<p>An apparatus for producing wire springs comprising: a first working station including a wire support and cutting means adapted to cut the wire against the support, a second working station including a rod about which the wire is wound, and clamping means for securing the wire against an end portion of the rod, these means being constituted by two controllable vices arranged in diametrically opposed positions with respect to the axis of the rod. In the portion thereof facing the rod, these vices are so shaped as to show a respective planar or slightly concave surface towards the rod. Wire cutting occurs according to a radial sectioning plane with respect to the support and is arranged so that the spring is cut in a manner that the wire remaining on said support is wound thereabout by an angle greater than 180°.</p> |
