ABSTRACT:
An apparatus for heating a sheet- or web-like material during its passage through a processing machine. The apparatus is provided with at least one heating panel which faces the path of travel of the material and is equipped with a number of infrared-radiation producing elements energized from an ac-source. The apparatus comprises a controlling unit for determining the heat released by the heating panel as a function of a control signal generated by a control means. The infrared elements generate short- to medium-wave infrared radiation. The control signal generated by the control means may be a function of the temperature of the material being passed along the heating panel, or a function of the rate of passage of said material.
