  • Patent number: 8399053
    Abstract: A nozzle for dispensing a random pattern of liquid adhesive filaments. The nozzle may include first and second air shim plates, an adhesive shim plate and first and second separating shim plates. The first and second air shim plates each have respective pairs of air slots. Each air slot has a process air inlet and a process air outlet and the air slots of each pair converge toward one another such that the process air inlets are farther apart than the process air outlets in each pair. The adhesive shim plate includes a plurality of liquid slots each with a liquid outlet. Four process air outlets are associated with each of the liquid outlets. The process air slots are adapted to receive pressurized process air and the liquid slots are adapted to receive pressurized liquid adhesive. The pressurized process air discharges from each group of the four process air outlets and forms a zone of turbulence for moving the filament of liquid adhesive discharging from the associated liquid outlet in a random pattern.

  • Publication number: 20130026249
    Abstract: An air spray gun for paint has a tubular body, having an integral screw thread receiving a threaded collar. This secures an air cap against the end of the tube. The air cap has four horns, formed with obliquely inwards directed bores, for patterning the spray, by impinging on it from opposite sides in a manner analogous to that for known air caps having two horns. Behind the air cap in the tube is an air distributor for distributing air to either or both of the pairs of air horns as required to patterning of the paint spray. Paint flow is controlled by a needle withdrawable from a paint nozzle for paint flow. The to needle is in two parts, a front interchangeable part and a rear part connected to the trigger.

  • Patent number: 8347810
    Abstract: A protective member (14) and a nozzle assembly (11) incorporating the protective member (14) are provided. The protective member (14) is for use with a nozzle (12) having a strand guide passageway (18) for receiving a strand (16) of material. Protective member (14) comprises a body (60) configured to be received in the strand guide passageway (18) of the nozzle (12). The body (60) of the protective member (14) has a passageway (63) for the strand (16) and is disposed between the strand guide passageway (18) and the moving strand (16). The body (60) of the protective member (14) is composed, at least in part, of a material having a wear resistance sufficient to resist wear caused by the strand (16) being guided thereby. Alternatively, a portion of the body (60) may be coated with a material having a wear resistance sufficient to resist wear caused by the strand (16).

  • Patent number: 8297530
    Abstract: A spray nozzle assembly that utilizes ultrasonic atomization techniques to atomize a liquid into a cloud of small or fine droplets is disclosed. The nozzle assembly also can use various air or gas atomizing technologies to propel the generally directionless droplet cloud toward a surface or substrate to be coated. The propelled droplet cloud may at this state have a conical or cone-shaped spray pattern. Additional air or gas atomizing technologies can be utilized to shape the propelled droplet cloud into a flattened fan-shaped spray pattern that can be usable in various industrial applications. The shape of the spray pattern and the distribution of droplets within the pattern can be adjusted by manipulation of the gas pressure used in gas atomization.

  • Patent number: 8220725
    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.
