The pipe is connected via through-flow openings to a feed duct merging into a metering gap forming a free-jet nozzle. The pipe may alternatively be coupled to an application chamber. The through-flow openings are arranged in an upper portion of the distribution pipe and at least one discharge opening for fluid or pasty medium is provided at any one or more other portions of the distribution pipe.
