Title (EN) DEVICE FOR WIRE PROCESSING
(FR) DISPOSITIF DE TRAITEMENT D"UN FIL
Abstract: front page image
(EN)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.
(FR)Procede et dispositif de traitement d"un fil permettant d"utiliser ce dernier dans une matrice a titre de fibre de renforcement, contribuant ainsi par la resistance mecanique de la fibre a la solidite de la matrice. Le beton est un exemple typique d"un telle matrice. Le principe de l"invention est illustre comme suit a la figure 1: les rouleaux (1, 1") entrainent le fil (2) depuis la bobine (3) jusqu"a un dispositif de coupe 10 comportant un couteau fixe (7) et un ou plusieurs couteaux rotatifs (8, 15), dispositif dans lequel le fil est decoupe en fibres (12) qui sont ensuite dispersees a grande vitesse sur la surface du beton et sont noyes dans le materiau formant matrice. Cette invention presente l"avantage de permettre au fabricant de beton l"utilisation de fil livre sur bobine ou sur un dispositif de distribution de type similaire et, grace au dispositif selon l"invention, d"ajouter au beton des fibres plus longues qu"avec les autres dispositifs tout en conservant une distribution plus precise.
