Abstract
A flap opening apparatus wherein envelopes are sequentially conveyed past a jet nozzle, which delivers timed blasts of air to open the flaps of each envelope. A computer controller tracks the position of the envelopes by a shaft encoder, and activates the jet nozzle when each envelope is correctly positioned. The opened flaps of the envelopes are held in an open position by a plate so that mail materials may be inserted into the envelopes.
