Da Inglese a Italiano Legale/Brevetti Ingegneria (generale) air flow regulation

Air float bars for use in positioning, drying or curing a continuous generally planar flexible mate-rial such as a web, printed web, newsprint, film ma-terial, or plastic sheet are disclosed in this appli-cation. More particularly, they pertain to an air float bar whose pressure pad area includes an infra-red light source, such as an infrared bulb, a reflec-tor surface and a lens to enhance accelerated infra-red heating of web material to cause solvent evapora-tion, drying and/or curing.

Even with such quick cooling emitters, it is de-sirable to keep the exposed surfaces of the air float bar as cool as possible at all times to prevent possible ignition of said combustible materials, even when web stoppage or a web breakage upset may go undetected.


Direct radiated or reflected infrared electromagnetic energy from an infrared bulb in a removable air bar channel assembly accelerates drying, or evaporation of solvents, or curing of planar web material passing in proximity to the infrared air float bar either by infrared electromagnetic energy, or in combination with Coanda air flow.
