Abstract
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.
