<p>a method of producing steel fibres, preferably for use as concrete additive, and for the supply thereof in the production of steel fibre concrete, characterised in that to form the steel fibres (2) firstly a sheet metal strip (1) is notched either on one side or both sides, whereby steel fibre veins (4) are formed, wihich are initially still connected together by limbs (5), that further for subsequently converting the limbs (5) into thin easily mutually separable separation limbs forming separation furfaces which are fracture-rough and low in burring upo n sepration the steel fibre strip is subjected to a flexing process in which each limb (5) is subjected to multiple bending deformation about its longitudinal axis in such a way that inciplent cracks are produced in the region of the limbs (5) due to fatigue fracture and thus the separation limb is produced.</p> |
