ABSTRACT:
A spring manufacturing apparatus for reducing the time from the beginning to the completion of the manufacturing of a spring having a flat end surface and for manufacturing a large amount of springs at a high-speed. Feed rollers 3a and 3b supply wire material 1 to point tools 4a and 4b. When a single spring is formed, laser output portion 7 is moved in an X direction by the spring pitch length and laser irradiation to the wire material 1 is started. At the same time, feed rollers 3a and 3b feed the wire material for one coil of spring to be manufactured.
