Abstract
The method serves for the production of a wire strip (1) comprising a plurality of wires (2) arranged parallel to each other. For this purpose a metal strip is first pre-notched either on one side or both sides for the formation of the wires (2), whereby wires (2) are generated which are still connected to webs (3). To transform the webs (3) subsequently into thin, easy to separate and, when separated, smooth and burr-free separation webs forming separation areas, the wire strip (1) is subjected to a milling process during which each web (3) is subjected to a multiple bending strain along the longitudinal axis thereof in such a way that incipient cracks form, due to fatigue fracture, in the area of the webs (3), and thereby the separation web is created.

A method of making a strip formed by a plurality of parallel wires from a sheet-metal strip grooved on one or both sides to form wires interconnected by webs the method comprising the step of converting the webs into thin and easily separated webs that when separated form smooth and burr-free edge faces by subjecting the strip to a bending process during which each web is subjected to multiple bends along its longitudinal axis in such a way that incipient cracks form due to fatigue fracture at the webs, and thereby a separation web is created.
