Cooling Welded Laminate

EXAIR’s customer quilts two laminates together with ultrasonic welds. The problem that they were having is the material becomes soft and distorts as it is pulled thorough the machine. This produced an unsightly product unacceptable to their customer. Having done this application before, I suggested using a Model 110012 12" (305mm) Super Air Knife to cool the welded area right next to the welding horn. This provided cooling air so that the welded imprint set up quickly. As expected, distortion was eliminated. A side benefit was that they were able to crank up the heat and weld faster, further increasing production.
