Abstract
A method and apparatus is disclosed for producing a spun yarn composed of an inner substantially untwisted core having fibers spirally wrapped about the surface thereof. In a specifically illustrated embodiment, a yarn of staple fibers is advanced along a path of travel, while being laterally deflected by contact with each of three separate rotating discs, and so as to produce a rotating balloon which serves to open the yarn and loosen and separate fibers on the surface of the yarn. Subsequently, the advancing yarn is subjected to a false twisting operation, which serves to wrap the loosened fibers about the advancing yarn.
