Abstract
An automatic mail banding apparatus is disclosed in which mail is positioned in a stack in a mail receiving tray and is clamped to a movable portion of the tray. A rubber band applying assembly receives a rubber band at a position along the side of the tray, expands the band while axially aligning the expanded band with the stack of mail, moves the band axially toward the stack to surround the stack with the expanded band, and then releases the band around the stack. The movable portion of the tray pivots to move the stack to a new orientation while the stack of mail remains clamped to the movable portion of the tray, and a second band is applied to the stack by the band applying assembly in a transverse orientation to the first band.
