Cooling Calendar Rolls

Customer thermoforms using heated calendar rolls. The problem they were experiencing was distortion of the product. Since the web is not as wide as the roll,the heat from the ends is not absorbed. This causes an uneven heating surface, distorting the web. Using a Model 110003 3" (76mm) Aluminum Super Air Knife to blow cooling air on the exposed surfaces of the roll, they were able to remove enough heat to eliminate the product distortion.
