Abstract: A method and system for converting mail between trays in a multiple pass mail sorting system using a plurality of different tray types. Mail from a first type of tray is unloaded and stacked along with mail from other trays to form a large stack. The large stack of mail is then broken down into smaller stacks which are transferred to one of several outputs where the mail is loaded into different types of trays.

Abstract: The present invention relates to a tray transfer system (TTS). This system is designed to automatically transfer trays of mail between dollies and conveyor belts. The TTS is an efficient method for shipping, moving, storing, loading, and unloading mail trays. It allows mail-processing centers to physically and temporally separate the process of sorting mail and the process of moving mail into automation compatible trays (ACT).

Abstract: An apparatus for the preparation of bundled mail for subsequent processing is provided. The apparatus includes a first flat surface, proximate to a top end, having a downward angle with respect to a horizontal plane, and a second flat surface, abutting the first flat surface and proximate to a bottom end, having a downward angle with respect to the horizontal plane that is greater than the first flat surface angle. A bottom corner, formed from a first supporting sidewall and a second supporting sidewall, has an opening adapted to receive a corner portion of a mail bundle.

Abstract: Preferred embodiments pertain to a carrier for carrying side-by-side stacked mail. The carrier preferably includes: a floor upon which side-by-side stacked mail can be supported; a rear wall having spaces configured to receive a pusher inserted behind side-by-side stacked mail in the carrier; and a front wall movably mounted between a side-by-side stacked mail retaining position and a side-by-side stacked mail releasing position in which stacked mail can slide with respect to the floor and past the stacked mail retaining position.
