The invention relates to a device for the application of a liquid medium onto at least one side of a moving material web, specifically a cardboard web, including at least one roll and at least one feed device for the coating medium, whereby during operation of the device a liquid sump forms between the roll and the web. Nozzle lips of a nozzle body of the feed device are configured so that the desired dimension of the open surface of the liquid sump and the depth of immersion of the nozzle lips into the liquid sump, and thereby the level of the liquid sump are adjustable. The nozzle lips are surrounded up to 80% of their total length by the liquid sump.
