A method and fiber-placement head are provided for placing fibers (33) into a plurality of channels (11) of a mold (10) to form the ribs of a structural member, including panels, cylinders and cones, or even a ribbed latticework structure by itself. While providing relative movement between the mold (10) and a plurality of fiber placement heads (22), fibers (33) are simultaneously placed into a number of the channels (11) of a mold (10) by means of the heads (22). The relative movement and placement is repeated as often as necessary in order to dispose into the channels (11) a desired thickness of the fibers (33). Each head (22) has a single motor-driven wheel (37) for continuously withdrawing the fibers (33) from a supply means (26) and feeding the fibers (33) through the head (22).
L'invention concerne un procédé et une tête servant à placer des fibres (33) dans plusieurs canaux (11) d'un moule (10) pour former les renforts d'un élément structurel, y compris des panneaux, des cylindres et des cônes, ou même une structure en treillis renforcée. Causant un mouvement relatif entre le moule (10) et plusieurs têtes (22) servant à la mise en place des fibres, les fibres (33) sont simultanément placées dans un certain nombre de canaux (11) d'un moule (10) à l'aide des têtes (22). Le mouvement relatif et la mise en place sont répétés aussi souvent que nécessaire pour placer dans les canaux (11) une épaisseur désirée de fibres (33). Chaque tête (22) possède une roue unique motorisée (37) servant à retirer de façon continue les fibres (33) d'une unité (26) d'alimentation, et à insérer les fibres (33) dans la tête (22).
