Title:
空気浄化シャッターを有する赤外線乾燥機
Document Type and Number:
Japanese Patent JP4384365
Kind Code:
B2
Abstract:
A combination infrared/air convection dryer or oven for travelling webs. A shutter assembly is provided between the infrared radiation source and the moving web in order to selectively expose the web to infrared radiation, and to create a sealed air chamber when in the closed position. Enhanced drying of the web and/or a coating on the web at high speed is achieved without a concomitant increase in dryer length. When the drying atmosphere has a high concentration of solvent, exposure of that atmosphere to the heating elements, which can cause explosions, is eliminated by actuation of the shutters. In a preferred embodiment of the invention, air bars are used to floatingly support the moving web to avoid contact of the web with dryer elements.
