The invention relates to a method for producing a fibre layer with a longitudinal direction, wherein the method is based on the fact that fibre bundles having the same or a different fibre fineness which are guided in parallel are guided together in an overspread, overlapping manner and as a result are mechanically strengthened, wherein at least one sliver is obtained as a unidirectional layer with a defined width without additional fixing agent and/or additional mechanical or physical fixing methods.

L'invention concerne un procédé pour produire une couche fibreuse ayant une direction longitudinale. Le procédé selon l'invention consiste à écarter des faisceaux de fibres conduits en parallèle et présentant une finesse de fibres identique ou différente, à les rassembler en les chevauchant et à les consolider ainsi mécaniquement. On obtient ainsi au moins une bande fibreuse sous forme de couche unidirectionnelle de largeur définie, et ce sans agent de fixation supplémentaire ni méthodes de fixation mécaniques ou physiques supplémentaires.
