20090025898Process for molding a friction wafer - A process and apparatus for making die-dried friction wafers collects friction particulates in a mold defining a wafer. The mold includes at least one perforate wall portion against which an aqueous slurry including the particulates is passed to form at least one layer on the wall as the particulates collect in the mold. The collection is dried followed by curing, and may be cured in the mold by heating.01-29-2009
20090056898Highly acoustical, wet-formed substrate - This invention is an acoustic fiber-based substrate composed primarily of insulation-type spun fibers or blends of such fibers and wheel spun fibers. The fibers are bound with a water-dispersible latex binder, or an agri-binder such as starch in conjunction with cellulose fiber. The insulation-type spun fibers can be first quality virgin, post-industrial waste-stream or post-consumer waste stream fiber. The substrate is wet-formed from a very dilute aqueous dispersion of ingredients onto a mesh forming screen, as on a Fourdrinier paper machine. By virtue of the insulation-type spun fiber dimensions, morphology and orientation: very low density wet-mats can be formed from a sufficiently dilute suspension. With respect to other wet-formed substrates, the invention is much lower in density and more highly porous, and, thus, the substrate is highly absorbing, exhibiting noise reduction coefficients, NRC values of about 0.80 or greater. Such NRC values have only been achieved with dry-formed, or air-laid processes in which the fiber are bound with formaldehyde emitting reactive resins.03-05-2009
