    摘要: An insulated air duct includes a flexible, reinforced, inner tubular core; a layer of partially compressed flexible, resilient fibrous insulation surrounding the core; and a flexible jacket, preferably with a longitudinally extending seam, spaced outwardly from the core and enveloping the layer of partially compressed fibrous insulation. The layer of partially compressed fibrous insulation is formed from a resilient blanket of air laid, randomly oriented, entangled fibers. The resilient blanket may have a low binder content or be binderless with the fibers unbonded and, possibly, lubricated. The lubricant on the fibers facilitates the sliding of the fibers relative to each other, reduces fiber attrition due to abrasion as the fibers move relative to each other; and enhances the resilience of the blanket when subjected to compression whereby the layer of compressed fibrous insulation surrounding the core remains expanded in its partially compressed state, to the extent permitted by a space between the core and the jacket, to provide the duct with good insulating properties and to exert an outward pressure on the jacket to improve the appearance of the jacket. Preferably, the resilient blanket is wrapped about the core while being supported on the jacket so that the blanket will not pull apart during the wrapping process.

    摘要: A multi-component fiberizing disk for fiberizing a molten fiberizable material in a rotary fiberization process includes: an annular sidewall having fiberizing holes therein through which a molten fiberizable material passes to fiberize the molten fiberizable material; an upper annular flange; and a base having an annular outer peripheral edge. The annular sidewall, the upper annular flange and the base are made from at least two separate components and, preferably, from three separate components. The separate components are secured to together as the fiberizing disk by fasteners, such as bolt and nut fasteners, that permits the separate components of the fiberizing disk to be disassembled after service. The different components can be made of different metal alloys and a distribution manifold can be incorporated into the fiberizing disk for distributing the molten fiberizable material(s) within the fiberizing disk and to make bi-component fibers.

    摘要: In an apparatus and method of forming fibers from a fiberizable material, a molten fiberizable material is introduced into a rotating fiberizing rotor and passed through a plurality of holes in an annular peripheral sidewall of the fiberizing rotor to form primary fibers from the fiberizable material. The primary fibers are introduced into hot combustion gases and pressurized air in a fiberization zone adjacent an outer surface of the annular peripheral sidewall of the rotary fiberizing rotor to attenuate and form the primary fibers into fibers of the desired diameter and length. The hot combustion gases are discharged from an annular air cooled burner and the pressurized air, which is discharged form an annular air ring, is the same pressurizes air used to cool the annular air cooled burner.
