A method for drying and/or curing a traveling web including a RF generating means for delivering RF through field and RF stray field to the web to heat the web, air bars to direct air flow to the web for cooling to facilitate emission of moisture therefrom and to avoid blistering due to overheating, an RF field generator to reflect RF energy to the web, 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.

Apparatus and method for drying or curing web materials and coatings

An apparatus for forming bands of reduced coat weight of a coating on a coated web that is moving through a laminating machine includes a supply of fluid and a nozzle for directing a stream of fluid from the supply toward the web, said nozzle having a relatively small outlet aperture for directing a relatively narrow width stream of fluid toward the web compared to the width of the web to impinge on the web to reduce the coat weight over a relatively narrow width band. The bands may be formed in the machine direction of travel of the web, across the width of the web in a direction other than the machine direction and may be of various width and may be precisely or randomly placed. The reduced coat weight areas may be narrow bands or broader areas of the web. A method for forming a band of reduced coat weight of a coating on a coated web includes directing a stream of fluid toward the web and extending over a relatively narrow width of the web compared to the width of the web to impinge on the web to reduce the coat weight over a relatively narrow width band or over a relatively broader area of the web.

Method and apparatus for selectively removing or displacing a fluid on a

A radio frequency (RF) assisted flotation air bar dryer apparatus and method for drying and/or curing a traveling web includes RF generating means for delivering RF through field and RF stray field to the web to heat the web, air bars to direct air flow to the web 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, 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 avoid damage to the web.
