Abstract (en)
[origin: US4599881A] In a method and an arrangement for winding and forming helixes of elastic synthetic plastic and metal wire the wire is supplied from a wire supply device, windings are then wound from the wire so as to form straight winding legs connected by head curves, the windings are then separated to provide distances therebetween, the separated windings are widened in correspondence with the distances between them produced during the separation and the finished helixes are supplied to a helix supply device.
