Nozzle head for applying an insulating means

The invention relates to a nozzle head (5) for emitting a spray jet of a coating agent, in particular an insulation means, whereby a certain volume flow of the application means is applied by the spray jet and the spray jet is substantially flat in a jet plane, while the spray beam in the beam plane in a specific beam width which is dependent on the volume flow of the application means. It is proposed that the nozzle head (5) is designed such that the beam width is independent of distance constant within a large volume flow workspace substantially.
