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.

Abstract: A materials handling system includes a materials processing subsystem with a first materials transport path having a curved portion along which materials are transported and a second straight materials transport path. A diverter is connected between the processing subsystem and the first material transport path and the second material transport path. One of the first materials transport path and the second materials transport path is positioned above the other materials transport path. The diverter is operable to selectively divert materials from the materials processing subsystem to be transported by one of said first and said second transport paths. The materials processing subsystem may be an insertion subsystem for inserting materials into envelopes to form mailpieces of a first type and mailpieces of a second type.

Abstract: A materials handling system includes a feeder station having a plurality of material feeders and an insertion subsystem. Each of the plurality of feeders are connected to a common material transport path. A first material transport path is connected to the common material transport path and to the insertion subsystem. A second material transport path is connected to the common material transport path and to the insertion subsystem. A third material transport path is connected to the first material transport path and to said insertion subsystem. The second material transport path may include a materials processing subsystem such as a folder subsystem. The common materials transport may include a pre-fold accumulator transport having a pre-fold accumulator gate. A first diverter may be provided to selectively divert materials being transported by the pre-fold accumulator transport to the first or to the second material transport.
