ABSTRACT:
A bag filling apparatus including a clam-jaw spout having an inner liner and interior chute suspended beneath a hopper. The bottom end of the inner liner is pleated, and a pair of air jets disposed on opposing sides of the liner project a stream of air toward each concave side of the liner ensuring a uniform and repeatable fold and substantially dust-tight seal as the clam-jaw sections of the spout begin to close. The oval shape of the dust collectors and increased cross-sectional area of the ports and conduits increases the volume of air and amount of airborne particulate matter withdrawn from above the top of the bag without unduly increasing the flow velocity of the air through those ports, and without requiring separate air removal means disposed within the interior of the bag. Lateral movement of the bag gripping members toward the spout is controlled and limited by contact between the external side wall of the dust collectors and adjustable cushions disposed on the arms supporting the bag gripping members. The height of the bag gripping members relative to the bottom of the spout is adjusted using slots within the support plate, and the range of opening motion of the bag gripping arms is controlled by stops located on the support plate.
