ABSTRACT:
A process for forming a mineral wool, resin-bound acoustical insulating fiberboard product is described, which includes steps for mixing mineral wool fibers and powdered thermosetting binder, the introduction of the mixture into an air stream, and the directing of the entrained mixture into a mat-forming zone formed by converging upper and lower forming wires, the exhausting of air through the wires to build up layers of fiber and binder thereon and the consolidation and heating of the layers to form a fiberboard product, the amounts of air exhausted through the forming wires being adjusted so that a resin-enriched layer of predominantly fine fibers is initially deposited on the upper forming wire. A preferred embodiment is disclosed wherein an open mesh glass fabric is positioned between the lower forming wire and the layer of fibers and resins being formed thereover, said fabric acting as a carrier for the board-forming mat.
