ABSTRACT:
A method and apparatus for supplying twist free flat weft containing a plurality of carbon fibers to a plurality of warps in a rapier weaving loom wherein the weft is transversely removed from a bobbin by draw-off rollers and intermittently supplied to the rapier. An elastic force is applied to the length of weft accumulated between the rapier and the bobbin to take up any slack and obviate its twisting. By this technique a carbon fiber fabric is woven with flat wefts which ensure a high fabric strength since crimped yarns with non uniform densities are avoided as well as a non uniform fabric thickness caused by irregular yarn thicknesses.
