Abstract
[PROBLEMS] To provide a method for manufacturing a rust preventive coated PC strand, which, simultaneously with working into a PC strand, can realize filling of internal voids in an easy and reliable manner and can realize a good yield and low cost. [MEANS FOR SOLVING PROBLEMS] At least a core wire in each single strand constituting a steel twisted wire is preheated just before a twisting position, and a rust preventive material formed of a heat melted thermoplastic synthetic resin is supplied to the twisting position in the twisting to fill the voids between the single strands in the steel twisted wire. After twisting, the PC strand is subjected to heat treatment such as bluing and/or heat stretching, and the periphery of the steel twisted wire is covered with the rust preventive material formed of a thermoplastic synthetic resin.
