ABSTRACT An electric igniting element as used in automobile cigar lighters, jet engine ignitors and like devices, com- prising a spirally wound tight coil made of metal heater ribbon which is transversely formed to have a cross-sectional configuration roughly similar to a wide-spread letter "V" but with a flattened bottom portion and two beaded edge surfaces along one side. The advantage of the present con- struction over prior devices is that there is greatly facilitated the coil winding process, enabling a greater uni- formity to be had and extending the range of coil stock that can be handled, while at the same time resulting in a nest- ing and interlocking of the convolutions that not only pro- vide a mutual support of the same but also produce a small coil having a high metal density.
