Abstract
A method and apparatus for producing coil springs formed of wire and with elets formed at the ends thereof are disclosed. The apparatus includes a machine for winding spring bodies detachably affixed to apparatus for transferring them from the winding machine to first and second successive eyelet forming stations wherein, at the first forming station, an eyelet is formed at one end of the spring body and, at the second forming station, an eyelet is formed at the other end of the spring body. The spring bodies are divided into transport groups and supply groups arranged side-by-side on upwardly and downwardly inclined ramps, respectively, with their longitudinal axes parallel and at right angles to the transfer direction. Delivery devices are provided between the downwardly inclined, gravity feed supply ramps and the upwardly inclined transport ramps for the stepwise delivery of spring bodies to the eyelet forming stations.
