The present invention relates to a process for controlling the temperature of a product in the form of a web () that is influenced by an IR ramp () for surface treatment of the web (). With the help of a number of temperature sensors (), the temperature of the web () is measured continuously within evenly distributed zones across and along its direction of movement (), and the values obtained from the respective zone of the web () are transmitted to the respective drier modules () for the purpose of subjecting the aforementioned zones of the web to heat. The invention also relates to an arrangement with which the aforementioned process is executed.

Process for controlling the temperature of a web and a device to use for said temperature control

The present invention relates to an infra-red radiation device comprising a shell or reflector body and holders mounted on the ends thereof, and also holders for accommodating IR-lamps. Each shell or body includes a plurality of individual reflector parts comprising reflector plates preferably of parabola shape. The body holder comprises a web and a recumbent U-shaped element, located at the end of the body adjacent the open reflector side. The free leg of the U-shaped element includes a glass holder in which a glass plate can be inserted, to insulate IR-lamps from dust and dirt. The U-shaped element is provided with holes for screws. The holder or reflector and/or the body holder includes, or include, air gaps or holes intended for cooling air, which preferably cools the ends of the lamps.
