Abstract
A method and apparatus for high speed traying of mail pieces includes a tray filling head assembly, a tray fill conveyor assembly, and a tray feed assembly. A continuous stream of mail pieces are fed into the tray fill head assembly, which controllably moves the mail pieces one at a time into a postal carrier tray. The postal carrier trays are selectively staged for filling and automatically ejected when filled by the tray fill conveyor assembly. The tray feed assembly feeds the trays to the tray fill conveyor assembly. When a filled tray is being exited and an empty tray is being staged for filling, the tray fill head assembly buffers the mail pieces so that the continuous stream of mail pieces is not interrupted.
