La présente invention empêche l'apparition d'un revêtement inégal provoqué par le rabat d'un tissu ou des défauts tels que la courbure ou le mou dans ledit tissu tout en empêchant l'apparition d'un revêtement strié et inégal et qui permet un revêtement uniforme d'un film mince. La présente invention se rapporte à un dispositif qui recouvre la surface d'un tissu mobile (12) ayant un liquide de revêtement prescrit évacué d'un orifice de refoulement en forme de fente (15) dans un moyen d'alimentation en liquide de revêtement (14) qui s'étend dans le sens de la largeur du tissu. En plus du positionnement de l'orifice de refoulement en forme de fente (15) sur le trajet en plein vol du tissu (12), un moyen d'entraînement (20) qui entraîne le tissu (12) avec une force de compression uniforme dans le sens de la largeur du tissu qui est orienté vers l'orifice de refoulement en forme de fente (15), est disposé à une position qui est orientée vers l'orifice de refoulement en forme de fente (15), le tissu (12) étant positionné entre ces derniers.
