<p>A radio frequency (RF) assisted floatation air bar dryer apparatus (10) and method for drying and/or curing a traveling web (11) includes RF generating means for delivering RF through field and RF stray field to the web (11) to heat the web (11), air bars (21) to direct air flow to the web (11) for cooling to facilitate emission of moisture therefrom and to avoid blistering due to overheating, an RF field reflector to reflect RF energy to the web (11), and a control system to monitor and to control air temperature and/or flow, RF field strength, and/or web temperature to maintain a balance between heating and cooling to obtain efficient high speed drying while avoiding damage to the web (11).</p> |
