In a crimping process of metal fibers between the engaging pairs of gear rollers, the fibers are first embedded in a ductile and coherent matrix material. After applying a permanent crimping wave deformation on this composite, the matrix material is removed. The crimped fibers can subsequently be transformed to a metal fiber web. They can also easily be blended with textile fibers in order to form, e.g., antistatic blended yarn.

A method of manufacturing a gear crimped metal fiber bundle, comprising the steps of: (a) embedding the metal fibers in a ductile and coherent matrix material to form a composite matrix/fiber bundle; (b) passing this composite matrix/fiber bundle between teeth of at least two intermeshing gear rollers provided with parallel axes of rotation, so that the fibers receive a permanent crimping wave deformation; and (c) removing the matrix material.
