Wilmington, Del., assignors to E. I. du Pont de Nemours and Company, Wilmington, Del., a corporation of Delaware Filed Aug. 8, 1968. Published Apr. 29, 1969 Int. Cl. G01n 21/30; H01j 39/12, 3/14 US. Cl. 250-219 3 Sheets Drawing. 16 Pages Specification An apparatus for detecting package formation defects on the end surface of a rotating cylindrical yarn package wherein at least two parallel strips of light are projected onto the end surface. The illuminated portions of the end surface are viewed and the illumination therefrom is directed to photosensitive means which detects variations in the intensity of the illumination and emits electrical signals equivalent thereto. Electronic components are provided to amplify and discriminate signals received from the photodetectors in order to detect and record defects exceeding predetermined levels. Means are also provided to segregate inspected packages having unacceptable package end formations. A duplicate apparatus arrangement is provided for simultaneously inspecting both end surfaces of the package.
