Abstract

A stacking and feeding tray is described, which provides a fluctuating urging force upon a stack of mail. The fluctuating urging force provides a proper feeding of pieces of mail, such that a double feed of envelopes is essentially eliminated. The fluctuation in feed-in force is provided by a clutched drive, which is responsive to an optical sensing of the discharge of a piece of mail.
