A pair of conveyance rollers are arranged for signatures. The signatures is conveyed through the pair of conveyance rollers to a stacking unit while being sandwiched from both sides thereof between the pair of conveyance rollers. In response to passage of a signature for a sheet stack through the pair of the conveyance rollers, the conveyance rollers is switched from conveyance rotation to intermittent rotation to cause the pair of the conveyance rollers to keep the signatures for a next sheet stack from being conveyed to the stacking unit. In response to the stacking unit becoming ready to receive the signatures for the next sheet stack, the conveyance rollers is switched from the intermitted rotation or the stop to the continuous rotation to cause the pair of the conveyance rollers to convey to the signatures to the stacking unit.

An apparatus and method for forming a plurality of individually folded and rolled wipe products, which allows for multiple individually folded and rolled wipe products to be processed concurrently, and which maintains moisture in the wipe product during manufacturing.

A device for folding web material in a plant for producing layered composite articles includes: a first guide defining a feeding plane for feeding a web material; a second guide positioned downstream of the first guide and defining a receiving plane for receiving the web material, wherein the receiving plane is substantially orthogonal to the feeding plane. A folder is arranged between the first guide and the second guide and includes an elongated edge having a first end close to the first guide and a second end close to the second guide. The elongated edge is extended from the first guide towards the second guide in the receiving plane and away from the feeding plane, in order to progressively move an intermediate portion of the web material away from the feeding plane and fold in two the web material as it travels from the first guide towards the second guide.

A sheet processing device includes a first conveyance passage, a first conveyor, a second conveyor, a folder, a second conveyance passage, and circuitry. The circuitry is configured to (1) cause the first conveyor and the second conveyor to convey the sheet nipping the sheet to warp the sheet between the first conveyor and the second conveyor, (2) guide the warped sheet to form a first fold on the sheet by the folder and circulate the sheet to the first conveyance passage, (3) cause the first conveyor and the second conveyor to convey the sheet while nipping the sheet again to warp the sheet between the first conveyor and the second conveyor, (4) guide the warped sheet to form a second fold on the sheet by the folder, and (5) cause the second conveyor to convey the sheet with the first fold and the second fold.

A fabric folding machine contains: a body and a limiter. The body includes an external housing, an internal housing, and a connection portion. The external housing has a first peripheral fence, a second peripheral fence, and two third peripheral fences, wherein the internal housing is disposed in the external housing, and between the external housing and the internal housing is defined a through hole which has a first segment and a second segment, a height of the first segment is more than that of the second segment, and a width of the internal housing gradually decreases from the first segment to the second segment. The first peripheral fence has a first orifice defined, and the second peripheral fence has a second orifice and two guiding apertures. The limiter includes a sheet and a protrusion, and the sheet has two openings defined thereon.

An image forming apparatus includes an image forming unit, an input unit configured to receive input of folding unit information specifying either one of a first sheet folding unit and a second sheet folding unit, and a control unit configured to selectively perform a first mode and a second mode based on the folding unit information, the first mode being a mode in which the image forming unit forms the image on the sheet such that an orientation of the image becomes a first direction, the second mode being a mode in which the image forming unit forms the image on the sheet such that the orientation of the image becomes a second direction inverted from the first direction.

A paper sheet S is intermittently transported by a transport mechanism 6 and each processing unit 7, 8 operates while the transport mechanism pauses the transport operation. An information acquisition unit 9 obtains paper information from the paper sheet. A control unit 10 stores the paper information of the paper sheet to be processed for each processing unit, updates the data of the memory in a manner such that the paper information of the paper sheet associated with the previous processing unit is associated with the next processing unit every time the transport mechanism transports, and configures the settings of each processing unit for the next processing operation based on the paper information every time the processing operation of the processing unit is completed.
