Abstract: The invention concerns a steel fibre for reinforcing castable, hardening materials, in particular concrete, the fibre extending substantially along a longitudinal axis and having longitudinal edges which deviate from the rectilinear shape. The invention is characterized in that the steel fibre is formed by a narrow sheet metal strip of uniform thickness (sheet thickness D), the longitudinal edges of this strip, viewed as cutting edges in the sheet plane, each having congruent wave-like shapes shifted parallel to one another and substantially composed of a series of polygons, the width of the parallel shift (b) being such that a continuous rectangular material strip (width d) is produced in the sheet plane between the wave-like longitudinal edges over the entire fibre length (I). The invention further concerns a method of producing this steel fibre.

Abstract: A process is disclosed for manufacturing steel fibres with a length/diameter ratio lower than 50 for fibre concrete. A steel starting stock (3) is machined by means of a rotary milling cutter (1) that is moved relatively to the longitudinal axis of the steel input stock. In order to produce fibres with different adjustable lengths and cross-sections, a steel starting stock (3) having a cross-section that is symmetrical about its longitudinal axis is used as steel starting stock (3), the steel starting stock (3) is made to rotate around its longitudinal axis during the whole machining process and the machining process is carried out without liquid coolant or lubricant.
