ABSTRACT:
The method of producing reinforced thread includes feeding loose fibres o the disc of a rotary twisting member, guiding the core thread through the disc eccentrically with respect to the axis of rotation of the twisting member and conducting the winding of the fibres about the core thread, to form the reinforced thread by rotating the twisting member. The apparatus for performing the method of producing reinforced thread comprises fibre-separating means communicating with a twisting member having a flat disc with an axial bore and an opening for the passage of the core thread, arranged eccentrically with respect to the axis of rotation of the twisting member, a holder for a bobbin with the core thread, a unit for winding the reinforced thread, and a guide for the core thread having its geometric center overlying the plane of the disc and aligned with the axis of rotation of the twisting member.
