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:
A honeycomb filter production apparatus includes: a workpiece securing section for securing a base of a honeycomb filter; a powder transfer section for transferring a powder together with an air current by utilizing pressurized gas; an introduction section for introducing the powder that has transferred from the powder transfer section into the base secured by the workpiece securing section when the apparatus is used; a suction section for sucking the gas that has passed through the base secured by the workpiece securing section using suction means; a cleaning section for removing a surplus powder adhering to an end face of the base after the introduction of the powder; a judgment section for judging an amount of the powder adhering to the base; and a workpiece transfer section for transferring the base among the workpiece securing section, the cleaning section, and the judgment section.
Abstract:
A system for transporting insulation particles suitable for use in a process for forming an insulation product is provided, comprising: a blowing machine for forming an insulation particle/air suspension, wherein the blowing machine comprises at least one opening, and a hose in communication with the at least one opening, for transporting the suspension to or from the blowing machine, wherein the internal diameter variation of at least a portion of the hose is less than about 0.20 inch.
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 system and corresponding method are disclosed for blowing or spraying loose-fill insulation (e.g. fiberglass) into wall cavities and the like the system including a fiber recovery or recycling subsystem that vacuums up overspray or waste fibers and forwards them back toward the hopper. A fiber collector device having a fiber inlet and outlet is mounted above the hopper, and receives the recovered waste fibers and redistributes them back into the hopper so that they mix with virgin fibers therein. The mix of recovered and virgin fibers is then blown through the blow hose toward a wall cavity or the like to be insulated.
Abstract:
A system for recovering waste fiber and reusing it with a loose-fill blown-in-place insulation system includes a fiber collector device mounted above the feed hopper, which collector receives the waste (i.e. recovered) insulation for recycling into the blowing operation. The collector includes a unique set of angled baffles which serve to thoroughly redistribute the recovered waste fibers back into the feed hopper for more even and uniform mixing with the new, virgin fibers being added. To accomplish this distribution the baffles are located so as to increase in surface area as a function of increased distance from the inlet.
Abstract:
A loose-fill insulation product is provided which includes a dry mixture of loose-fill fiberglass and an inorganic adhesive in the form of a redispersible powder. During application, the dry loose-fill mixture is coated with a liquid (e.g. water) so as to activate the adhesive. Thereafter, the loose-fill mixture with activated adhesive is blown or sprayed into a cavity (open or closed) so as to insulate same.
Abstract:
Fibrous web structures in which the individual fibers are uniformly felted in random orientation are produced by projecting a stream of solids suspended in air toward a moving porous collection surface. The fibers are maintained in a controlled condition uniformly dispersed in air during transit from the nozzle to the porous collecting surface and before the stream of air has spread to the point of disrupting the uniform fiber dispersion, the fibers are felted and collected on the porous support while air is continuously passed through the support to insure no gravity free fall of fibers. Liquid or dry adhesive binders may be incorporated into the structure at any convenient stage of the process but preferably before the web structure is formed on the moving support.
