摘要:
A method of producing a reinforcing fiber woven fabric, for producing on a weaving machine a reinforcing fiber woven fabric from wefts of reinforcing fiber yarns and warps of reinforcing fiber yarns, the method comprising providing, on a weft supply passage for supplying a weft from a weft bobbin to the weaving machine, a weft unwinding means for laterally unwinding weft from the weft bobbin, and a weft storing cylinder body for sucking along with air, part of weft thus unwound and directed toward the weaving machine and temporarily storing it therein, contactingly supporting weft, minimized in generation of twist by means of lateral unwinding, by a weft contacting means provided in the weft storing cylinder body while being stored in the weft storing cylinder, and preventing the generation of twist of weft being stored by the supporting; a production device therefore, and a reinforcing fiber woven fabric produced therefrom.
摘要:
A method and apparatus for supplying twist free flat warp containing a plurality of carbon fibers to a plurality of wefts in a weaving loom, wherein the warp is transversely removed from a plurality of bobbins and twisted along a longitudinal travelling direction of the warps so that flat surfaces of individual flat warps are oriented at a right angle to an arranged direction. The plurality of flat warps are reeded to a desired density in relation to the arranged direction. The warps are then twisted along the longitudinal travelling direction so that the flat surfaces of the individual flat warps are oriented to the arranged direction.
