  • Precision center guiding of a web coated with light sensitive photographic emulsion
    Patent number: 5679161
    Abstract: An apparatus and method for detecting the edge of a light sensitive photographic emulsion on a support is described. The method and apparatus include a pair of collimated infrared light sources for illuminating each edge of the support at an angle of incidence of greater than 0.degree. to about 45.degree.. Positioned above the edges of the support are a pair of CCD cameras. Light scattered by the support and emulsion is detected by the CCD cameras and the edges of the emulsion and the edges of the support are detectable. Signal means are used to generate a signal corresponding to the position of the emulsion on the support. A conventional guider receives the signal and positions the support accordingly.
