The invention concerns a coating device for coating a travelling web travelling past the coating device. A chamber for coating composition has an exit mouth, and pressurized coating composition exits the mouth into an application space between the mouth and the web. A doctor blade for the web is downstream of the application space. A damming strip with an edge spaced from the web is upstream of the application space. The damming strip defines an exit slot for excess coating composition in the application space. A flow body in the application space includes feed channels leading from the mouth toward the web and includes passage openings extending generally transversely of the feed channels for conducting the rotary flow of coating composition through the application space. The flow body has obstacles above the exit ends of the feed channels which make the flow therearound more uniform. |
