Abstract
A method for making an article including an elongated member and a tape member bonded to the elongated member. An elongated member is extruded from at least one rubber in a continuous manner, then continuously vulcanized. A tape member including at least one resin layer with a melting temperature that is lower than a temperature of the elongated member immediately after vulcanization is separately supplied and preheated to about the softening temperature of the resin layer. The preheated tape member is then continuously contacted with and pressed against the vulcanized elongated member to thereby at least temporarily fix the elongated member to the tape member at opposing surfaces. Contact between the elongated member and the tape member is maintained for a sufficient period of time to cause heat remaining in the elongated member from the vulcanizing step to melt at least the opposing surface of the tape member. The tape member is continuously pressed against the elongated member while removing heat from the tape member to thereby fusion bond the tape member and the elongated member together.
