Client Request: Provide equal tension on double face liner, thus providing consistent temperature across the same liner as it leaves the triple stack preheater. Solution: Install a Compensating Roll on the Preheater wrap arm. Results: Achieved equal tension on the liner by compensating for the worn gears in the wrap arm assembly. With consistent wrap being applied across the web, this provides for uniform heat transfer from the Preheater to the liner with temperature variation less than 5 degrees.
