Multiple pass document sorting machine utilizing automatic sweeping and multiple recirculation trays

摘要

A method for increasing the throughput of a multiple pass document sorting device that sorts documents into a plurality of output holders by automatically displacing the sorted documents within the receiving areas of each output holder into recirculation holders. The recirculation holders are then sequentially aligned with the input holder and the associated document cluster is transferred to the input holder. In this manner a next sorting pass may be initiated, using documents from the recirculation holders, with documents being sorted into the available output holders.
