Abstract
A method and apparatus for feeding a weft to weave a carbon fiber fabric. A carbon fiber package is supported rotatably in such a manner that the axis of the shaft thereof is substantially perpendicular to the running direction of the carbon fiber. The package is rotated so as to deliver the carbon fiber of a prescribed length necessary for one shot weaving of the weft. The carbon fiber of the prescribed length is reserved in a reservoir under an adjusted constant tension before shooting the carbon fiber weft of the prescribed length.
