The steel wire 1 to be coated with rubber is pre-heated by passing through the first electro-magnetic induction heating device 10 , the pre-heated steel wire is forwarded to the calendar device 30 and after coating both surfaces of the respective sides of the steel wire 1 with rubber layers through the calendar device 30 , thus coated steel wire 1 with the rubber 2 is subjected again to the electro-magnetic induction heating by means of the second electro-magnetic induction heating device 20 placed at a position after the calendar device 30 thereby intensifying the adhesive strength between the steel wire 1 and the rubber in the vicinity of the boundary surface at the steel wire 1 so as to enhance the improvement of the adhesive strength between the steel code.steel wire and the rubber with which the foregoing is coated.
