ABSTRACT:
A folded signature transfer and press stitcher delivery mechanism for receiving folded signatures draped over a signature conveying system, delivering the folded signatures to a press stitcher and returning the folded, stitched signatures to the signature conveying system includes an elongated first, inclined plow cooperatively associated with the gathering chain for slidably receiving folded signatures therefrom. The continuous propeller is adapted to push the folded signatures along the first inclined plow. A carriage is cooperatively associated with the first inclined plow for slidably receiving folded signatures therefrom. The carriage is disposed intermediate a pair of lateral offset continuous drive systems. A dual belt conveyor drive drives the continuous drive systems in the same direction at substantially the same velocity. The carriage is connected to the continuous drive systems such that it is driven in a preselected unchanging orientation about a closed path defined by the continuous drive systems. A press stitcher is disposed along the closed path of the carriage for stitching the signature carried by the carriage. A second inclined plow is disposed upon the closed path of the carriage downstream from the first plow and the press stitcher for slidably receiving the folded, stitched signatures from the carriage.
