Abstract

A system is described for receiving mixed mail pieces, for singulating the machinable mail including flats, and for culling all of the pieces into respective discrete categories for further processing. The system is characterized by an inherent freedom from jams and consequent mail damage and features a recycle loop which provides a continuous, substantially uniform output of machinable mail.
