Abstract
This invention relates to methods of making metal fibers and devices for effecting such methods. A method of making metal fibers from spherical particles (6) of a metal powder to be practiced by an apparatus for making such metal fibers is proposed, the method residing in that the spherical particles (6) of metal powder are deformed by rolling each such spherical particle (6) along the path of the process and stretching this particle (6) along its axis of rotation between a main roll (2) and an additional roll (3) of a deforming tool (1). The stretching is executed at a rate exceeding the rate of plastic flow of metal in elongation during reducing the diameter of the deformable spherical particle (6), the additional roll (3) being used as a stretching device. The ready metal fibers (7) are then discharged.
