An in-line process for monitoring binder dosage and distribution on a surface and apparatus useful therefor

A method and apparatus for determining binder dosage and distribution on a substrate comprising: (a) A source (2) of long wave ultraviolet light positioned so that ultraviolet waves emitted therefrom (1) will come into contact with a substrate (3) to which binder has been applied; (b) A filter (5) w...

Summary:A method and apparatus for determining binder dosage and distribution on a substrate comprising: (a) A source (2) of long wave ultraviolet light positioned so that ultraviolet waves emitted therefrom (1) will come into contact with a substrate (3) to which binder has been applied; (b) A filter (5) which blocks ultraviolet waves emitted from source (a) and reflected by the substrate but allows visible light waves (4) emitted by fluorescence of the binder to pass; (c) A lens (6) for imaging visible light onto a focal plane; (d) A video camera (7) positioned at the focal plane of lens (c) which converts the visible light waves that have passed through filter (b) and lens into an electrical signal; and (e) Means (10) for correlating images received by video camera to binder dosage and distribution on the substrate contacted by the ultraviolet waves emitted by source.
