ABSTRACT:
A slubbing is formed into a thin band by a plurality of pairs of rollers. A core filament is thereafter applied to each face of this band and the two core filaments and band are then spun together to form a core yarn comprising a coherent mass of fibers in which is imbedded a pair of parallel and spaced apart core filaments with some of the fibers of the mass between the spaced-apart filaments.
