Abstract

"Procedure for the optical control of float glass", by the method of shadows with reflected light, characterized in that the glass band is illuminated in all its width, by means of a light beam directed transversely under an angle of incidence higher than 60 degrees, and because the image is observed in a plane, normal to the plane of incidence, whose distance and inclination on the vertical, make this image, noticeably narrower than the band itself.
