  • Patent number: 4839522
    Abstract: Disclosed is an apparatus for curing ink on the exterior surface of an article preferably with ultraviolet radiation. A conveyor transports the article along an enclosed path within a housing having a wrap-around reflector which provides indirect stray light about the 360.degree. circumference of the article. The interior reflective surface within the housing is preferably dimpled to cause the light to scatter in every direction and to provide indirect substantial uniform light intensity about the curcumference and the top of the article, i.e. uniform and indirect radiation over substantially the entire exposed surface of the article, without requiring rotation or other manipulation of the article. The preferred wrap-around reflector includes reflective specular surfaces on the front and rear walls of the housing as well as the corners of the housing where these walls join the side and top walls of the housing.
