Abstract
A PC strand is coated with rust inhibitive material of thermoplastic resin so as to wholly close spaces left around a core and peripheral wires twisted around the core, thus preventing the core and wires from rusting. The strand coated with the rust inhibitive material can be produced without being untwisted by use of an extruding machine having an auxiliary pressure head connected to a cross head.
