Abstract: A method and apparatus for loading bulk materials is disclosed. The apparatus of the present invention comprises a track and a frame movable on the track between a retracted and extended position. A first plate is movably mounted on the frame, and a ram is operably connected to the first plate for moving it between a retracted and extended position. A feeder may also secured to the frame. In operating a press such as the one disclosed, the frame and plate are moved within the container, a compressible material is transferred into the container, the compressible material is compressed, and the frame and plate are moved to a position outside the container. The steps of transferring compressible material into the container and compressing it may be repeated as desired. The frame may also be equipped with a second plate in which case one plate may be compressing material while additional compressible material is simultaneously being transferred into another portion of the container.
