ABSTRACT:
An automatic bag filling machine employs a reduced pressure or a vacuum within a bag enclosing shroud to draw powdered material into either valved bags or vapor barrier bags in a series of increments to fill the bags with a relatively compacted powder. The shroud has movable liner assembly for adjustably enclosing bags of various size. A novel filling spout and a vapor barrier spout carrier by the shroud each have an expandable boot member to seal the mouth of the bag on the spout to preclude seepage of powdered material from the bag interior during filling. A filter tank connected to the machine reduces the discharge of powdered material into the surrounding atmosphere, and allows waste material to be reclaimed. Valves for controlling vacuum imparted to the shroud chamber, venting the bag interior, powdered material flow, and relief to atmospheric pressure of the shroud interior, are operated in proper sequence to fill the bag.
