Apparatus for inspecting irregular coupling elements from continuously running slide fastener chains (30) is essentially comprised of a light source (12) including a light emitter and a light receptor, an optical fiber (13) extending from the light source (12) and having a leading end arranged to face a row of coupling elements (32) along their rounded corners, and a comparator (25) connected to the light source. The light emitter cooperates with the optical fiber (13) in emitting light rays onto the coupling elements (32), and the light receptor receives via the optical fiber light rays reflected from the rounded corners and converts the reflected rays to electrical signals. The comparator (23) successively compares the signals to the reference standard to detect irregular coupling elements (33). |
