ABSTRACT:
A bag filling machine, adapted to fill a plastic bag with a liquid product through a gland secured to the bag, comprises a filling head including a fill tube having a piston reciprocally mounted therein for selectively filling the bag with the product. A replaceable nozzle is positioned at an outlet of the fill tube and is releasably attached thereto. An annular seal is secured on a distal end of the nozzle for engaging an annular bearing surface of the gland in sealing contact therewith. Thus, nozzles, having seals and flow passages of varied diameters, may be selectively attached to the fill tube to accommodate glands having varied diameters.
