Abstract
Dans le procédé de l'invention, on déplace une nappe 3 sous un alimenteur 1 à plan incliné 5 à partir duquel s'écoule une composition d'enduction 8, 9 sous la forme d'un rideau 10 qui tombe sur la nappe. On crée entre le rideau et un élément 12 ayant un profil particulier, un écoulement d'air laminaire F afin de rendre le rideau insensible aux courants d'air intempestifs et d'obtenir un revêtement 15 contrôlé de meilleure qualité. Application : fabrication des pellicules photographiques.
