摘要： A sheet separation device includes a sheet separator and a conveyor. The sheet separator separates a non-bonding portion of a two-ply sheet in which two sheets are overlapped and bonded together at a bonding portion of the two-ply sheet. The conveyor conveys the two-ply sheet toward the sheet separator while bending the two-ply sheet in a direction that intersects a conveyance direction of the two-ply sheet.

摘要： A sheet processing apparatus includes a plurality of roller pairs, a single driving force supply source, and a drive transmission mechanism. The plurality of roller pairs include a first roller pair, a second roller pair, and a third roller pair. The single driving force supply source supplies a driving force to the first roller pair, the second roller pair, and the third roller pair. The drive transmission mechanism transmits the driving force to the first roller pair and the second roller pair in a manner such that a rotation direction of the first roller pair is not switched even in a case in which a direction of the driving force is switched such that a rotation direction of the second roller pair is switched when the first roller pair and the second roller pair are driven by the driving force from the driving force supply source.

摘要： A sheet processing apparatus sandwiches a sheet media in a two-ply sheet in which two sheets are overlaid and bonded together at a portion of the two-ply sheet. The sheet processing apparatus includes a fixing device, a tray, and a roller. The fixing device applies heat and pressure to the two-ply sheet. The tray is disposed downstream from the fixing device in a conveyance direction of the two-ply sheet, to stack the two-ply sheet. The roller conveys the two-ply sheet vertically downward toward the tray after the two-ply sheet passes through the fixing device.

摘要： A sheet separation device separates a non-bonding portion of a two-ply sheet in which two sheets are overlapped and bonded together at a bonding portion of the two-ply sheet. The sheet separation device includes a separator, an abnormality detection device, and circuitry. The separator is configured to move to be inserted into a gap formed between the two sheets of the two-ply sheet. The abnormality detection device is configured to detect an abnormal state in which the gap larger than a predetermined size is not formed between the two sheets before the separator is inserted into the gap. The circuitry is configured to control movement of the separator based on a result detected by the abnormality detection device.

摘要： A sheet separation device separates a non-bonding portion of a two-ply sheet in which two sheets are overlapped and bonded together at a bonding portion of the two-ply sheet. The sheet separation device includes a winding roller and a gripper. The winding roller rotates and winds the two-ply sheet to separate the two-ply sheet. The gripper is disposed in the winding roller and configured to grip a gripped portion of the two-ply sheet at one end of the two-ply sheet without abutting a tip of the gripped portion at the one end of the two-ply sheet on a member.

摘要： An image forming system includes a sheet processing apparatus, a heat presser, an image forming apparatus, and control circuitry. The sheet processing apparatus separates a two-ply sheet in which two sheets are overlaid and bonded together at a portion of the two-ply sheet, and sandwiches a sheet medium between the sheets of the two-ply sheet. The heat presser heats and presses the two-ply sheet. The control circuitry performs a first mode to cause the sheet processing apparatus to sandwich the sheet medium, on which an image has been formed by the image forming apparatus, between the two sheets of the two-ply sheet and cause the heat presser to laminate the two-ply sheet, and a second mode to cause the heat presser to laminate a sheet set that includes the sheet medium sandwiched between the two sheets of the two-ply sheet by a user.

摘要： A sheet processing device includes a conveyor, a rotator, a separator, and control circuitry. The conveyor conveys a two-ply sheet in which two sheets are overlapped and bonded together at a portion of the two-ply sheet. The rotator winds the two-ply sheet. The control circuitry causes the conveyor to convey the two-ply sheet in a winding direction to wind the two-ply sheet around the rotator such that a sagging space is created in the two-ply sheet, and causes the separator to insert into the sagging space to separate the two-ply sheet into two sheets. The control circuitry causes the conveyor to convey the two-ply sheet in a direction opposite the winding direction before an insertion of the separator into the sagging space.

摘要： A laminating device inserts a sheet-shaped medium into a two-ply sheet in which two sheets are overlaid and partially bonded, and includes a loader, a fixing device, and control circuitry. The loader loads the sheet-shaped medium or a cleaning sheet. The fixing device laminates the two-ply sheet in which the sheet-shaped medium is sandwiched between the two sheets of the two-ply sheet. The control circuitry performs a cleaning mode of conveying a plurality of cleaning sheets from the loader to clean the fixing device. The cleaning mode is to convey a subsequent cleaning sheet of the plurality of cleaning sheets at a position different from a position of a preceding cleaning sheet of the plurality of cleaning sheets in a direction orthogonal to a conveyance direction of the plurality of cleaning sheets.
