Abstract
This invention relates toa process for manufacturing a ribbon constituted by at least one yarn impregnated with a thermoplastics polymer, wherein the ribbon is obtained by controlled sheathing of the yarn by the thermoplastics polymer, then passage of the yarn thus sheathed between two rollers crushing the yarn while the polymer is in its plastic state. This is obtained either by heating the rollers, or, preferably, by subjecting the polymer to the action of ultra-sounds during its passage between the two rollers.
