L'invention concerne une unité d'application (101;101') comprenant un appareil d'alimentation en poudre (700; 700') pour fournir un matériau pulvérulent (004; 004'), l'unité d'application (101;101') comprenant un premier rouleau (102; 102') et un second rouleau (103; 103') qui forme un espace de rouleau (104 ; 104') avec le premier rouleau (102; 102'), un espace de remplissage et/ou de tampon (126) étant formé et/ou prévu dans la région du tympan (108) formée au-dessus de l'espace (104 ; 104') entre les surfaces latérales des premier et second rouleaux (102 ; 102' ; 103 ; 103'), espace dans lequel un matériau pulvérulent (004 ; 004') peut être fourni par le biais d'un appareil de distribution (701) compris dans l'appareil d'alimentation en poudre (700 ; 700'), l'appareil de distribution (701) ayant un récipient (751) qui a une base (753) et qui peut être amené à vibrer par un entraînement vibratoire (707), une ouverture (752) disposée dans la base (753) du récipient (751) étant jointe sur le côté de sortie par un canal d'alimentation (756) par l'intermédiaire duquel le matériau pulvérulent (004; 004') peut être évacué du récipient (751) dans l'espace de remplissage et/ou de tampon sous-jacent (126). Sur le côté de sortie, le canal d'alimentation (756) pénètre avec une sortie dans l'espace de remplissage et/ou de tampon (126) formé au-dessus de l'espace de rouleau (104 ; 104') dans le tympan (108) entre les surfaces latérales du premier rouleau (102 ; 102') et du second rouleau (103 ; 103'). L'invention concerne également un appareil de revêtement (100 ; 100 *) pour revêtir un substrat de support (006) d'un film sec (003 ; 003').
