ABSTRACT:
A machine that receives freshly printed matter, and moves the printed matter on a belt along the machine so that the printed matter passes through an irradiation chamber where it is irradiated with ultraviolet light. The printed matter continues to move along the belt and is thereby removed from the irradiation chamber and delivered to the output end of the machine. The irradiation chamber is so constructed so as to control the intensity of the ultraviolet radiation that is delivered to the printed matter. Air moving means are also provided by which to control the maximum temperatures induced in the printed matter as it passes through the irradiation chamber. Another air moving means is employed to control the temperature of a radiator assembly employed within the irradiation chamber. A third air moving means is provided to evacuate the irradiation chamber and associated components of hot and contaminated air and to exhaust this air to the outside.
