Abstract
A hopper loader apparatus for transferring and separating individual signatures of sheet material from a vertically aligned, parallelepiped shaped stack of such signatures. The separated, individual signatures may then be subjected to handling operations such as stapling or stitching. The hopper-loader has a first, downwardly inclined, planar conveyor, a second upwardly inclined, planar ramp conveyor which separates individual signatures from the stack and moves the signatures at a faster speed than the first conveyor. An included angle is formed between the first and second conveyors which ranges from about 125.degree. to about 145.degree. . Signatures are delivered to a pocket having spaced side walls and having a floor comprising a third intermittent indexing conveyor which sequentially moves the individual signatures away from the second conveyor and makes them available to stapling or stitching equipment.
