Abstract
Provided herein is sheet inverter apparatus which includes a diverter gate which diverts the sheet to one of at least two paths, a first paper path, and a second paper path. The first and second path each include a rotatable nip assembly, the rotatable nip assembly including a nip drive roll and a nip idler roll positioned so as to define a nip therebetween, the nip serving as a rotatable axis around which the nip drive roll and the nip idler roll rotate to invert the sheet.
Claims12
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.

A document processing device comprising:
- a sheet inverter including:
- a diverter gate which selectively directs a sheet to 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;
- and,
- 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,
- a paper feed path positioned to direct paper into said inverter;
- and
- a paper outlet path, spaced from said paper feed path, positioned to receive paper from said inverter, and forward to a next stage in the document processing process.
