Apparatus for filling bags and providing completely controlled handling of bags from filling through their movement to a bag closing station. A pair of elongated forming bars supported for up and down movement and traversing movement between a bag filling hopper and a laterally spaced bag closing station grip, flatten, and assist in forming gusseted bags after filling while the bags are still clamped on a filling spout, and thereafter controllably lower the filled bags to a conveyor and support the bags on the conveyor in traversing movement to a final bag closing station. A pair of gusset arm assemblies supported for lateral shifting movement on opposite sides of a filling spout each include a pair of gusset clamping fingers which are disposed inside of the mouth of a bag during filling. The clamping fingers are actuated in a predetermined sequence to hold and form the gusset pleats of the bag while permitting the bag to be opened over its full width during the filling operation.
