Abstract
This invention relates to a tubular apparatus for UV curing coatings on a continuous filament in which concentric tubes are provided and through which the filament passes after being coated for curing the coating, with the apparatus having the first inner tube which passes the UV light through the tube to cure the filament passing therethrough, and a second concentric tube superposed over the first tube and spaced therefrom which reflects IR light and passes UV light to prevent burning and destroying the coating on the filament as it passes through the first tube.
