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.
