ABSTRACT:
A method for recovering metal reinforcement from rubber tires involves placing a tire having metal reinforcement into a high-frequency electromagnetic field, heating the tire and separating the reinforcement from rubber. Lowering of power requirements and enlargement of capabilities are achieved by clamping the tire between rolls and subsequent heating of a local portion of the tire to a temperature of pyrolysis of rubber layers nearest to the reinforcement to form a pyrolysis swelling. The tire is then drawn between the rolls.
