  • Patent number: 11375073
    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 separator, an abnormality detection device, and circuitry. The separator is configured to move to be inserted into a gap formed between the two sheets of the two-ply sheet. The abnormality detection device is configured to detect an abnormal state in which the gap larger than a predetermined size is not formed between the two sheets before the separator is inserted into the gap. The circuitry is configured to control movement of the separator based on a result detected by the abnormality detection device.
