  • Patent number: 5930914
    Abstract: A method and device for drying a moving web including a first infrared radiator arranged on a first side of the web and a second infrared radiator arranged on a second side of the web at least partially opposite to the first infrared radiator and proximate to the first infrared radiator. The wavelength of the maximum intensity of the radiation generated by the first infrared radiator is shorter than the wavelength of the maximum intensity of the radiation generated by the second infrared radiator. The power density of the first infrared radiator is from about 450 kW per sq.m to about 700 kW per sq.m and the emitter temperature of the first infrared radiator is from about 2000.degree. C. to about 2800.degree. C. The second infrared radiator includes a surface layer made of a metal, metal alloy or ceramic material whose emissivity is substantially equal to or higher than about 0.6.
