Abstract
A document handling apparatus includes a document transport buffering apparatus including drive belts and aligner belts. Each of the drive belts has a general continuous loop shape. The aligner belts are intermixed with the drive belts. Each of the aligner belts has a general continuous loop shape and a projection extending in a general cantilever fashion from the aligner belt. A first drive system is adapted to rotate the drive belts. A second drive system is adapted to rotate the aligner belts individually. The first and second drive systems are adapted to rotate the drive belts and the aligner belts such that a plurality of spaced stacks of documents are transported by the drive belts with one of the projections at a leading edge of each of the stacks and another one of the projections at a trailing edge of each of the stacks.
