摘要

Apparatus for detecting defects in a web of textile material as it is being drawn through an inspection zone. A header is arranged to project a line of light on the running web and a reflected light image from the web is sensed and analyzed for defects. The header includes a fiber bundle for producing a line of light and an optical element for collimating the light upon the web as it passes through the inspection zone.
