Apparatus for the continuous production of a particulate filled barrier

An apparatus for producing a continuous particulate filled bag, comprising a frame having a forward end and a rear end, terrain engaging means on the frame for riding on terrain as the frame is moved thereon, a hopper mounted on the frame and containing a particulate material, said hopper having an open bottom directly exposed to the terrain, said hopper having a pair of side walls and a rear wall, said hopper having an outlet in a lower portion of said rear wall, each side wall including an inner wall section and an outer wall section spaced from the inner wall section to provide a clearance therebetween, folding means for forming a sheet of flexible material into a generally U-shaped configuration to provide a folded sheet, said folded sheet having a bottom surface and a pair of spaced generally parallel side surfaces, said bottom surface being disposed across the open bottom of the hopper and in contact with the terrain, and said side surfaces being disposed in the respective clearances, said particulate material in the hopper being in direct contact with the bottom surface of said folded sheet and being out of contact with the side surfaces of the folded sheet, means for moving the frame and the folded sheet relative to each other to cause the folded sheet containing said particulate material to be displaced from the outlet in said hopper, and means on the frame and located rearwardly of the hopper for moving the upper edges of the side surfaces of the folded sheet into generally proximate relation whereby said upper edges can be attached together to provide a continuously formed particulate filled bag.
