A method and a device for processing a metal wire so that it can effectively be applied to a matrix as fiber reinforcement, thereby contributing the strength of the fiber material to the matrix. A typical example of a matrix material is concrete. This invention operates in principle in the following way according to Fig. 1: rollers (1', 1'') drive the wire (2) from the reel (3) to a cutting mechanism (10) with one fixed (7) and one or more rotating cutters (8, 15), where the wire is cut into fibers (12) which are then sprayed at high speed onto the surface of the concrete for embedding in the matrix material, The advantage of this invention is that the concrete manufacturer can use wire supplied on reel or a similar paying-off device and, with the aid of a device according to this invention, apply directly to the concrete material fibers of greater length and more accurate distribution than previously obtainable with other devices. |
