Abstract (en)

[origin: WO2011018064A1] The invention relates to a method for separating wires or strips from wire strips or strip wires, starting from a wire strip consisting of a plurality of wires (1) which are arranged parallel to each other. In that in order to form the wires (1) of the wire strip, initially a metal strip is notched on either one or both sides. The wires (1) still connected to webs after notching are subjected to a tumbling process in order to subsequently reshape the webs into thin, easy to separate separating webs which form separating surfaces that are smooth and low in burrs. As a result, each web is subjected to multiple bending deformation steps about the longitudinal axis such that incipient cracks forming the separating webs are formed in the region of the webs due to fatigue fracture. The wire strip is wound in the form of a disk or coil, layer upon layer, to form a separating strip pack (2). In order to further process individual or multiple wires (1) which are still connected together, said wires are separated on the front side of the rotatably mounted separating strip pack (2) by means of one or more roller separating blades (3) guided on a plane perpendicular to the axis of the separating strip pack (2) and fed to a post-processing installation.
