  • Patent number: 5529094
    Abstract: A method and apparatus is provided for manufacturing a carbon fiber woven fabric by opening and closing a warp sheet formed of carbon fiber warps and by injecting wefts made of carbon fibers by water-jet into the warp sheet when the warp sheet is open. The accumulation of fluffs generated by abrasion between the weft and various guides is reduced by interrupting dispersion of water injected from the nozzle onto the weft as the weft travels from a bobbin to the nozzle, by sucking fluffs from the weft, and/or by causing contact between the weft and fluffs on the surface of the nozzle by loosening the weft, thereby making it possible to conduct a high-speed continuous operation.
