This‘ invention relates to a novel ?lter mass
formed of metallic. wire and to a novel‘ method
and apparatus for producing it under controlla
ble conditions so that the density may vary in a
predetermined manner throughout the mass.
Thus in a ?lter in which a gas or liquid is drawn
longitudinally through a cylindrical or conical
mass the density may be made less at the en
trance end, so that the larger particles may be
removed'without plugging, and the density in
