Abstract: A method for manufacturing a shaped panel from a continuous length of an expanded mat. The method includes transporting an expanded mat on a conveyor. The conveyor includes side chains and a plurality of spaced apart slats, which extend transversely between the side chains, on which the expanded mat is supported. The side chains and the plurality of slats define a plurality of openings in the conveyor. A length of the expanded mat is confined and shaped between a male mold and a female mold by moving the male mold and the female mold into mating relationship through one of the plurality of openings in the conveyor.

Abstract: A panel is formed from an expanded mat of fiberglass strands, a thermosetting resin binder is incorporated with these strands. When the panel is formed, it has a relief between the edges of the panel and the recessed portion of the panel. The panel is retained in its molded position by the setting of the thermosetting resin binder.
