Title
(EN) METHOD FOR DISPENSING REINFORCEMENT FIBERS
(FR) PROCEDE DE DISTRIBUTION DE FIBRES DE RENFORCEMENT
Abstract
(EN)
A method for dispensing reinforcement fibers (12) to make a preform or laminate includes winding a continuous length of a reinforcement fiber (16) into coils (28) around a form (26, 42, 50) having a longitudinal axis (30), moving the coils (28) axially with respect to the form (26, 42, 50) to engage a cutter (36, 46), cutting the coils (28) to form discrete length reinforcement fibers (12), and dispensing the discrete length reinforcement fibers (12).
(FR)
La présent invention décrit un procédé de distribution de fibres de renforcement (12) permettant de fabriquer une préforme ou un stratifié, consistant à enrouler une longueur ininterrompue d'une fibre de renforcement (16) en bobines (28) autour d'une forme (26, 42, 50) comportant un axe longitudinal (30), à déplacer axialement les bobines (28) par rapport à la forme (26, 42, 50) afin de les mettre en contact avec un organe de coupe (36, 46), à couper les bobines (28) pour obtenir des longueurs de fibres de renforcement (12) séparées, et à distribuer ces longueurs de fibres de renforcement (12) séparées.
