Abstract
Using a method for producing a spring from a spring wire, turns of a first spring part are produced, wherein said produced turns move in a first direction. Thereafter, turns of a second spring part are produced, wherein said produced turns move in a second direction 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.
