System and method for detecting debonding in rubber coated rolls

The present invention relates to a system and method for rubber coated roll inspection and, more particularly, to an infrared inspection system cooperating with an induction heating system for non-destructive inspections of rubber coated rolls looking for de bonds between the metal core and rubber coating. An infrared inspection system and an induction heating system used in conjunction enable the inspection of rubber coated rolls, 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 a roll for inspection, evenly heating or cooling the roll, and observing a thermal transient of the roll generated by the evenly heating process. Using an infrared camera, observed areas that are not transferring heat uniformly with respect to neighboring areas are suspected debonded areas.
