Station for the control of an atomized current

摘要

A coating station for coating a thin layer of coating composition on a web which comprises a housing having an inlet connected to a source of pressurized air and provided with a plurality of atomizing means for the coating composition arranged in a row running parallel to the path of the web, and further having mutually diverging upper and lower wall means defining a space with a rectangular cross-section operative to decrease the velocity of the air current loaded with atomized coating composition, and converging upper and lower wall means causing an homogenizing of said loaded air current, and an elongate outlet port causing acceleration of said air current and application thereof onto said web.
