A method includes steps of: carrying an air-permeable web while holding the first surface of the web on a carrying surface dispensing powder particles onto the second surface of the web drawing the first air from a plurality of suction holes in the carrying surface through the web, thereby holding the powder particles in a predetermined pattern on the second surface of the web and giving at least a part of the first air flow components flowing in directions along the second surface of the web by means of an airflow deflector opposing the second surface of the web, thereby moving powder particles on non-suction areas between the suction holes on the web, thus arranging the powder particles in a predetermined pattern on the web.
