Abstract:
A hot melt adhesive system includes a supply container for storing adhesive particulate, a transfer pump operatively connected to the supply container, a transfer hose operatively coupled to the transfer pump, and a blocking member. The blocking member is movable between a first position in which stored adhesive particulate and air are permitted to be withdrawn from the supply container into the transfer hose, and a second position in which the stored adhesive particulate is blocked from passing through the transfer hose while air is permitted to pass therethrough to flush the transfer hose of residual adhesive particulate.
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.

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:
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:
A spray deposition apparatus comprises a source of aqueous fiber slurry that includes a mixture of milled graphite fibers in suspension. A slurry input 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 receives pressurized gas. A nozzle aspirates the mixture of aqueous fiber slurry with the pressurized gas to produce a stream of fiber cluster droplets.
Abstract:
A system and corresponding method blow or spray loose-fill insulation (e.g., fiberglass) into wall cavities and the like. The system includes 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 loose-fill insulation product is provided which includes a dry mixture of loose-fill fiberglass and an inorganic (being composed of matter other than plant or animal) 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. According to certain embodiments, this mixture may be blown into open attic areas so as to insulate same and reduce the movement of loose-fill insulation.
Abstract:
A method and apparatus for controllably delivering discrete loose fill dunnage particles from a supply to a packaging site and for applying an additive to at least a portion of an exposed surface on a plurality of particles to cause abutting particles to adhere to each other. The apparatus consists of: a conduit having an inside wall surface defining a conveying path for loose fill particles, an inlet end communicating with the loose fill particle supply, and an outlet end for discharging loose fill particles conveyed from the supply through the conduit to the packaging site; a nozzle for producing a shower of additive through which a plurality of loose fill particles conveying between the supply and the packaging site pass; and structure for delivering a pressurized additive through the nozzle so that the additive is directed by the nozzle in a pattern adjacent to the outlet end of the conduit.
Abstract:
A fully integrated insulation spraying system with an insulation spraying subsystem for spraying wet or dry insulation and a fiber recovery subsystem for recycling waste insulation fibers and reintegrating them into the spraying process for more efficient and ecologically sound use of the insulation material. The insulation spraying subsystem includes a hopper with a rotary conveyor that conditions the fiber insulation and carries it into a standby chamber which is connected an airlock that introduces the fibers into a moving airstream. The airstream carries the fibers to the spraying head where moisture is added to promote adhesion of the insulation. A pneumatically powered insulation shaver is provided for smoothing the insulation after it is applied. The fiber recovery subsystem includes a vacuum powered pickup for gathering the waste insulation that is shaved off, a cyclone separator and primary and secondary filters for collecting the fibers, and an airlock for metering the fibers into the airstream of the insulation sprayer. Preferably, the system is mounted on a truck for transportation to a construction site. A self-contained power unit, which operates the air pumps, water pump and mechanical components of the system, further increases the portability and efficiency of the system.
