Abstract: The invention relates to a radial turbine. The radial turbine comprises: —a turbine housing having a radial gas inflow channel; —a nozzle ring, which is disposed in the radial gas inflow channel; and —an annular cleaning device for cleaning the nozzle ring. The annular cleaning device is connected to a cleaning-agent feed by means of an axially insertion-connectable supply line such that, after or during the demounting of the nozzle ring, the annular cleaning device can be removed from the turbine housing in the axial direction. The invention also relates to a method for mounting a cleaning device for cleaning a nozzle ring of a radial turbine and to a method for demounting the cleaning device.

Abstract: Methods and apparatuses for coating a flexible substrate are provided. The flexible substrate is guided over a process roller. The flexible substrate has a first protective film, which is removed from the flexible substrate before the flexible substrate reaches a coating zone of a coating device located opposite the process roller. The first protective film is removed from the flexible substrate after the flexible substrate has formed a mechanical contact with the surface of the process roller. A second protective film is applied to the coated side of the flexible substrate after the flexible substrate has left the coating zone of the coating device and before the mechanical contact between the process roller and the flexible substrate is ended.
