摘要： A method for producing steel fibers, preferably for use as a concrete additive, and for the addition thereof during the production of steel fiber concrete, characterized in that in order to produce the steel fibers (2) first a metal strip (1) is notched either on one side or on both sides so as to form steel fiber veins (4), which initially are still connected to each other by webs (5), and that furthermore the steel fiber strip is subjected to a tumbling process in order to subsequently reshape the webs (5) into thin, easy-to-separate separating webs which form separating surfaces that are smooth and low in burrs during severing, wherein each web (5) is subjected to multiple bending deformation steps about the longitudinal axis such that incipient cracks are formed in the region of the webs due to fatigue fracture, thereby producing a separating web.

摘要： The metal fiber has fiber outer surfaces (1) oriented substantially at right angles to each other and can also be provided with bent ends in the shape of a clip. The metal fiber is used to stabilize, strengthen, or fasten materials such as concrete, wood, and the like. The fiber edges (2) formed by the fiber outer surfaces (1) of the metal fiber and extending in the longitudinal direction of the fiber are designed as edge surfaces (4) oriented at an angle to the fiber outer surfaces (1) in the manner of a chamfer. Said edge surfaces (4) have projections, which form anchoring heads (3) that are anchored in the materials to be stabilized, strengthened, or fastened.
