ABSTRACT:
Successive bags of material which are interconnected in a continuous web along the tops thereof by an integral tubular portion of the web, and which are individually open to the tubular portion but sealed from each other by seams extending along the adjacent sides thereof, are filled by an elongated filling pipe along which a tubular portion of the web is drawn. The underside of the pipe is provided with two spaced ports through which material is delivered into the successive bags, and in order to prevent material from accumulating above the adjacent seam portions of contiguous bags, these ports are alternately opened and closed in such timed relation with the feeding movement of the bags that each port is open when only one bag is passing thereunder and is closed when one of the seams is thereunder.
