ABSTRACT:
A curing oven for impregnated mineral wool in the shape of mats comprises a pair of endless cooperating conveyors facing each other and being arranged in a housing, and on either side of the cooperating parts of conveyors several pressure -- and evacuation chambers are located for feeding hot air through the mat. The pressure -- and evacuation chambers are arranged in such a way that the air can be brought in mutually reverse directions through the mat, and they are designed with a decreasing cross sectional area in the direction away from the induction -- and evacuation ports. The interior spaces of the housing located outside the pressure -- and evacuation chambers are kept at a lower pressure than the ambient pressure by a pump unit.
