Document Type and Number:
Japanese Patent JPS5444242
Kind Code:
A
Abstract:
An electric igniting element as used in automobile cigar lighters, jet engine igniters and like devices, comprising 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, which greatly facilitate the coil winding process, effect a greater uniformity, extend the range of coil stock that can be handled while at the same time resulting in a nesting and interlocking of the convolutions that not only provide a mutual support of the same but also produce a small coil having a high metal density.
