Abstract: A coiling machine includes feed rollers for moving a wire, a wire guide, a first forming roller, a second forming roller, a pitch tool, a cutting mechanism, and a support mechanism for supporting the wire. The cutting mechanism includes a cutting rotor. The wire coming out of the wire guide is formed into a helical shape by the first forming roller, the second forming roller and the pitch tool. After one coil spring of a predetermined length is formed, the wire is cut by moving the cutting rotor in the radial direction of the wire. The cutting rotor cuts the wire supported by the support mechanism in the radial direction of the wire between the second forming roller and the pitch tool.
