Abstract: A baler for the production of parallelepiped or slab-shaped bales is provided with a baling chamber whose cross section can be easily repositioned in height by servo motors that operate to adjust one part of the baling chamber relative to an overlapping second part. Corresponding adjustments can be made to the position of a driver for the baling piston, which itself is constructed to include separate telescoping parts. In addition, the needle assembly is provided with needle carrying arms that are mounted for movement with the movable part of the baling chamber.

Abstract: An apparatus for in-situ baling of trees is provided. The apparatus includes a first frame which supports a rotatable second frame. A tree trunk is inserted into the first and second frames. The second frame is rotated by a motor as the frames are elevated toward the top of a tree. During elevation, string is dispensed from a cannister on the second frame, baling the tree. The dispensed string is then secured completing the operation.
