Abstract:
An application system for applying a solid particle includes an injector housing having a material inlet, a gas inlet, and a material outlet, and an occluder moveably disposed within the injector housing between the gas inlet and the material outlet. The injector housing and the occluder define there between at least one adjustable aperture downstream of the material inlet and in fluid communication with the gas inlet and the material outlet. The aperture has a first open area with the occluder in a first position and a second open area with the occluder in a second position, the second open area being different than the first open area. The system also includes a nozzle having a nozzle inlet coupled to the material outlet and a nozzle outlet, the inlet having a circular cross-section and the outlet having a rectangular cross-section.
Abstract:
A machine for conditioning and dispensing loose fill insulation material, such as cellulosic insulation, fiber glass insulation and rock wool insulation. The machine includes a hopper, a conditioning chamber, an air lock and a blower for pneumatically dispensing the material. The conditioning chamber is equipped with three rotating shafts with helically arranged spikes which serve as conveyors as well as dispersers. A lower conveyor shaft moves the material toward the opening into the air lock, while the two uppermost conveyor shafts move the material in the opposite direction. Thus, the same assembly which conveys the material to the air lock also conditions the material. Moreover, the counter current flow pattern churns or agitates the insulation material while the individual spikes disperse it. A single motor drives the rotation of the conveyor shafts and the rotation of the vanes in the air lock.
Abstract:
A fiber spray system for depositing fibers onto a substrate or article comprises a vibrating feeder bowl having an opening in its sidewall covered by a grid or screen through which fibers loaded into the feeder bowl are discharged therefrom into the fiber collector. A delivery hose is connected between the fiber collector and a pump which is operative to create a negative pressure within the fiber collector to draw fibers through the grid of the feeder bowl, out of the feeder bowl into the fiber collector and to entrain the collected fibers within a stream of air. The air-entrained fibers are drawn through the delivery hose to the pump, and in the course of passage therethrough the velocity of the fibers is reduced so that they collect or accumulate within an area in the delivery hose upstream from the pump. The pump uniformly withdraws fibers from the area where they accumulate and discharges the fibers directly into a spray gun connected to the pump for deposition onto a substrate.
Abstract:
A portable apparatus for blowing a chemically treated cellulose insulating material into an attic, wall cavity or wet spraying the material against a surface for insulating it. The apparatus breaks the cellulose material into small particles and, after fluffing the material, the apparatus meters and feeds the material under pressure through a hose and out through a nozzle where an operator can point the nozzle for directing the material to any desired area. Three different nozzles are used: one for attic insulation; a second for filling wall cavities; and a third for wet spraying the material against a surface for causing the material to adhere to the surface.
Abstract:
A particle sprayer includes a source of discrete particles, a spray outlet coupled to the particle source, and a conduit extending from a pressurized fluid inlet to the spray outlet and configured to constrain a flow of carrier fluid to flow along the conduit toward the spray outlet to propel particles from the particle source away from the spray outlet. The particles including discrete fastening bits having one or more projections, with each projection having an overhanging head for snagging fibers. The particle sprayer may be used to spray fastening bits onto a surface, to turn the surface into a touch fastener.
Abstract:
Provided are methods and techniques for a spraying fibers. A container having an agitator or a blade assembly in its bottom section is obtained and then partially filled with fibers, so as to at least partially cover the agitator or blade assembly. The agitator or blade assembly is operated with the container substantially closed, thereby causing a plurality of the fibers to become airborne within the container, and then an airflow is created to draw the airborne fibers out of the container. Finally, the airborne fibers that have been drawn out of the container are directed into a desired spray, using a sprayer.
Abstract:
In an apparatus including a shooting device, a planting device, a drive source for feeding pressurized air to the shooting device, a pile feeding container in communication with the shooting device, and a charge supply including positive and negative charge supply terminals, a method for three-dimensionally planting pile includes coating adhesive on one or more surfaces of a three-dimensional member; electrically connecting the positive charge supply terminal to the planting device for forming a positive electric field thereon; electrically connecting the negative charge supply terminal to the member to be planted for forming a negative electric field thereon with an electrostatic field from the planting device to the member being established; activating the shooting device to project pile through the planting device toward the one or more surfaces of the member as driven by the electrostatic field; and adhering the pile to the one or more surfaces of the member.
Abstract:
A loose-fill blowing machine is provided having an input for receiving loose-fill insulation for blowing. The blowing machine includes at lest one magnet disposed proximate to the input for attracting magnetic materials received in the input.
Abstract:
Apparatus for feeding flock fibers comprising an upwardly open flock-receiving hopper. The hopper has a bottom discharge passage under which is mounted metering apparatus providing a plurality of discharge openings of controllably variable size. An upper impeller having a plurality of downwardly angled blades is rotatably driven within the hopper passage to urge the flock fibers to fall downwardly through the discharge openings into a cylindrical pump chamber. A lower impeller is rotatably driven within the pump chamber to sweep falling flock fibers into a pump throat in communication with a venturi flow tube through which a supply of air is passed. The air flowing through the venturi flow tube creates suction to draw the fibers within the throat into the venturi flow tube for entrainment with the air stream.
