1. Apparatus for feeding wire to wire-processing machines, the apparatus comprising:
- a rotatable pay-off reel holding a wire coil from which the wire is drawna wire feeder upstream of the wire-processing machine, the wire fed to the wire feeder from the pay-off reel;
at least one wire-deflecting device positioned intermediate the pay-off reel and the wire feeder for guiding the wire;
a wire-storage device provided in the form of a spring wheel upstream of the wire feeder, said spring wheel defining a circumferential guide path with the wire extending therearound and positioned at a diameter, the diameter of which can be altered between a smaller value corresponding to an inner radial position of the guide path and a larger value corresponding to an outer radial position of the guide path, and being rotatable about a spindle lying perpendicular to a direction of advance of the wire and comprising two circular side parts which act as lateral limiting plates for the wire and being spaced apart from each other by a distance,said side parts defining recesses in radial alignment and uniformly arranged over the circumference of the spring wheel, said recesses receiving a plurality of radially arranged compression springs that define said guide path,said distance between the side parts being smaller than a diameter of each of the compression springs, the diameter of each of the compression springs being defined in a direction parallel to the spindle of the spring wheel, and wherein each compression spring is held in two recesses formed radially in the two side parts.

Abstract
An apparatus for feeding wire to wire-processing machines, in which the wire is drawn off from a pay-off reel holding a wire coil and rotatable about a spindle and fed to a wire feeder upstream of the wire-processing machine, wherein at least one wire-deflecting device, via which the wire drawn off from the pay-off reel is guided and released towards the wire feeder, is connected downstream of the pay-off reel in the wire draw-off direction, and wherein a wire-storage device is provided upstream of the wire feeder, this apparatus presents a guide path, forming a closed circuit, on which the wire runs and the diameter of which can be altered between a smaller value corresponding to an inner radial position of the guide path and a larger value corresponding to an outer radial position of the guide path, wherein the guide path is spring-pretensioned towards the outer radial position.
