ABSTRACT:
Steel fibers which commonly are comprised of a straight center section and S-shaped end sections are commonly produced in two manufacturing steps: In a first manufacturing step straight sheet steel strips are cut from sheet steel and the resulting steel fibers are then stamped to produce the desired final shape. A method is suggested which combines the stamping and cutting of the fibers into one single manufacturing step. For this purpose, the upper or lower cutting blades are provided with a respective cutting contour which corresponds to the desired final shape. The cutting edge contour has a parallel leading center section in the direction of cutting that is parallel to the surface of the sheet steel. The two end sections are recessed and have a wave-shape or flat S-shape. When using a rotating cutting tool the rotating roller may have axially adjacent individual groups of upper cutting blades so that from the end face of an undivided sheet steel a corresponding number of adjacent steel fibers may be produced in a combined stamping and cutting step.
