摘要： A sheet processing device (1, 1A) is configured to separate a two-ply sheet (PJ, S) in which two sheets (P1, P2) are overlapped and bonded together at one end of the two-ply sheet. The sheet processing device includes a first sheet feeder (2, 11) configured to feed the two-ply sheet (PJ, S), a second sheet feeder (3, 12) configured to feed an inner sheet (PM) to be inserted between the two sheets in a state in which the two-ply sheet is separated, and a controller (500, 500A) configured to cause the first sheet feeder to feed the two-ply sheet, perform a sheet separating operation on the two-ply sheet to separate the two-ply sheet, and cause the second sheet feeder to start feeding the inner sheet before completion of the sheet separating operation.

摘要： A sheet separation device (1) includes a sheet separator (19) and a conveyor (36). The sheet separator (19) separates a non-bonding portion of a two-ply sheet (PJ) in which two sheets (P1, P2) are overlapped and bonded together at a bonding portion of the two-ply sheet (PJ). The conveyor (36) conveys the two-ply sheet (PJ) toward the sheet separator (19) while bending the two-ply sheet (PJ) in a direction that intersects a conveyance direction of the two-ply sheet (PJ).

摘要： A sheet separation device (1) separates a non-bonding portion (B) of a two-ply sheet (PJ) in which two sheets (PI, P2) are overlapped and bonded together at one end (A) of the two-ply sheet (PJ). The sheet separation device (1) includes a separator (16, 17) that includes a first separator (16) and a second separator (17). The first separator (16) is inserted into a gap (C) between the two sheets (PI, P2) of the two-ply sheet (PJ). The second separator (17) is inserted between the two sheets (PI, P2) at another end (B) of the two-ply sheet (PJ) opposite to the one end (A) of the two-ply sheet (PJ) and moves in a width direction of the two-ply sheet (PJ), after the first separator (16) is inserted into the gap (C) and relatively moves from the one end (A) to said another end (B).

摘要： A sheet processing device (100) inserts a sheet-shaped medium into a two-ply sheet in which two sheets are overlaid and partially bonded. The sheet processing device includes a controller (500) to execute a single insertion mode in which one sheet-shaped medium is inserted into the two-ply sheet and a multiple insertion mode in which a plurality of sheet-shaped media are inserted into the two-ply sheet along a conveyance direction. The controller (500) inserts the one sheet-shaped medium into the two-ply sheet in the single insertion mode and the plurality of sheet-shaped media into the two-ply sheet in the multiple insertion mode, with the two-ply sheet being stopped.
