description An infrared inspection system (32) and an induction heating system (12) used in conjunction enable the inspection of rubber coated rolls (14), such as rolls used in the pulp and paper industry. The system effects non-destructive inspections of rubber coated rolls to detect a debonded condition between the metal core and rubber coating. The method includes supporting (30) a roll for inspection, evenly heating (16,18) or cooling the roll, and observing a thermal transient of the roll generated by the even heating process. Using an infrared camera (32), observed areas that are not transferring heat uniformly with respect to neighboring areas are suspected debonded areas.
