International Classification:

B65H 39/10

US Classification:

271301, 271304, 271186, 399364

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.

International Classification:

B65H 29/00

US Classification:

271186

Abstract:

A sheet inverter apparatus improves the handling capabilities of high speed printers and copiers. The sheet inverter apparatus includes a rotatable support having an axis of rotation and at least first and second arms radiating outwardly from the axis of rotation. First and second nip assemblies are is mounted to the first and second arms respectively. The support is rotatable to adjust positions of the first and second nips about the axis of rotation. Advantageously, with this arrangement, the support is adjustable so as to permit the first and second nips to receive sheets of paper at one location, be positionally adjusted with the sheets of paper moving therewith, and located at a second location so as to deliver the paper to an outlet feed path. This positional adjustment allows for inversion of the paper.

US Classification:

271225, 271186

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.
