ABSTRACT:
An improved apparatus for curing fibrous insulation material includes an oven, and a lower conveyor mounted to travel through the oven. The lower conveyor includes a plurality of flights having a support surface for supporting fibrous insulation material. An upper conveyor is mounted to travel through the oven and has a plurality of flights opposite the flights of the lower conveyor. Each flight of the upper conveyor includes a support surface. The upper and lower conveyors are arranged to press the fibrous insulation material between the respective support surfaces as the conveyors carry the fibrous insulation material through the oven. A plurality of molding members are configured to mold a shape into a surface of the fibrous insulation material, and are releasably retained on the flights by a plurality of retaining members. The retaining members are automatically releasable when the flights are moving, such that the releasing of the retaining members unlocks the molding members from the flights.
