ABSTRACT:
An apparatus for making a bubble spring assembly includes a base member having a side surface and a head assembly. A track way extends along one side surface of the base toward the head assembly. The track way is employed for guiding a respective spring blank into the head assembly. A push block is provided for moving the spring blank along the track way and into the head assembly. A shaping mechanism is provided within the head assembly for receiving the respective spring blank from the track way and for shaping the spring into a predetermined form having a predictable stress strain history along the length of the shaped spring blank. A retaining gate is located proximate the shaping mechanism for positioning a respective cavity block adjacent the shaping mechanism. A transfer rod is provided within the head assembly for moving a shaped spring blank from the shaping mechanism into the cavity block in the absence of further deformation to the shaped spring blank.
