CA 2579486

The invention relates to a method for curing a binder on a fibre insulation (108), consisting in flowing a hot gas according to a rate ratio between an upward flowing in said fibre insulation (108) and a downward flowing therein in order to heat the binder to a curing temperature thereof and in cooling said binder in such a way that at least one part thereof is cured to a thermoset state thereof. If a part of the binder is not yet cured, another binder heating stage carried out at a rate ratio between the hot gases and followed by cooling is used for curing the reminder of the binder.

L'invention concerne le durcissement d'un liant sur un isolant fibreux (108), dans lequel un gaz chaud s'écoule sous la forme d'un rapport entre un écoulement vers le haut dans l'isolant fibreux (108) et un écoulement vers le bas dans l'isolant fibreux (108), pour chauffer le liant jusqu'à sa température de durcissement, le liant étant refroidi pour ainsi durcir au moins une partie de liant jusqu'à son état thermodurci. Si une partie du liant n'a pas encore durci, un autre étage de chauffage du liant avec un rapport entre les gaz chauffés, suivie par un refroidissement, durcira le reste du liant.
