Abstract
An improved curing oven using Wellsbach conversion is disclosed. The present invention 10 provides an improved curing oven which cures materials with electromagnetic radiation in the ultraviolet region. The invention consists of a surface 12 lined with a layer of material 14 effective to radiate ultraviolet radiation in response to the application of infrared radiation. In a specific illustrative implementation, the invention 10 includes a second surface 18 overlying the first surface 12 providing a passageway therebetween. The oven temperature is set and maintained by a conventional temperature controller 20. The temperature controller 20 measures the oven temperature and controls a valve 22 which adjusts the gas pressure from a gas supply 24 to a set of oven burners 26. Air is supplied through inlet ports 28 included in the second surface 18.
