Method and device for producing a composite yarn

An apparatus for manufacture of a composite yarn formed by intermingling of continuous glass filaments with continuous organic thermoplastic filaments, comprising:

• at least one bushing fed with molten glass, a lower face of the at least one bushing being provided with a multiplicity of orifices associated with a coater;
• at least one spinning head fed with a molten organic thermoplastic, a lower face of the at least one spinning head being provided with a multiplicity of orifices, associated with a variable-speed drawing device wherein the spinning head extrudes a plurality of bundles of thermoplastic filaments;
• a roll around which the plurality of bundles travel, wherein the roll joins the plurality of bundles into a plurality of sheets of thermoplastic filaments;
• and
• means common to the bushing and to the spinning head, allowing the composite yarn to be assembled and drawn,
• wherein the bushing is associated with means for separating the glass filaments into a plurality of bundles or sheets, and the spinning head is associated with means for mingling the sheets of thermoplastic filaments with the bundles or sheets of continuous glass filaments.
