Abstract: A transport section for a document-handling machine includes a pair of horizontally-oriented feed belts which act in conjunction with segment flaps on a segmented, vertically-oriented feed belt to deliver groupings of mail items in a feeding direction. A set of horizontally-oriented take-away belts receives documents from the horizontally-oriented-feed belts and transports them at an accelerated speed with respect to the horizontally-oriented feed belts. The accelerated speed of the take-away belts is used to compensate for the acceleration of each given document by the tips of the flaps as the flaps round the corner at the end of their run.

Abstract: A transport mechanism for transporting flat documents placed therein on edge uses a horizontal conveyor belt to convey stacks of documents on-edge in a first feeding direction. Tapered rollers with a feeding direction perpendicular to that of the conveyor belt are provided at the end of the conveyor for feeding the documents in a direction perpendicular to the first feeding direction. The use of tapered rollers allows a gradual, rather than sudden, perpendicular velocity to be imparted to the documents, thereby relieving strain on the roller drive mechanism, the rollers themselves, and the documents at high machine throughput speeds. The use of tapered rollers also provides a shingled output of documents, which allows a stripping station down-line from the feeder to strip the documents with fewer misfeeds and less strain.

Abstract: A bin tray is provided for supporting a mail bin which receives documents from a document processing machine. The bin tray is slidable so that it may be stored underneath the table when not in use and is lowerable and removable so as to facilitate access to the underside of the document processing machine. This is accomplished by use of a tray assembly which is removably and rotably attached to two support rods running underneath the table in a direction perpendicular to the feeding direction of the documents as they enter the bin. The support rods are generally vertically oriented with respect to each other and provide support for a housing containing a slidable bin tray.
