Abstract

La présente invention concerne un système d'application de revêtement fluide sur un substrat par formation d'une ligne mouillante fluide grâce à l'introduction d'un courant de fluide sur une première face du substrat le long d'une zone de contact du fluide-bande se présentant latéralement. En l'occurrence, on crée une force électrique s'appliquant sur le fluide à partir d'un champ électrique effectif depuis un endroit de la seconde face du substrat, et jusqu'à un endroit sensiblement au niveau de la zone de contact du fluide, mais en aval de celle-ci. Le champ électrique peut être produit de façon très efficace par rapport au fluide de revêtement grâce à une électrode finement définie sur la seconde face du substrat. Des champs ultrasoniques se combinant à des champs électrostatiques améliorent encore plus les conditions de traitement du revêtement et l'uniformité du revêtement.
