ABSTRACT:
A bag filling and sealing machine includes a bag holder, a bag opening and filling station, and a sealing station. The bag holder holds wicketed bags in a manner that allows the bags to be easily torn from the holder. A funnel assembly successively opens each bag, tears the bag from the bag holder, fills the bag with material, and releases the bag to a grabber assembly. The grabber assembly engages the sides of the bag while the bag is attached to a funnel assembly and later pulls the sides of the bag away from each other so that the top of the bag is closed and ready to seal when the bag is delivered to a sealing apparatus. The grabber assembly moves in a manner so as to minimize the lost height when moving from the filling station to the sealing station.
