Title
(EN) AN IN-LINE PROCESS FOR MONITORING BINDER DOSAGE AND DISTRIBUTION ON A SURFACE AND APPARATUS USEFUL THEREFOR
(FR) PROCESSUS EN LIGNE DE CONTROLE DU DOSAGE ET DE LA REPARTITION DE LIANTS SUR UNE SURFACE ET APPAREIL UTILE POUR CE FAIRE
Abstract
(EN)
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 c) into an electrical signal; and means (10) for correlating images received by video camera d) to binder dosage and distribution on the substrate contacted by the ultraviolet waves emitted by source a).
(FR)
Un procédé et un appareil de détermination du dosage et de la distribution de liants sur un substrat comprennent: a) une source (2) de lumière ultraviolette à ondes longues positionnée de manière que des ondes ultraviolettes émises à partir de celle-ci (1) viennent au contact d'un substrat (3) auquel un liant a été appliqué, b) un filtre (5) lequel bloque les ondes ultraviolettes émises par la source a) et réfléchies par le substrat mais permet le passage des ondes (4) de lumière visible émise par la fluorescence du liant, c) une lentille (6) destinée à imager la lumière visible sur un plan focal, d) une caméra vidéo (7) positionnée au niveau du plan focal de la lentille c) laquelle convertit les ondes de lumière visible ayant traversé le filtre b) et la lentille c) en un signal électrique, et e) un moyen (10) destiné à corréler les images reçues par la caméra vidéo d) avec le dosage et la répartition du liant sur le substrat ayant été en contact avec les ondes ultraviolettes émises par la source a).
