<p>Apparatus for detecting flaws in a continuously moving ribbon of float-formed glass, comprising optical elements constructed and arranged to direct scanning beams of light through the glass ribbon, and which, in combination with associated discriminating means, afford a system which detects discrepancies in the transmission of light in the region of a flaw contained in the glass. In addition to the optical elements, the apparatus comprises a flaw marking unit and a control unit. Information as to the exact nature (e.g. wave, ream, bubble, and viscous lump) and location of marked flaws in the inspected glass may be stored in a computer, in the order of severity of the flaw.</p> |
