ABSTRACT:
A fabric bag for transporting bulk materials, especially granular materials, comprising four generally rectangular side walls, joined to and extending upwardly from a generally rectangular bottom wall; each side wall is joined to the adjacent side walls by a seam which includes two pleats formed inwardly of the side wall edges, the pleats being sewn together, leaving a terminal strip projecting into the bag interior. A lifting loop is located at the top of each seam; a terminal strip is folded over each lifting loop, the seam pleat is folded against one of the side walls, and the pleats, loop legs, terminal strips and side walls are fastened to one another by zig-zag anchor stitching extending from the tops of the walls at least to the bottoms of the lifting loop legs. Preferably, the bottom wall and two of the side walls are formed of a single U-shaped piece of material and the bottom wall is attached to the other two side walls of the bags by seams that are continuous with the side wall seams.
