Abstract

L'invention est relative à un procédé pour le réglage de la quantité de substance active appliquée sur des bandes de papier continues dans lequel on fait passer la bande de papier dans un dispositif de revêtement muni d'une ouverture en forme de fente, caractérisé en ce que le récipient est alimenté par au moins deux courants partiels qui sont mélangés l'un avec l'autre avant leur passage à travers l'ouverture en fente, le premier de ces courants consistant en un liquide ayant une teneur prédéterminée en substance active et le second courant consistant en un solvant pur ou un agent de dispersion, les courants partiels précités étant chacun obtenus au moyen de dispositifs de dosage ou de mesure du débit réglables indépendamment l'un de l'autre, de sorte que la bande est recouverte entièrement par le liquide de traitement formé par les courants partiels après le mélange.
