ABSTRACT:
Two shingled streams of signatures are stacked independently of each other in separate stacking bins that are aligned vertically one above the other and also vertically aligned with the collection bin of a re-feeder. The collection bin is replenished periodically by stopping the shingled streams and unloading the contents of the lower and upper stacking bins to form a combined stack of signatures in the re-feeder collection bin. Signatures in the re-feeder collection bin are delivered by an out-feed conveyor belt in a single reshingled stream of signatures to an in-line processing station. In an alternative embodiment, the stacking bins are laterally separated with respect to each other for separately stacking signatures from two incoming shingled streams that are being output from separate web presses or other independent sources. The incoming signatures are separately stacked and the stacks are periodically unloaded onto separate stacking tables on laterally opposite sides of a common re-feeder. The signature stacks are separately delivered at different times into the re-feeder collection bin, thereby forming a combined stack of signatures that are subsequently reshingled into a single running stream.
