A method and apparatus are provided for guiding and/or redirecting a filament tow or tape in an automated fiber placement process, through use of a gas bearing having a porous wall defining an internal guide, and/or a channel by means of which the tow or tape is routed and supported by a flow of pressurized gas, such as air or nitrogen, that is fed through the porous wall to create a gas bearing effect for supporting, guiding, and redirecting the tow or tape within the tubular bushing in such a manner that contact between the tow or tape. A porous section of the gas bearing may be constructed layer- by-layer by a process such as stereolithography.
La présente invention a trait à un procédé et un appareil pour l'orientation et/ou la réorientation d'un câble ou ruban de filaments dans un procédé automatisé de pose de fibres, grâce à l'utilisation d'un palier fluide ayant une paroi poreuse définissant un angle intérieur, et/ou un passage à l'aide duquel le câble ou ruban est acheminé et supporté par un flux de gaz sous pression, tel que l'air ou l'azote, qui est alimenté à travers la paroi poreuse pour la génération d'un effet de palier fluide pour le support, l'orientation et la réorientation du câble ou ruban au sein d'une fourrure de forme tubulaire qui est en contact entre le câble ou ruban. Une section poreuse du palier fluide peut être construite couche par couche par un procédé tel que la stéréolithographie.
