ABSTRACT:
Disclosed herein is a method and apparatus for producing a barrel-shaped coil spring, by forming a coil spring having a first pig tail at one end, with a second pig tail at the other end. The method comprises providing a winding jig having a spiral stepped portion suited for forming a desired second pit tail; inserting the winding jig into the other end of the coil spring; and providing a rotary spindle for modifying the other end of the coil spring axially and radially relative to the winding jig, thereby winding the other end of the coil spring around the winding jig to form the desired second pig tail. Apparatus for performing the method is disclosed which comprises a winding jig and a cooperative rotary spindle to provide the second pig tail on the coil spring.
