Electrically conducting pole- bridging elements are formed on igniters having a planar surface formed by contiguous end surfaces of first and second pole bodies 2, 3 of the igniter and an electrically insulating body 4 therebetween, by (1) arranging a plurality of said igniters so so that their planar surfaces lie in a common plane; (2) positioning a mask 11 adjacent said planar surface, said mask having openings therethrough of configuration corresponding to the pole-bridging elements; and (3) depositing electrically conductive material onto said planar surfaces through said mask openings. Apparatus for carrying out this method includes a recessed support 8 for mounting the igniters and a force plate 12 comprising individual springs 12a to press each igniter against the under surface of the mask. <IMAGE> |
