ABSTRACT:
A continuous wire feed arrangement for feeding wire to a stapling apparatus or the like comprises two nozzles respectively located along paths along which wires may be fed to a device for cutting and transmitting cut wire portions to the stapling apparatus. The wire feed is carried out at any time only to one of the nozzles. Each of the wires is withdrawn over a guide roll and a wire feed device from a wire reel. The respective fed wire closes thereby over the guide roll an electric circuit. When this circuit is interrupted due to running out of wire on one of the wire reels, or due to interruption of the feed of the one wire, the transport of the other wire is automatically initiated. The changeover of the wire transport from one to the other wire reel is carried out by electromechanical elements. In this way a continuous uninterrupted wire supply to the cutting and transmitting device is assured.
