Zusammenfassung:	In order to create a method for the production of helical springs curved in the unloaded condition from rods heated to coiling temperature, which method makes it possible to produce helical springs with a curved centre line in a single operation, the helical spring is coiled directly on a coiling mandrel curved to match the curvature of the spring centre line.
