A mailpiece fabrication system including a source for providing sheet material having mailpiece data printed thereon. The mailpiece fabrication system further includes at least one spatial positioning device adapted to direct the sheet material along one of two fabrication paths. Each fabrication path includes a fabrication assembly for producing one of at least two mailpiece configurations. In one embodiment, the spatial positioning device includes an orbiting nip roller for changing the elevation of the sheet material while, furthermore, providing an accurate and controlled mechanism for stacking and aligning sheet material to produce a flats mailpiece. In another embodiment, the spatial positioning device includes a routing roller in combination with the orbit nip roller to change the orientation of the sheet material. The routing roller is employed to change the direction of the sheet material relative to the feed path. Deformation binding mechanisms may be employed to form and seal various bind lines of the finished mailpiece.
