摘要：it is a doppelspirale with two teilspiralen (10, 20) of the same windungssinndescribed. the teilspiralen (10; 20) oval cross-section with nearly straight upper and lowerwindungsschenkeln (12, 13, 22, 23), and with opposite windungsb\ögen (11; 21). themutually facing windungsb\ögen (11; 21) of the two teilspiralen (10, 20) umgreifeneach other.the upper windungsschenkel (12; 22) of the teilspiralen (10; 20) are from adifferent angle to the longitudinal axis of the teilspiralen (10, 20) as the lowerwindungsschenkel (13, 23) of the respective teilspirale (10, 20) and the upper
windungsschenkel (12) of a teilspirale (10) are under the same angle to the longitudinalaxis of the lower windungsschenkel (23) of the other teilspirale (20), and vice versa. forthe manufacture of such a doppelspirale the two spiraldr\ähte parallel to aremarkable rejuvenation thorn wrapped.the doppelspirale can be used in themanufacture of a spiralgliederbandes,with the teilspiralen adjacent doppelspiralenopposite windungssinn and windungsb\ögen a teilspirale one doppelspirale withwindungsb\ögen a teilspirale the other doppelspirale rei\ßverschlu\ßartigare brought in operation and by the educated a steckdraht channel is introduced.
