Abstract
A process for manufacturing a composite yarn including continuous glass filaments intermingled with continuous organic thermoplastic filaments and an apparatus for implements the process. The continuous glass filaments coming from a bushing and are separated into several sheets. The continuous organic thermoplastic filaments come from a spinning head are separated into plural sheets. And the thermoplastic filaments are thrown into the glass filaments so as to mingle them, in a ratio of at least one sheet of thermoplastic filaments in each sheet of glass filaments, the mingled filaments then being gathered into at least one composite yarn.
