1. A method of manufacturing a core yarn in which two rovings of fibres are separately drawn between a supply place and a pair of drawin rollers upstream of which a continuous filament is inserted into each roving, the two strands each formed by the roving of fibres and the continuous filament are twisted together by a false twisting means (7) by inserting them at the same convergence point (12) upstream of the false twisting means, the tension of the strands is adjusted, the strands are wound, and the resulting yarn is twisted on a twisting loom.
