Abstract:
1. A sheet inverter apparatus comprising: a diverter gate which selectively directs a sheet to one of at least a first path and a second path; a first rotatable nip assembly disposed along said first path, said first rotatable nip assembly including a first nip drive roll and a first nip idler roll positioned so as to define a first nip therebetween, a first axis passing through said first nip around which said first nip drive roll and said first nip idler roll rotate, a second rotatable nip assembly disposed along said second path, said second rotatable nip assembly including a second nip drive roll and a second nip idler roll positioned so as to define a second nip therebetween, a second axis passing through said second nip around which said second nip drive roll and said second nip idler roll rotate, wherein, said first path includes a first pathway for directing a sheet to said first rotatable nip assembly and a second pathway for receiving the sheet after passing through said first rotatable nip assembly, said first rotatable nip assembly being configured to rotate with a sheet engaged in said first nip so as to invert the sheet between said first pathway and said second pathway, wherein, said second path includes a third pathway for directing a sheet to said second rotatable nip assembly and a fourth pathway for receiving the sheet after passing through said second rotatable nip assembly, said second rotatable nip assembly being configured to rotate with a sheet engaged in said second nip so as to invert the sheet between said third pathway and said fourth pathway.
