Abstract
A method for baking a continuous mat of mineral or plant fibers successively includes application of an aqueous solution, containing a binder diluted in the solution, onto mineral or plant fibers, shaping of the fibers to form a continuous mat on a conveyor in motion, and heating the mat in movement through an oven by a hot air flow at a temperature higher than the curing temperature of the binder. Furthermore, at least partial drying of the mat is carried out before entry into the oven. The at least partial drying includes irradiation of the mat in movement with radiofrequency electromagnetic waves whose frequency lies between 3 MHz and 300 GHz.
