A die coating method and apparatus includes a die (40) having an upstream bar (64) with an upstream lip (60) and a downstream bar (66) with a downstream lip (62). The upstream lip (60) is formed as a land (68) and the downstream lip (62) is formed as a sharp edge (70). The shape of the land conforms to the shape of the surface being coated. Changing at least one of the slot height H, the overbite O and the convergence C can improve coating performance. A replaceable, flexible strip (350) can be used above the coating slot to facilitate replacement of a damaged overbite edge. A low surface energy coating can be applied to the downstream bar and land surfaces.

L'invention concerne un procédé et un appareil d'enduction à filière. Ledit appareil comporte une filière (40) présentant une barre d'amont (64) dotée d'une lèvre d'amont (60), et une barre d'aval (66) dotée d'une lèvre d'aval (62). La lèvre d'aval (60) présente la forme d'un listel (68), et la lèvre d'aval (62) celle d'une pointe (70). Le listel suit les contours de la surface à enduire. La modification d'au moins une des valeurs suivantes, la hauteur H de la fente, le positionnement O du bord de contact ou la convergence C, peut améliorer l'efficacité de l'enduction. Une bande souple amovible (350) peut être utilisée au-dessus de la fente d'enduction pour faciliter le remplacement d'un bord de contact. Un revêtement à faible tension de surface peut être appliqué sur les surfaces de la barre d'aval et du listel.
