A method and apparatus for baling loose materials, such as waste material, includes a controllably moveable door assembly. In one embodiment, the door is adapted to open from an initial position to a final position such that the compacted bale can be ejected from the compaction chamber through the opening defined by the open door. In this embodiment, the leading edge portion of the door is moved to a final position in general alignment with the compacting ram platen such that bales of various sizes, including oversized bales, can be readily ejected from the baling apparatus. For example, the leading edge portion of the door can be moved into alignment with or rearward of the compacting ram platen. In another embodiment, the baling apparatus operates in a plug bale mode and includes a door which is urged against an at least partially ejected bale so as to securely hold the plug bale within the opening defined to the compaction chamber during the compaction of a succeeding bale. In particular, the door is partially closed until the speed with which the door is being closed is less than a predetermined speed. Once the speed with which the door is being closed falls below the predetermined speed, further closure of the door is halted and the plug bale is securely held within the opening due to the increased frictional forces provided by the partially closed door. |
