An apparatus for continuously producing a particulate filled bag or barrier. The apparatus includes a frame having terrain engaging members, such as runners. A wound coil of sheet material is mounted on the forward end of the frame, and located to the rear of the coil is an open bottom hopper that contains a partic- ulate material, such as sand or gravel. The sides of the hopper are composed of spaced double walls and the rear surface of the hopper is formed with an outlet. The sheet material is unwound from the coil and continuously folded into a generally U-shape by a pair of lower roll- ers and two pair of upper rollers, which are mounted on the frame forwardly of the hopper. The bottom surface of the folded sheet extends across the open bottom of the hopper, so that the particulate material will be in direct contact with the bottom surface, while the side surfaces of the folded sheet extend upwardly in the spaces between the double side walls of the hopper. The weight of the particulate material resting on the bottom surface of the folded sheet will hold the sheet against the terrain as the frame is moved forwardly, and the folded sheet containing the particulate material is discharged from the outlet in the hopper and passes between a pair of converging side members to compress the particulate material. The upper edges of the side sur- faces of the folded sheet are then brought together and connected to provide a bag containing the particulate material.
