Abstract: A device for inverting a sheet along a path in an electric photographic printing machine. A gateless sheet inverter is provided in which a curved portion of a sheet path branch intersects a second portion of the sheet path to form a curved inverter throat. As the sheet is driven from the curved branch portion of the path into the throat portion the beam strength of the sheet causes the trail edge of the sheet to flip toward a second nip leading to the second sheet path. A pair of reversing rolls captures the lead edge of the sheet to be inverted and then reverses to drive the sheets out of the second nip formed by a tri-roll arrangement. A sheet having a radius of curvature equal to or greater than the radius of curvature of the throat will be guided along the throat baffle and fed through the second nip. To further assist in assuring the trail edge flips to the second sheet path an air knife can be added at the intersection of the path branches to assist in moving the trail edge into the second path branch. A fixed deflector can also be added and configured so that the trail edge of the sheet is guided into the second branch of the sheet path to increase the latitude of sheet curvature that can be handled by the device, the deflector further having a curved radius on the portion of the deflector contacting the sheet so that coated sheets are not damaged.

Abstract: A reproduction machine adapted for producing copies of an original on both sides of a copy sheet and forwarding the finished copy to a collator. An inverterreverser is employed which allows single-sided copy to a waiting station for subsequent processing to allow copying on the reverse side of the sheet to produce duplex copies, and for inverting duplex copies prior to delivery to the collator to provide the required sheet orientation in the collator. A sheet buckle control device cooperates with the inverter-reverser to insure that papers of widely different paper sizes, weights and stiffness will be inverted during the inverting stage of delivery of duplex copies.

Abstract: PROBLEM TO BE SOLVED: To reduce cost and to enhance the reliability of a device by eliminating a large number of moving parts in a sheet reverser or feeder.
SOLUTION: The sheet reverser 20 includes a curved sheet passage 26. A sheet driver 24 is disposed to receive a sheet along the sheet passage, leads in the sheet and reverses the moving direction of the sheet. An outlet passage 18 is disposed to receive the sheet from the sheet driver. A reverser passage 18 is disposed to receive the sheet from the sheet driver. A first immobile part 23 for leading the sheet toward the outlet passage is disposed at the starting point of the outlet passage, and a second immobile part 25 for leading the sheet toward the reverser passage is disposed at the starting point of the reverser passage. The sheet is fed to the outlet passage or the reverser passage depending on how far the sheet is led in by the sheet driver.
