ABSTRACT:
A method and apparatus for automatically forming and filling sandbags. The apparatus has an excavator for obtaining fill material for the sandbags. The fill is transported from the excavating means to a hopper which dispenses the proper amount of fill into a bag. The bag is formed from two webs of bag forming material which are joined along their edges to form a tube. A clamping, cutting and stitching mechanism clamps and cuts the tube, forming the tops and bottoms of the sandbags. A stitching mechanism stitches the cut top and bottom. The clamping, cutting and stitching mechanism is operated by a hydraulic piston which pulls the sandbag web material from rolls and moves the web from the filling area to the discharge area. A conveyor system moves the formed sandbags from the device for stacking or use. The entire apparatus is mounted on a tractor-type frame so that it can be transported from one location to another.
