The invention relates to a device for coating at least one running flat material web (10) on both sides, comprising a first and a second coating nozzle (2, 3). The first coating nozzle (2) can be advanced towards the first face of the flat material web (10), and the second coating nozzle (3) can be advanced towards the second face of the flat material web (10) in order to coat the respective face of the flat material web (10). At least one of the coating nozzles (2, 3), preferably both of the coating nozzles, can be moved from a working position into a maintenance position (A, W) and back. The device also comprises supply line sections (4, 8) with flow channels (4a,8a) which are formed in the supply line sections, which are connected together in the working position (A) and which ensure a flow in order to supply a hot liquid coating material to each coating nozzle (2, 3). When at least one of said coating nozzles (2, 3) is converted from the working position into the maintenance position (A, W), a first and a second rigid supply line section (4, 8), which allow a flow of the coating material to the coating nozzle (2, 3) in the working position (A), are automatically moved relative to each other such that the flow channels (4a, 8a) formed in the supply line sections are moved relative to each other in order to interrupt the flow of the coating material to the respective coating nozzle (2, 3). |
