Abstract: An infrared drying system for monitoring the temperature, moisture content, or other physical property at particular zone positions along the width of a traveling web, and utilizing a computer control system to energize and control for finite time periods a plurality of infrared lamps for equalizing physical property and drying the web. The infrared drying system is particularly useful in the graphic arts industry, the coating industry and the paper industry, as well as any other applications requiring physical property profiling and drying of the width of a traveling web of material. The infrared drying system profiles a physical property across the width of the web by a sensor head which travels on a belt supported above the web, and inputs the information into a computer to generate signals corresponding to the measured physical property for each particular segment portion along the width of the web above or below a setpoint.

Abstract: Ultraviolet radiating means for curing and drying non-solvent ink which has been applied to a substrate during a printing or coating process, the radiating means including a plurality of elongated parallel ultraviolet lamp assemblies mounted to radiate against the non-solvent ink as the substrates are passed in front of the lamp assemblies. The lamp assemblies are slideably mounted in side by side relation in a module which is in turn slideably received in a housing. The lamp assemblies each include an ultraviolet lamp mounted in a elongated reflector shaped to reflect the ultraviolet radiation emitted from the lamp and to focus it to form a narrow band. The lamp assemblies are mounted in the housing so as to be freely rotatable from a curing position to a position where they are directed toward a heat exchanger. The lamp assemblies may also be mounted so that a pair of the lamps will direct ultraviolet radiation at the same area on the substrate.
