Fiber for reinforcing concrete or similar materials made of wire of a flat material strip and device for manufacturing such fibers

摘要

A fiber for reinforcing concrete is manufactured from wire or flat bands and has a linear center section and a first intermediate section connected to the first end of the center section and a second intermediate section connected to the second end of the center section. The first and the second intermediate sections have a wavy shape and are shorter than the center section. A first end section is connected to the first intermediate section and a second end section is connected to the second intermediate section. The first and the second intermediate sections preferably have an elongated S-shaped deformation extending in a common plane. The first and the second end sections are substantially linear and extend parallel displaced to the center section. The fibers are produced in one stamping operation in an inexpensive manner.
