... through restricting guides against a coiling point and around a fixed arbor into a coil. At the end of the coiling cycle, the feed rolls stop, and a cutoff mechanism actuates a knife, which severs the completed spring against the arbor. A flying knife separates the completed spring from the wire strand...
