Abstract
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, a conveyance roller pair, and a separation claw. The winding roller rotates and winds the two-ply sheet. The conveyance roller pair conveys the two-ply sheet toward the winding roller. The separation claw is inserted into a gap between the two sheets at a position between the winding roller and the conveyance roller pair. The separation claw is disposed in a space that is bounded by an imaginary plane and includes the winding roller. The imaginary plane passes through a nip of the conveyance roller pair and a winding start position at which the two-ply sheet starts to be wound around the winding roller.
