Abstract
The invention relates to an apparatus and process for the direct production of a composite yarn or ribbon of continuous reinforcement fibers and a thermoplastic organic material. The process includes drawing reinforcement fibers from molten glass, driving or extruding a thermoplastic organic material, converging the paths followed by the reinforcement fibers and the organic material toward one another, and joining the organic material and fibers in at least one composite yarn or ribbon. An apparatus for conducting this process is also disclosed.
