Super Air Knife Cools Specialty Paper Roller

Customer makes special paper products. One of their products is a thin tissue like sheet. The process to make it involves spraying a paper pulp mixture with a proprietary synthetic bacteria absorbing fiber onto a web carrier. The web passes under curing lamps to activate and solidify the substrate. When the web is stopped for adjustments, the heat causes the carrier rolls to develop flat spots at points of contact with the web. When the process starts back up, the flat spots cause vibration on the web, adversely affecting the process. A Model 110054 54" (1372mm) Super Air Knife was installed to provide a cooling air flow whenever the web is stopped, so the rolls so as they are less prone to deformation.
