Abstract

L'invention concerne un appareil d'analyse de défauts sur une feuille continue mobile. L'appareil comprend une source de rayonnement 16 ou 17, un séparateur de faisceau 18 renvoyant la lumière de la source 16 à un miroir analyseur 20, un masque 24 formé par une forme allongé 25 qui laisse passer le rayonnement, à travers un filtre 26, jusqu'à un détecteur photoélectrique 27. La tâche mobile 28 balaye transversalement la feuille mobile 13. L'invention s'applique aux installations fabricant ou utilisant des bandes continues mobiles de papier.
