摘要： A sheet separation device (100) to separate a two-ply sheet in which two sheets are bonded together at a portion of the two-ply sheet includes a rotator (109), a conveyor (113) configured to convey the two-ply sheet to the rotator (109), and means for winding (110,111,112,T1,T2; 117; 119), around the rotator (109), the two-ply sheet conveyed by the conveyor (113), to create a difference in winding circumferential length between the two sheets and separate the two sheets. The conveyor (113) conveys the two-ply sheet with a bonded portion of the two-ply sheet being an upstream end or a downstream end of the two-ply sheet in a conveyance direction of the two-ply sheet.
