a movable dispensing spout which is attached to and depends from an outlet of the bulk bag. As material is dispensed through the spout, the moveable spout will cause the bulk bag to elongate. Through movement of the spout, the bag is continually elongated to continually urge the flow of material from the bulk bag and to promote full discharge of the material from the bag. In the preferred embodiment, a lift and hold apparatus is provided to position the spout during initial attachment to the outlet of the bag.
