An ejection nozzle for transport of fibre thread pieces by means of com-pressed air, e.g. reinforcement material for manufacturing fibre reinforced plastic products, from a cutter to a moulding cavity. The nozzle is provided with a common flow duct for the compressed air and the fibre thread pieces. The flow duct runs past at least one reflector surface (15) for the air flow, and at least one opening (16) for evacuation of air to the surroundings is located along the flow duct.

La présente invention concerne une buse d'éjection destinée à entraîner par air comprimé des fragments de fils de substance fibreuse, par exemple, le matériau de renforcement destiné aux produits en plastique renforcé par des fibres, d'un outil de coupe vers une cavité de moulage. La buse comporte un conduit d'écoulement commun destiné à l'air comprimé et aux fragments de fils de substance fibreuse. Le conduit d'écoulement passe par au moins une surface de renvoi (15) d'écoulement d'air. Le conduit d'écoulement présente sur sa longueur au moins un orifice (16) évacuant l'air vers l'extérieur.
