Abstract:
The present invention solves the problem of controlling the amount of particles of fibres which are emitted in a nozzle from a gas flow when these are transported by the gas flow through a flexible hose or some other canal from a container. Due to the fact that the amount of fibres or other particles which are emitted can be controlled in a simple way, an accurate control of the density of a layer which is applied can be made, an even layer can be achieved and unnecessary material consumption can be avoided. The problem is solved primarily in that a gas flow containing the particles is conducted in a canal to a valve arranged where the particles are to be emitted, a second canal leads from the valve to a suction source and the vent comprises regulating means for controlling the size of the gas flows to the suction source and to the outlet of the valve. By means of this construction a continuous flow of fibres or particles can be guided towards the valve and that part which is not emitted to the nozzle is conveyed further by the suction source and is collected. By means of the above-mentioned method an application of fibres or particles in an adhesive layer, applied with, for example, melt adhesives or cold adhesives, may be guided during a course which can be continuous or intermittent.
Abstract:
A particle sprayer includes a particle source, a particle distribution system in hydraulic communication with the particle source, and a spray outlet coupled to the particle distribution system for spraying particles from the particle source, where the particles include discrete fastening bits having one or more projections, with each projection having an overhanging head for snagging fibers. The particle distribution system includes at least one of 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, and a valve in hydraulic communication with the particle source for dispensing particles from the particle source. The particle sprayer may be used to spray fastening bits onto a surface, to turn the surface into a touch fastener.
Abstract:
A spray deposition apparatus comprises a source of aqueous fiber slurry (104) that includes a mixture of milled graphite fibers in suspension. A slurry input (102) of the spray deposition apparatus is coupled to the source of aqueous fiber slurry. The slurry input receives the mixture of aqueous fiber slurry. A gas pressure input (106) receives pressurized gas. A nozzle (110) aspirates the mixture of aqueous fiber slurry with the pressurized gas to produce a stream of fiber cluster droplets (112).
Abstract:
Nozzles for converting clumps and nodules of dry or substantially dry fibrous insulation to pils and for spraying on the so treated and accelerated air entrained insulation pieces to form thermal and acoustical insulation in building cavities. The nozzles comprise a shredder section for reducing the size of many of the pieces of insulation to pil size and an accelerator section for increasing the velocity of a stream of air suspended pils for improved just-installed insulation integrity or strength. The shredder and the accelerator can also be combined in a single unit.
Abstract:
A method and apparatus for simultaneously insulating cavity portions and securing batt insulation in the cavity to be insulated. The present invention provides a system for using a mixture of insulating material, a dissipating foam, and an adhesive to hold the batt insulation in a frame that defines a cavity to be insulated. In one embodiment the mixture is applied only to the border of the cavity (6). In another embodiment the insulating material comprises fly ash particles.
