Abstract

A dual path, single reversing roll inverter driven by a single actuator includes a single reversing roller with two, diametrically opposed idler rollers. The configuration of the reversing roller and idler rollers forms a first nip and a second nip that are alternately used to accept sequential sheets from a paper path. The first and second nips discharge the sheets into respective first and second inverting paths. A method for inverting sheets using the dual path, single reversing roll inverter includes rotating the roller in a first direction to direct a first sheet through the first nip. The roller is then rotated in a second direction opposite the first direction to direct the first sheet from the first nip and into the first inverting path and to simultaneously direct a second sheet into the second nip. A gate alternately directs the sequential sheets into the first and second nips.
