ABSTRACT:
For heat treating products having a substantially circular cross section and being composed of mineral fibers containing a binder in solution in water, a metal container impervious to microwaves and equipped with a conveyor device includes a source of hot gas which is directed to the surface of the product. The conveyor in the form of a movable belt and a ceiling of fixed plates cooperate to roll the products during transport through the container so that their displacement is half of the speed of the belt.
