Claim Text:
1. A method of making a strip formed by a plurality of parallel wires wherein a sheet-metal strip is first grooved on one or both sides to form wires interconnected by webs, characterized in that, for the subsequent conversion of the webs into thin and easily separated webs that when separated form smooth and burr-free edge faces, the strip is subjected to a bending process during which each web is subjected to multiple bends along the longitudinal axis of the strip, wherein the strip is alternated between an inclined position and a declined position with respect to the lateral width of the strip as the strip is subjected to the multiple bends and in such a way that incipient cracks form due to fatigue fracture at the webs, and thereby a separation web is created.
