COATING DRYER HEATING SYSTEM

摘要

The present invention is a dryer system (10) for drying coatings applied to a substrate (12), which includes means for impinging the substrate with heated air, a thermally conductive roll (22) having a length and a peripheral surface (35) for supporting the substrate, and a plurality of energy emitters (44) disposed within the conductive roll along the length of the roll. A housing extends about at least a portion of the roll (22), and the housing has an arcuate panel member radially spaced from the circumferential outer surface of the roll. The arcuate panel member has a plurality of alternating rows of coaxial extending outlet slots and recessed troughs (72). A blower and plenum assembly (36) is disposed in the system housing, and axially extending carbon emitter lamps (84) and radiant energy reflective members (82) are mounted within selected troughs (72). A preheating station (41) is disposed proximate the substrate.
