    • A method and a device (1) to treat a paper web (12) by using air, which flows around and cools the infrared lamps (4), to impinge against the paper web and thereafter be removed. A glass plate (9), supported by a pair of glass holders (8), is used to shield the paper web from the infrared lamps. In order to improve the total efficiency and, in particularly, to achieve even and efficient drying of the paper web by using less energy, the cooling air outlets adjacent the glass holders are designed as adjustable width nozzles (19) to direct the heated air against the paper web. The nozzles extend across the entire width of the paper web and the cooling air is ejected from the nozzles at high speed thereby forming an air knife to tear apart the boundary layer of humid air which follows the paper web and subjects the paper web to a more intense heat treatment.

    • An infra-red radiator comprises a ventilated body structure (10) having a cross-web (12), a central leg (14), two side legs (16) and two intermediate support legs (18). Stretched between the legs (14, 16) are two reflectors (24) made of a flexible metal foil material and located in front of IR-lamps (26). Located between reflectors and body structure are ventilating hollows or cavities (36, 38) and channels (40, 57), for cooling or ventilation air, are incorporated in the legs. Inlet channels (40) have upper openings (44) which project cooling air flow along with the rearwardly located surface of the reflector (24), and lower openings (46) which project cooling air flow (52) along the reflector surface located between the reflector (24) and lamp (26). Turbulent cooling air (58) flows in the hollows (36, 38) behind the reflector (24) and passes from inlet openings (54), via laterally offset channels (46) in the support legs (18), to the outlet channels (57) and is exhausted, via openings (50), in the form of a jet or pilot flow (68) which, as a result of an ejector effect, accelerates and amplifies the cooling air flow (52).
