ABSTRACT:
A bag filling machine, adapted to fill a plastic bag with a liquid product through a gland secured to the bag, comprises a conveyor for intermittently moving a series of the bags along a path. Adjacent pairs of the bags are connected together at a severable parting line, extending transversely relative to the path, and a cutting apparatus is adapted to sever the parting line. The apparatus comprises generally horizontally disposed first and second platens, spaced apart to define an opening therebetween, and extending transversely relative to the path of movement of the bags. Clamping bars are movably mounted above the platens to engage and clamp each adjacent pair of leading and trailing bags to the platens and to position the severable parting line over the opening defined between the platens. A cutter is slidably mounted in the apparatus for severing the parting line connecting the bags together. Each separated bag is then delivered by the conveyor to a filling station to have a liquid product dispensed therein, through the gland.
