Abstract
A method and apparatus for folding inserts by inverting the insert sheet after the first fold is made and reintroducing the folded insert sheet into a first buckle chute from the opposite end. The second fold is then made in a second buckle chute which results in either a bottom address or a middle address appearing on the folded insert in a manner that the address will appear through the window of the envelope.
