ABSTRACT:
The present invention relates to a process for controlling the temperature of a product in the form of a web (12) that is influenced by an IR ramp (9) for surface treatment of the web (12). With the help of a number of temperature sensors (26), the temperature of the web (12) is measured continuously within evenly distributed zones across and along its direction of movement (28), and the values obtained from the respective zone of the web (12) are transmitted to the respective drier modules (2) 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.
