Abstract
A sheet separation device configured to separate a two-ply sheet, in which two sheets are bonded together at a portion, includes a rotator, a nipping member disposed opposite the rotator and configured to nip the two-ply sheet with the rotator, a conveyor configured to convey the two-ply sheet between the rotator and the nipping member, and a winding member disposed adjacent to the rotator. The conveyor 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. The winding member winds the two-ply sheet around the rotator, to create a difference in winding circumferential length between the two sheets and separate the two sheets. The sheet separation device further includes control circuitry configured to adjust a winding amount of the two-ply sheet around the rotator.
