  • Patent number: 6631900
    Abstract: An apparatus that can rotate a sheet 180° or invert the sheet, if required, includes a horizontal cylinder. The apparatus includes a horizontal cylinder. A front image output sheet wraps around the horizontal cylinder (turning counter-clockwise), entering the cylinder from the bottom. The cylinder then rotates 180° with the wrapped sheet. Continued counter-clockwise rotation of the cylinder will now unwrap the sheet from the cylinder and drive it away from the cylinder. In order to accomplish inversion, a deflector is raised in front of the cylinder. A sheet is directed over the top of the cylinder by the deflector as the cylinder turns clockwise. The sheet wraps around the cylinder and thereafter, the cylinder is rotated counter-clockwise resulting in the sheet exiting the cylinder at the bottom after having been inverted.
