Abstract

L’invention concerne un procédé de production de fibres d’acier à utiliser, de préférence, comme additif pour le béton, ainsi que leur acheminement lors de la production de béton renforcé de fibres métalliques, caractérisé en ce qu’une tôle en bande (1) est tout d’abord entaillée d’un côté ou des deux côtés pour la formation des fibres métalliques (2), ce qui donne des brins de fils métalliques (4) qui, dans un premier temps, sont encore reliés ensemble par des segments (5), en ce que pour transformer ensuite les segments (5) en segments de séparation minces, facilement séparables les uns des autres et formant lors de la séparation des surfaces de séparation lisses et sans arête, la bande de fibres métalliques est soumise à un processus de foulage au cours duquel chaque segment (5) est soumis à une déformation par flexion multiple autour de son axe longitudinal de manière à former des amorces de fissures de fatigue dans la région des segments et à obtenir ainsi le segment de séparation.The invention relates to a method for producing steel fibers, preferably used as an additive for concrete, as well as their routing during the production of concrete reinforced with metal fibers, characterized in that a sheet metal strip ( 1) is first notched on one side or on both sides for the formation of the metal fibers (2), which results in wire strands (4) which, at first, are still connected together by means of segments (5), in that to then convert the segments (5) into thin separating segments, easily separable from each other and forming at the separation of the smooth and boneless separation surfaces, the metal fiber web is subjected a crimping process in which each segment (5) is subjected to multiple flexural deformation about its longitudinal axis so as to form fatigue crack primers in the region of the segments; t thus to obtain the separation segment.
