ABSTRACT:
A method and apparatus for filling bulk bags employ a filling tube assembly comprising an inner tubular wall having an auger disposed therein for forcing powdered material into a bulk bag and packing it densely therein, and an air-permeable outer tubular wall disposed coaxially about the inner tubular wall to define an exhaust chamber so that air in the material may be drawn inwardly through the outer tubular wall when the filling tube assembly is immersed in the material.
