摘要：The invention concerns a steel fibre for reinforcing castable, hardeningmaterials, in particular concrete, the fibre extending substantially along a longitudinalaxis and having longitudinal edges which deviate from the rectilinear shape. The inventionis characterized in that the steel fibre is formed by a narrow sheet metal strip of uniformthickness (sheet thickness D), the longitudinal edges of this strip, viewed as cutting edgesin the sheet plane, each having congruent wave-like shapes shifted parallel to oneanother and substantially composed of a series of polygons, the width of the parallelshift (b) being such that a continuous rectangular material strip (width d) is produced inthe 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.
