Claim:
A spring forming apparatus, comprising: means for forcibly feeding a linear material having at least a pair of feeding rollers for feeding said material to a spring forming stage via a quill; revolving means for revolving said feeding rollers about the axis of said linear material to twist the material fed out of the leading end of said quill, thereby changing the circumferential position, or angular position, of said material relative to said spring forming stage; a multiplicity of spring forming tools arranged radially on said spring forming stage, each of which is movable to and from said linear material in a direction substantially perpendicular to the axis of the linear material, said spring forming tools adapted to be advanced to abut against said material fed to said spring forming stage so as to bend, curve, or turn said material, thereby forming a spring, and a quill moving assembly for controllably moving and affixing said quill to a selected point in the axial direction of said linear material; wherein motions of said feeding means, and revolving means, are controllable.
