摘要： A sheet laminator laminates a two-ply sheet and a sheet-shaped medium inserted in the two-ply sheet. The sheet laminator includes a sheet feeder, a multi-feeding detector, a fixing device, an ejection device, a purging portion, a passage switcher, and circuitry. The sheet feeder feeds the two-ply sheet. The multi-feeding detector detects multiple feeding of the two-ply sheet. The fixing device fixes the two-ply sheet by application of heat and pressure. The ejection device ejects the two-ply sheet that has been fixed by the fixing device. The purging portion is disposed at a position different from the ejection device. The passage switcher switches a conveyance passage of the two-ply sheet to the fixing device or to the purging portion. The circuitry conveys the two-ply sheet to the purging portion and retries sheet feeding with another two-ply sheet, in response to detection of multiple feeding of the two-ply sheet.

摘要： A sheet laminator includes a sheet lamination device, a heater, and circuitry. The sheet lamination device performs a sheet laminating operation on an object by application of heat and pressure. The heater heats the sheet lamination device. The circuitry changes between a first mode in which the heater constantly heats the sheet lamination device while the sheet lamination device is turned on and a second mode in which the heater starts heating the sheet lamination device in response to a request of the sheet laminating operation and stops heating the sheet lamination device after a given time has elapsed from completion of the sheet laminating operation. The circuitry adjusts the given time in the second mode.

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： 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.

摘要： A sheet processing device includes a conveyor, a rotator, a separator, and control circuitry. The conveyor conveys a sheet-shaped medium into a two-ply sheet in which two sheets are overlaid and partially bonded, and includes a drive roller and a driven roller. The rotator winds the two-ply sheet. The separator separates the two sheets of 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 to generate a space between the two sheets, and causes the separator to insert into the space between the two sheets to separate the two sheets. The drive roller and the rotator are disposed on a same side with respect to a sheet conveyance passage of the two-ply sheet, and the driven roller and the rotator are disposed on opposite sides with respect to the sheet conveyance passage.

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： An image forming apparatus includes a sheet separation device, a first sheet feeder, a second sheet feeder, an image forming device, and circuitry. The sheet separation device is configured to separate 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 first sheet feeder is configured to feed the two-ply sheet. The second sheet feeder is configured to feed an inner sheet to be inserted between the two sheets. The image forming device is configured to form an image on a surface of the inner sheet. The circuitry is configured to cause the first sheet feeder to feed the two-ply sheet, perform a sheet separating operation on the two-ply sheet and cause the second sheet feeder to start feeding the inner sheet before completion of the sheet separating operation on the two-ply sheet.
