Zusammenfassung:The invention is based on a method of producing bent spring elements from a spring steel strip, wherein a feed unit delivers the spring steel strip from a supply roll to a bending unit having at least three bending rollers and a reverse bending roller, of which at least one bending roller and the reverse bending roller can be adjusted transversely to the spring steel strip by bending motors, and wherein a cutting-off unit adjoins the bending unit, said cutting-off unit cutting off the spring steel strip into individual spring elements by means of cutting-off tools. It is proposed that the cutting-off tools be movable in the longitudinal direction of the spring steel strip in a numerically controlled manner and that they be synchronized with the feed movement of the spring steel strip during the cutting-off operation.
