Abstract
Methods and apparatuses for filling flexible receptacles or bags with bulk or particulate material is provided. In one aspect, an automatic sand bag filling apparatus is disclosed which includes a bulk fill channel which may be placed within the interior of each bag to be filled. The filling apparatus may have a metering device for providing the desired amount of bulk material to the fill channel. The fill channel may be moveable along a fixed path for engaging and advancing a series of interconnected bags. Articulating spreader bars may be provided to support the bag during filling. In one embodiment, the filling apparatus is mounted on a trailer assembly and includes a reservoir for storing the bulk sand. The sand may be transferred from the reservoir to the filling apparatus using augers, conveyors, etc. A preferred construction of a series of interconnected sand bags and a method of making a series of interconnected bags is also disclosed.
