Abstract
Ultraviolet air float bar for use in floating and drying a continuous planar web of a material in a dryer. Direct radiated or reflected ultraviolet electromagnetic energy from an ultraviolet 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 ultraviolet air float bar either by ultraviolet electromagnetic energy, or in combination with Coanda air flow. The ultraviolet bulb is cooled by pressurized air passing through an interior portion of the removable air bar channel.
