The package enters the machine on a table top or mat top conveyor. The dual flights increment vertically to life the package off of the infeed conveyor and elevate it to the discharge elevation. The package can be pushed off the flights to form a "C" or a "Z" configuration. The machine can be equipped with a bi-directional flight sweep to discharge packages in either direction.
The lifting and lowering is accomplished with flights that are spaced vertically to accommodate both the shortest and tallest packages. The flights are spaced horizontally and are the proper width to accommodate both the widest and the narrowest packages. If the geometry of the package mix requires adjustability, the horizontal gap between the flights can be changed with the addition of an optional hand rotated lead screw. The flights can also be easily relocated on the carrying chain to accommodate taller packages.
