1. A method of producing a cartridge for use in an electrostatic spraying device comprising:

  • forming from a sheet of resiliently deformable non-fibrous, non-felted, hydrophobic material having open porosity a wicking element with a profiled spraying edge;

    furling said element about an axis of elongation thereof to facilitate insertion through an opening in the cartridge during assembly; and

    assembling said element to a container for liquid suitable for electrostatic spraying by inserting said element through an opening in the container so that said spraying edge projects from the container and a portion of the element extends into the interior of the container to provide a capillary feed path for liquid from the container to the profiled spraying edge.
