Abstract
Monofilament threads which are wound around a thermoplastic synethetic resin core tube to form one or more reinforcement coils are generated as they are wrapped around the core tube by liquid crystalline polymer material emerging from respective spinning nozzles which rotate around the core tube while a difference in speed is maintained between the speed at which the reinforcing plastic emerges from the nozzle and the monofilament thread is wound on the core tube to maintain a stretch in the monofilaments.
