    Abstract: Described herein is a formation press for manufacturing a three-dimensional fibrous preform. The press includes a compression zone with an amount of an aqueous slurry of fibrous material. At least two orthogonally disposed compression members are for compressing the material in the compression zone. The compression members are in communication with the compression zone for movement relative to it. The compression members are moveable with sufficient inwardly directed force to compress the material so as to form the three-dimensional perform in the compression zone.

    Abstract: A process for manufacturing fiberboard by preparing a fiber slurry mixture including containing cellulose fibers and water then atomizing a liquid bituminous material, such as asphalt. The liquid bituminous material is atomized by mixing it with a pressurized gas, such as compressed air, forming a mist comprising droplets of bituminous material having a diameter between 20 microns and 50 microns. A water spray solidifies the bituminous material droplets thereby forming bituminous particles which fall into the fiber slurry within the spray chamber. From there the slurry is sheared, dewatered, and dried, forming a finished fiberboard.

    Abstract: A novel glass fiber mat is described herein. The mat includes a plurality of substantially uniformly enmeshed individual filament fibers which comprise at least 70% by weight of the fibrous component of the mat. The mat is further characterized in that less than 20% of the area of the mat are voids which extend through the thickness of the mat, the rest being fibrous material, of said voids, at least 80%, 30% and 10%, have an equivalent diameter whose size is less than about 50 microns, 10 microns and 5 microns, respectively. This mat has an exceedingly high tensile strength both in the machine and the cross-machine directions.

    Abstract: The method of impregnating substantial amounts of asphalt into fiberboard. Melted asphalt having desired properties for use with fiberboard is atomized and then chilled by passage through cold water sprays, and into a cellulose-fiber-containing slurry. The asphalt used has a high penetration at elevated temperatures and is atomized at a lower temperature than is ordinarily utilized in producing atomized asphalt. The slurry may then be pumped into a chest, stored therein, pumped into a deculator, and then to a head box and flowed on to the wire screen of a Fourdrinier machine, forming a wet mat. Or, the asphalt-containing slurry may be further asphalt-enriched by spraying atomized asphalt into it as previously, and then pumped into a chest enroute to a Fourdrinier machine. Water drains through the wire screen, and the mat then goes to the dryer. The slurry-handling and the board-forming steps are conventional.
