Abstract: An apparatus for disintegrating a carbon fiber fabric. The apparatus includes a water vessel containing water, with an ultrasonic wave oscillator immersed in the water and a guide plate for the fabric being located in opposed relation to the oscillator. A conveyor is provided for continuously conveying the carbon fiber fabric along the side of the guide plate facing the oscillator. Sound waves generated by the oscillator function to press the carbon fiber fabric against the guide plate in a manner as to cause the fabric to be disintegrated under the effects of the ultrasonic waves.

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.
