ABSTRACT:
A method of manufacturing a coil spring wherein, an amount of sway of a connecting body connected to a swaying body to be swayed by a cam or a crank driven by a driving shaft rotating at a constant speed in order to drive at least one or more means among those for changing a pitch of active coils, forming the end portion, changing the shape of cross-section of the active coils and cutting wire material is converted into a pulse signal and is then measured on the occasion of manufacturing a coil spring and a DC servo motor which drives and rotates a core bar or pressurized co-roller for supplying a wire material to the coil forming portion is driven by such pulse signal in order to form a total coils of a coil spring.
