    Abstract: The feeder passages (22) in the aircap (20) of an air spray gun (10) arc slots which are significantly wider than the horn exit holes (24). This construction makes centerline offset much more forgiving by providing a consistent intersection of the passages. The feeder passages (22) are also deeper in that they extent past the intersection point (26) again making them more forgiving of irregularities. Sealing and seating of the nozzle (18) to the fluid inlet (16) have also been improved over the prior art. In the instant invention, o-rings (28) seal the nozzle (18) to the fluid inlet (16) and allow the shoulder (18b) of the nozzle (18) to seat squarely on the spray housing (14) controlling angularity.

    Abstract: The present invention is a spiderweb maker gun comprising a body having a handle, a trigger, and a discharge nozzle. A source of pressurized air is supplied to an air inlet which is secured to the handle of the gun and which is controlled by an adjustable air valve. The discharge side of the air valve has an air conduit extending therefrom which has an air discharge end or nozzle positioned below the glue discharge nozzle so that pressurized air is directed into the stream of hot glue falling or dropping from the glue discharge nozzle. The pressurized air blows the hot glue in a stream towards the area where the spiderweb is to be created with the glue drying and cooling as it is being blown from the gun. The gun is selectively moved while the stream of hot glue is being blown therefrom to create the spiderweb pattern.

    Abstract: The present technique provides a system and method for improving atomization in a spray coating device by internally mixing and breaking up a desired coating fluid prior to atomization. In one embodiment, a flow barrier is disposed in the spray coating device downstream of an internal fluid valve and upstream of a fluid exit. The flow barrier may have a plurality of passages configured to direct fluid streams to create a fluid swirling and rotating motion around a central axis of a central flow path to facilitate fluid mixing and breakup. The plurality of passages may direct the fluid streams toward a surface, and may be angled substantially toward one another or diverging from one another. Embodiments of the spray coating device may further include an atomization mechanism adapted to facilitate formation of a spray of the fluid flowing from the fluid exit. The resulting spray coating has refined characteristics, such as reduced mottling.

A valve ball having primary and secondary flow passages is movable to positions for supplying liquid therethrough to both solid stream and annular fog supply passages, or to only the annular fog supply passage while closing the solid stream passage.

  • Patent number: 6863225
    Abstract: A device and method for applying adhesive to materials, such as elastic strands, used in the production of nonwoven products. Generally, a nozzle is provided and includes a liquid discharge orifice configured to discharge a bead of liquid adhesive. First and second pattern air discharge orifices are associated with the first liquid discharge orifice to vacillate or oscillate the adhesive bead. First and second cleaning and stabilizing air discharge orifices are also associated with the first liquid discharge orifice. These latter air discharge orifices keep airborne contaminants away from the associated liquid discharge orifice and also stabilize the oscillation of the adhesive bead in a single plane. A method in accordance with the invention includes using the nozzle to dispense a vacillating bead of adhesive onto a strand of material.

  • Patent number: 6827299
    Abstract: A liquid spray module which can be individually used, or which can be easily mounted in ganged side-by-side relation with a plurality of such modules. Each module includes a spray gun cartridge having liquid passages through the liquid to be sprayed, is directed and one or more air passages through which pressurized air may be directed for assisting in atomization of the liquid and controlling operating movement of a valve needle. Each spray gun cartridge further includes a manifold body having a central bore into which the spray gun cartridge is removably mounted and liquid and air inlet and outlet passages which communicate with the liquid and air spray gun cartridge passages. The spray gun cartridge is removable from the manifold body without disconnection of fluid supply lines to the manifold body and without removal of the manifold body from a ganged mounted array of such spray modules.

  • Patent number: 6824074
    Abstract: An external mix air atomizing spray nozzle assembly having a nozzle body formed with liquid and air passages, a spray tip at a downstream end of the nozzle body having a nose portion that defines a liquid discharge orifice, and an air cap mounted in surrounding relation to the spray tip nose portion. The air cap defines an annular pressurized air orifice about the spray tip nose portion and a plurality of angled air passages disposed radially outwardly thereof. Pursuant to the invention, the spray tip nose portion has a frustoconical end tapering inwardly in a downstream direction which enhances air entrainment and minimizes liquid turbulence in a zone immediately in front of the air cap and around the spray tip nose portion to prevent undesirable build up of spray material on the exposed end surfaces of the spray tip nose portion and air cap.

    Abstract: Segmental outward projections (12) are provided at radially opposite positions on the circumference of a tubular mount portion (7) of a main body (5), and truncated side portions (13) are provided between and at the opposite sides of the segmental outward projection (12). On the other hand, D-Shaped inward projections (14) are projected radially inward from a boundary portion between fore and rear inner peripheral surface portions (10B) and (10C) of a shaping air ring (10) in such a way as to define an outward projection passageway (15) conforming in shape with the segmental outward projections (12). At the time of mounting the rotary atomizing head (4) on the rotational shaft (3), the outward projections (12) are put in a conforming angular position relative to the outward projection passageway (15) to pass the inward projections (14).

  • Patent number: 6811095
    Abstract: A new and improved hot melt adhesive applicator nozzle assembly comprises an adapter, a dispensing nozzle mounted within the adapter, a nozzle retainer threadedly engaged with the adapter for securing the dispensing nozzle within the adapter, an air inlet ring rotatably mounted upon the nozzle retainer and having an inlet air fitting fixedly mounted therein, and an end cap which is threadedly mounted upon the nozzle retainer. The end cap has swirl air passages integrally incorporated therein, and the end cap and air inlet ring are both fabricated from a suitable thermoplastic polymer material such that all exposed surfaces of the hot melt adhesive applicator nozzle assembly are plastic and are therefore at substantially lower temperature levels than the metal brass components of the hot melt adhesive applicator nozzle assembly.

  • Publication number: 20040169093
    Abstract: A system and method for reducing fluid drainage into air passageways of a spray device during disassembly. The present technique provides an internally mountable fluid nozzle having a fluid inlet, a fluid exit, and a converging central passageway extending substantially between the fluid inlet and the fluid exit. Accordingly, the internally mountable fluid nozzle has a relatively small internal volume, which reduces the amount of fluid that can be spilled during disassembly of the spray device. The present technique also provides a section of the spray device having an air passageway with an air exit, and a protrusive fluid passageway with a fluid exit in a protrusive offset position from the air exit. The internally mountable fluid nozzle can be mounted to the section in fluid communication with the protrusive fluid passageway, such that fluid spillage or drainage during disassembly does not flow into the air passageway.

    Abstract: A system for dispensing liquid material with different configurations of air assisted fiberization or filament movement (e.g., meltblowing, controlled fiberization). In particular, front access for mounting a selected nozzle only requires adjustment of one lever and one fastener. Features of the lever and nozzle allow assisted ejection of the nozzle, even when the nozzle has become adhered to a die body through use. In addition, a nozzle mounting surface of the die body provides a universal interface to the various types of nozzles. An air cavity in the die body and air troughs in selected types of nozzles balance and adjust air flow.
