Abstract: A method of applying blend drop granules to an asphalt coated sheet includes moving an asphalt coated sheet in a machine direction, depositing a blend drop of granules on a blend drop conveyor that is moving at a first speed, changing the speed of the blend drop conveyor to a second speed that is closer to the speed of the moving asphalt coated sheet than is the first speed, and releasing the blend drop from the blend drop conveyor for contact with the asphalt coated sheet.

Abstract: A method of applying blend drop granules to an asphalt coated sheet includes moving an asphalt coated sheet in a machine direction, and depositing blend drops of granules on a blend drop conveyor that is positioned above the asphalt coated sheet. The blend drop conveyor has an upper flight moving in a direction opposite the machine direction and a lower flight moving in the machine direction. The blend drops are moved from the upper flight to the lower flight of the blend drop conveyor while retaining the blend drops in contact with the blend drop conveyor by magnetic force. Finally. The blend drops are released from the blend drop conveyor for contact with the asphalt coated sheet.

Abstract: A method of applying blend drop granules to an asphalt coated sheet includes moving an asphalt coated sheet in a machine direction, generating vertically moving blend drops of granules and directing the vertically moving blend drops of granules into contact with a curved conveyor. The blend drops are moved along the curved conveyor to change the direction of the blend drops of granules to a generally horizontal orientation in the machine direction. The blend drops are released from the curved conveyor for contact with the asphalt coated sheet.

Abstract: A method and device is disclosed for distributing a veil by applying low frequency sound to at least one portion of the veil, and causing the veil to deviate in its generally downward direction of travel. In its simplest embodiment, the lapping device of the present invention includes one low frequency sound generator having one resonator tube shaped for emission of low frequency sound and having an open end from which sound may be emitted to a portion of a veil. Preferably, the lapping device has two resonator tubes whose open ends are in spaced, opposing relationship, and in the preferred method low frequency sound is alternately applied at generally opposing locations near the veil, causing portions of the veil to deviate in generally alternate directions in its direction of travel.

Abstract: A loose-fill insulation product having irregularly shaped glass fibers is provided. The loose-fill insulation product shows improved recovery, lower thermal conductivity and requires lower product densities than prior art loose-fill insulation at equivalent fiber diameters.

Abstract: A glass fiber insulation product includes irregularly-shaped glass fibers of two different glasses having differing coefficients of thermal expansion, with the irregularly-shaped dual-glass fibers exhibiting a substantially uniform volume filling nature, and providing improved recovery and thermal conductivity abilities even in the absence of a binder material.

Abstract: A loose-fill insulation product is provided which may be poured or blown by a consumer. The insulation is comprised of irregularly-shaped glass fibers which are comprised of two distinct glass compositions. The loose-fill insulation product may be densely packaged in a small container for consumer use, and shows improved recovery, good thermal efficiency, and low dust upon blowing or pouring.

Abstract: Methods, apparatuses, and devices are disclosed for collecting a veil including long fibers with high speed conveyor surfaces to produce a web of loosely related fibers, and further forming a wool pack by distributing the web of fibers with low frequency sound. The methods, apparatuses, and devices are particularly useful in collecting long fibers, and producing wool packs including long glass fibers.

Abstract: A loose-fill insulation product is provided which is formed from a blend of first and second insulating materials having three-dimensional groups of fibers of different sizes and densities. At least one of the insulating materials is comprised of irregularly-shaped glass fibers comprised of two distinct glass compositions. When blended with the fibers of a standard insulation or with other irregularly-shaped fibers of different sizes, the resulting loose-fill insulation product shows improved coverage and thermal efficiency.

Abstract: A method and apparatus for distributing fibrous includes establishing a flow of fibrous material, positioning at least one flow distributor in a position to direct at least one gaseous flow into contact with the flow of fibrous material to distribute the fibrous material, and directing an intermittent flow of gas from the distributor, where the flow of gas increases and decreases linearly during the flow cycles.

Abstract: A method and apparatus for distributing fibrous material includes establishing a flow of fibrous material, positioning at least two flow distributors in a position to direct a gaseous flow into contact with the flow of fibrous material, such as a flow of glass fibers, each flow distributor having an outer surface having one or more openings for the emission of gas, an inner surface having one or more orifices for the emission of gas, and a pressurized source of gas in contact with the inner surface, the inner surface being moveable with respect to the outer surface to intermittently align some of the openings with some of the orifices, thereby enabling gas from the pressurized source of gas to be emitted through the inner and outer surfaces and into contact with the flow of fibrous material to distribute the fibrous material, and moving one of the surfaces relative to the other of the surfaces to control the emission of gas from the flow distributor.

Abstract: An improved fibrous glass insulation assembly (10) having a fibrous glass body (12), a moisture barrier (14) that substantially encloses the fibrous glass body (12), and a desiccant (18) positioned adjacent the fibrous glass body (12) and within the moisture barrier (14). The fibrous glass body (12) is sufficiently encapsulated or enclosed by the moisture barrier (14), the moisture barrier (14) sufficiently retards the passage of moisture therethrough, and the desiccant (18) is disposed in a sufficient quantity so that enough moisture is removed to improve the recovery performance of the fibrous glass body (12), from a recoverable compressed state, and/or to improve the stiffness performance of the fibrous glass body (12), once the glass body (12) has recovered.
