Abstract: In an apparatus for manufacturing springs, a frame body has guide rails on which a pair of movable bodies are mounted to be movable. Each of the movable bodies has rotatable holding rollers between which a wire which is to be processed is held, and each body also has a shaping roller for bending the end of the wire in a coil. Arranged between the shaping roller and the holding rollers are a guide member for defining the supply passage for the wire, and a pitch rod for determining the pitch of the coil formed. When the holding rollers are rotated, while holding the wire, the movable bodies are moved toward each other by the pulling force exerted to the wire, and the wire is supplied from between the paired holding rollers to the shaping roller through the guide member. The pitch rod is reciprocated as the movable bodies run, and as one turn of the wire coil strikes against the pitch rod, making it possible to form spiral springs at both ends of the wire.
