A folding machine for folding fiber products and fiber products formed and stacked thereby are disclosed. The folding machine includes two folding devices, each of which includes a cutting device, a delivery wheel, a folding-line wheel, a platen wheel, and a folding wheel. The cutting device cuts the fiber product and transports the cut fiber product to the delivery wheel. The folding-line wheel is adjacent to the delivery wheel for making a first folding line on the fiber product carried by the delivery wheel, and then the platen wheel folds the fiber product along the first folding line. Subsequently, the once-folded fiber product is transported to the folding wheel. The folding wheels of the two folding devices are adjacent to each other and are used to fold the fiber product passing therethrough for a second time, and thus fiber products with three folds are formed.

A document feeder includes a document placement member that has a placement surface, a sucker that has a suction surface on which a part of a document placed on the placement surface is sucked and sucks air from a space formed between the document placement member and the suction surface, a blower that blows air into the space, and a paper feeder that conveys the document in a conveyance direction along the placement surface, wherein the suction surface is inclined relative to the placement surface such that the space is narrower toward the upstream side in the conveyance direction.

A sheet processing apparatus includes a folding device to fold a sheet and a fold-enhancing device to press a folded portion of the sheet folded by the folding device to perform enhanced folding processing on the sheet whose trailing edge has exited the folding device.

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.

A sheet processing apparatus includes a rotatable pressing member, a guide, and a contact member. The rotatable pressing member includes a pressing portion that is disposed in a predetermined range in a rotation direction of the pressing member to press a folded portion of a sheet. The guide is disposed opposite the pressing member. The contact member contacts the guide and is rotatably disposed at at least one end of the pressing member in an axial direction of the pressing member.

The invention provides a sheet material dispenser and more particularly a dispenser for storing and dispensing a compact stack of folded tissue products. The compact stack of folded tissues may be secured by the tension of a pair of opposed side panels having a generally elliptical shape. The elliptically shaped side panels result in a rigid, resilient frame-work such that the dispenser has sufficient resiliency to maintain its shape even after a portion of the folded tissue products have been dispensed.
