ABSTRACT:
In order to accommodate either a loose lift of signatures or, alternatively, a signature log for the purpose of stream feeding a supply of signatures to a packer box on a binding line in an effective and efficient manner, a signature stream feeding apparatus is disclosed which includes an upstream conveyor, an intermediate conveyor, and a down stream conveyor. The upstream conveyor receives and supports signatures in a generally upright position on the fore edges or backbones thereof, and it is downwardly inclined relative to the horizontal in the direction of signature travel therealong. The intermediate conveyor then receives the signatures from the upstream conveyor and conveys them toward the packer box, and it is inclined upwardly and away from the upstream conveyor in the direction of travel of the signatures therealong. The downstream conveyor finally receives the signatures from the intermediate conveyor and conveys them toward the packer box, and it extends between the packer box and the intermediate conveyor. By utilizing an upstream conveyor, an intermediate conveyor, and a downstream conveyor having these characteristics, the conveyors may be controlled to transform the signatures into a shingled stream at the intermediate conveyor and into a thinner shingled stream at the downstream conveyor at a point in advance of the signatures reaching the packer box on the binding line.
