Document Sort Machine Having Dual Feeders

摘要

A document sorting machine having dual feeders which feed documents onto common tiers of sort pockets form each end of the machine. The machine includes an induction buffer section which prevents a document already in the transport on a particular tier from colliding with a document being fed into the same transport by a different feeder. Also, the machine includes a serpentine piggy-back unit which can stack consecutive documents going to the same sort pocket.
