Effects of the wire shape in bundles and the wire feeding conditions on shape of formed coils are studied experimentally. Although they are important problems in the cold coiling of springs, they have never been studied because of their complexity. The main results are as follows. 1) The wire shape in bundles and the inclination angle of the reel plane produces the combined load of bending moment and torsional moment on wires during coiling by a deformation trend of the wires, which is related to the changes of shape of formed coils with the interaction between yield-point loads. 2) The effect of feeding conditions on shape of formed coils seems to decrease as feeding wires straighten. 3) Instructions on the selection of the wire shape in bundles, the setting of the reel plane and on the compressire force of feed rollers are given on the basis of the experimental results.
