Ultraviolet light apparatus

Claim 1

Apparatus for curing ink or coatings on a cylindrical container comprising: (a) a frame; (b) a wheel, mounted on said frame for rotation about an axis; (c) a reflector, affixed to said wheel for movement therewith about said axis, said axis being co-incident with a first focus of said reflector and wherein a second focus is outward thereof; (d) a radiant energy source fixedly mounted on said frame, substantially co-extensive with said reflector and disposed at said first reflector focus; (e) a belt disposed to engage said wheel at the circumference and drive said wheel, said belt including a plurality of carriers mounted thereon for (one of said carriers) supporting and (maintaining said container in confronting alignment with said reflector) conveying said containers, said carriers being disposed along said belt at intervals equal to the circumference of said wheel, said belt engaging said wheel to advance said carriers into individual registration with said reflector wherein said container mounted on said registered carrier is substantially co-extensive with said energy source and is confrontingly aligned with said reflector whereby said confrontingly aligned container intercepts rays from said reflector, proximate the second focus of said reflector, and wherein said rays are maintained substantially in focus on said confrontingly aligned containers as said confrontingly aligned container moves around said energy source; and (f) means for rotating said carriers as said carriers move around said energy source thereby ensuring uniform irradiation of said confrontingly aligned container by said focused rays of energy.
