A method for dispensing reinforcement fibers to make a preform or laminate includes winding a continuous length of a reinforcement fiber ( 16) into coils (28) around a form (52) having a longitudinal axis, moving the coils axially with respect to the form to engage a cutter (60), cutting the coils to form discrete length reinforcement fibers (64), applying a resinous material to the discrete fibers, and dispensing the discrete length reinforcement fibers (78).

Procédé de distribution de fibres de renforcement, pour la fabrication d'une ébauche ou d'un stratifié, consistant à enrouler une longueur continue d'une fibre de renforcement (16) pour former des spirales (28) autour d'une forme (52) présentant un axe longitudinal, à déplacer les spirales axialement par rapport à la forme de sorte qu'elles viennent en contact avec un dispositif de coupe (60), à couper les spirales pour former des longueurs discrètes de fibres de renforcement (64), à appliquer une matière résineuse aux fibres discrètes et à distribuer les longueurs discrètes de fibres de renforcement (78).
