The present invention provides a method of removing metal wires from a tire through induction heating, a method of collecting the metal wires and rubber part, and a method of reusing the metal wires and rubber part. The present invention relates to: a metal wire removal method for removing metal wires from a tire incorporated with metal wires using induction heating, wherein the metal wires in the tire are heated by induction heating, causing the rubber in the part contacting the metal wires to decompose and gasify to separate the metal wires and rubber part, whereupon the metal wires are removed; a method of collecting the metal wires and rubber part from the tire using the method described above; and a method of reusing the metal wires and rubber part collected using the method described above as metal and rubber resources. Thus the metal wires and rubber part can be separated from a used tire, collected at a high collection rate, and reused.
A metal wire removal method for removing metal wires from a tire incorporated with metal wires using induction heating, which comprises heating the metal wires in the tire by induction heating, thereby altering the characteristic of the rubber part contacting the metal wires of the tire to separate the metal wires and the rubber part, and then removing the metal wires therefrom.
A bead wire removal method characterized in that a sidewall portion and a bead portion separated from a tire are placed onto fixing means and fixed thereby, the bead wires in the bead portion are subjected to induction heating, the rubber covering the bead portion is cut away, and then the bead wires are separated from the bead portion.
