Abstract (en)
[origin: WO2010060223A1] Using a method for producing a spring (1) from a spring wire (6), turns of a first spring part (10) are produced, wherein said produced turns move in a first direction (B). Thereafter, turns of a second spring part (12) are produced, wherein said produced turns move in a second direction (C) which is different from, in particular opposite of, the first direction. Such a method can be used to produce a spring having a plurality of spring parts in a simple manner.
