Patent number: 10710834Abstract: A folding apparatus includes a folding device to fold a sheet bundle, an additional folding device, a conveyer, and control circuitry. The additional folding device includes a pressure roller disposed downstream from the folding device in a sheet conveyance direction and configured to press the sheet bundle after the folding device folds the sheet bundle and a sheet support member disposed opposite the pressure roller via the sheet bundle. The conveyer conveys the sheet bundle to a position at which the additional folding device presses the sheet bundle and hold the sheet bundle at the position. The control circuitry causes the additional folding device to perform additional folding processing on a first position of the sheet bundle, the conveyer to move the sheet bundle to a second position different from the first position, and the additional folding device to perform the additional folding processing at the second position again.Type: GrantFiled: December 20, 2018Date of Patent: July 14, 2020Assignee: Ricoh Company, Ltd.Inventors: Makoto Hidaka, Shinji Asami, Tomohiro Furuhashi, Takuya Morinaga, Tomomichi Hoshino, Yohsuke Haraguchi, Koki Sakano, Michitaka Suzuki, Akira Kunieda, Fumiharu Yoneyama
