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. A control computer generates signals corresponding to the particular segment portion of the web and the particular power to be applied to heat that segment portion of the web. A lamp control computer controls lamps in opposing lamp units, through power controller signals for energizing individual infrared heating lamps for finite time periods during each power cycle for drying the traveling web.
