ABSTRACT:
For a workpiece having a metal part bonded to a rubber part, a method is devised to separate the metal and rubber parts. A flame is used to heat a portion of an exposed surface of the metal part, while moving the flame relative to the metal part until substantially all the exposed metal surface is heated. The process is repeated until the metal and rubber parts separate.
