Abstract: An apparatus for coating web-shaped materials with a coating medium includes a rotating transfer roll that has depressions on its circumferential surface for transferring the coating medium, a coating chamber, and a nozzle carrier with several bored holes before the coating chamber in a motion direction of the transfer roll. Coating medium streams out of these bored holes in a free stream. The apparatus aims to achieve a uniform and reproducible coating of the web for various different application weights.

Abstract: The invention relates to an apparatus (1) for the coating of web-shaped materials with a coating medium. The apparatus (1) comprises a rotating transfer roll (3), which has depressions on its circumferential surface (5) for the transfer of the coating medium, a coating chamber (12), and a nozzle carrier (14) with several bored holes (15, 15?) before the coating chamber (12) in a motion direction of the transfer roll (3). Coating medium streams out of these bored holes (15, 15?) in a free stream. This apparatus (1) ensures a uniform and reproducible coating of the web for various different application weights.
