Abstract
An improved rotator/translator mechanism includes multiple thin discs that mate with an idler roll to distribute nip pressure and spin at different rotational velocities to produce the same linear velocity at the nip and thereby reduce marking on certain media.
Claims5
A finisher transport module having a rotator and translator device for use in controlling the orientation and alignment of sheets passing through said finisher transport module in a predetermined paper path, comprising:
- a pair of closely spaced rotating disc sets positioned such that said sheets pass over upper edge portions thereof of the pair of said closely spaced rotating disc sets that are orthogonal with respect to said predetermined paper path when passing thereover in said predetermined path;
- and
- wherein each of said rotating disc sets includes at least two concentric discs with one of said at least two concentric discs positioned for rotation within a circumference of the other of said at least two concentric discs, and wherein each disc of said rotating disc sets has a different radius with a first disc of each rotating disc set being mounted on a motor shaft that is drivingly connected to a motor to rotate the first disc, and a second disc of each rotating disc set configured to rotate around its corresponding motor shaft and being drivingly connected to an external shaft, and wherein each external shaft of each rotating disc set includes two gears mounted thereon.
A method for controlling the orientation and alignment of sheets passing through a finisher transport module that includes a rotator and translator device with the sheets being conveyed in a predetermined paper path, comprising:
- providing a pair of closely spaced rotating disc sets positioned such that said sheets pass over upper edge portions thereof of the pair of said closely spaced rotating disc sets that are orthogonal with respect to said predetermined paper path when passing thereover in said predetermined path;
- and
- providing each of said rotating disc sets with at least two concentric discs with one of said at least two concentric discs positioned for rotation within a circumference of the other of said at least two concentric discs, and wherein each disc of said disc sets has a different radius with a first disc of each rotating disc set being mounted on a motor shaft that is drivingly connected to a motor to rotate the first disc, and a second disc of each rotating disc set configured to rotate around its corresponding motor shaft and being drivingly connected to an external shaft, and wherein each external shaft of each rotating disc set includes two gears mounted thereon.
