Abstract

A method and a device for producing reinforcement fibres and adding them to concrete stuff. The fibres are produced from a continuous wire (6) by means of wire pieces, which form the fibres, being detached consecutively from the wire and then, in turn, by virtue of their kinetic energy, being flung into a mixer in which the concrete stuff is undergoing mixing. A device which is suitable for implementing the method comprises a wire spool which is mounted on a balance and from which the wire (6) runs to a wire-impelling unit (4), after which a fibre-detaching unit (8) is arranged which engages with the wire which has been fed forward by the impelling unit and consecutively detaches wire pieces from the wire. The fibres which have thus been detached pass through a nozzle tube (46) which is arranged downstream of the detaching unit (8) and which guides the fibres into a subsequent mixer which contains concrete stuff. The wire-impelling unit (4) and the fibre-detaching unit (8) each comprise a driven wheel (10 and 28, respectively), which engages with the wire, and a guide roller (12 and 30, respectively) which interacts with this wheel.
