Abstract (en)

An abnormality detection method is executed in a fiber processing system (100) in which a pre-process machine (130) executes a pre-process to produce a first fiber bundle and then a post-process machine (150) processes the first fiber bundle to produces a second fiber bundle thinner than the first fiber bundle. The abnormality detection method includes an acquiring step of acquiring pre-process information relating to the pre-process, a thickness detecting step of detecting thickness information relating to a thickness of the second fiber bundle, and an abnormality detecting step of detecting, based on the pre-process information and the thickness information, a non-periodic abnormality occurring in the second fiber bundle.
