Abstract
An improved rotator/translator apparatus includes a set of drive rolls driven by a pair of rotator discs. Idler rolls are positioned above each drive roll and spring loaded to provide the required normal force to drive sheets in any direction required. A pair of magnetic couplings couple the drive rolls with the idler rolls. The magnetic couplings are spaced with about a 5 mm gap to allow sheets to pass therethrough. The couplings allow the idlers and the drive rolls to stay aligned. Thus, driving media, registering media and rotating media in a transport is obtained, but with no relative motion or slip between the drive rolls/idler rolls and the media and a larger nip surface area, thereby eliminating marking of certain media.
