Abstract

Dispositif de revêtement pour appliquer un matériau de revêtement sur une surface en mouvement. Le dispositif comprend un boîtier (16A) formant une chambre (18A) pour recevoir le matériau de revêtement (12A). Le boîtier (16A) comprend en outre une fente de sortie (20A) permettant le passage du matériau de revêtement (12A) provenant de la chambre (18A). Un dispositif de cisaillement (28 A-G) est disposé à l'intérieur de la chambre pour cisailler le matériau de revêtement avant son application sur la surface (14A). Le cisaillement diminue la viscosité du matériau de revêtement et maintient cette viscosité à un niveau réduit avant l'application, de manière à faciliter l'écoulement uniforme du matériau à travers la fente de sortie disposée perpendiculairement par rapport au défilement de la surface.
