A cyclically operable spring coiling machine includes a pair of feed rolls for intermittently advancing wire longitudinally to a coiling station. A coiling arbor and a coiling tool at the station cooperatively form leading end portions of the wire to a coil spring configuration and a cutoff tool severs the coiled leading end portions of the wire to provide individual coil springs. A diameter slide carries the coiling tool and is movable approximately along the line of wire feed movement but on a side of the coiling arbor opposite the feed rolls. A second coil starter slide mounted on the diameter slide is movable along a line of movement in a lateral direction approximately at right angles to the diameter slide movement. A coil starter motor is mounted on the machine frame and a power transmitting means including a universal joint means connects the motor with the coil starter slide to move the latter between operative wire coiling and coil starting positions. The latter position is spaced laterally from the coiling arbor to allow a short leading end portion of wire to be coiled to project beyond the arbor and be thereafter engaged by the coiling tool and bent about the arbor for a coil starting operation on lateral movement of the coil starter slide and coiling tool from its said starting position to its operative coiling position. An adjustment slide movable along a line of movement at right angles to the diameter slide and the coil starter slide is included as are back lash springs within a dove tail slide arrangement on the diameter slide.
