ABSTRACT:
A leaf spring shaping machine including upper and lower spring forming elements one of which is constituted by a plurality of closely spaced abutment members, and a mechanism for adjusting and constantly monitoring the positions of said abutment members individually in order to adjust and maintain the effective shape of the one spring forming element. The other of the spring forming elements may be constituted by a pair of arms pivotally connected together and extending outwards from a vertically movable seat clamp which together with a fixed block forms a workpiece clamping arrangement.
