Abstract

Abstract Curing and drying apparatus for printing inks which includes a housing having openings for passing a printed web therethrough and lamp assemblies each including a shell, a reflector, and an ultraviolet light lamp or radiator for focusing radiation onto said web. Blowers are coupled to said housing for feeding air about the back side of said reflectors and about the sockets for the lamps to remove excess heat and means are provided for protecting said lamps from said cooling air to prevent lowering the temperature and therefor the efficiency of the lamps. The lamp assemblies are rotatable to and from an operating position and when out of the operating position the radiation is directed into cooled radiation absorbing chambers which permit the lamps to remain energized without damaging the web should movement of the latter be temporarily stopped because of the need for stopping the associated printing press.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 144 words
Ink curing apparatus comprising a housing having openings for feeding a web therethrough, an ultra-violet lamp assembly rotatably supported within said housing and positioned transversely of said web, said assembly including an elongated shell having an opening extending longitudinally thereof, an elongated reflector and ultra-violet lamp within said shell, said lamp and reflector being positioned within said housing to direct radiation through said opening, said lamp being of cylindrical configuration having neck portions extending therefrom and terminals on said neck portions, sockets carried on each end of said assembly for engaging said terminals, transverse plates within said shell each having an opening therein, said plates being positioned with said necks extending through the plate openings and means carried by said plates and sealing said plate opening about said neck portions whereby said neck portions and sockets can be air cooled without cooling said lamps.
