Normally, the choice of nozzle for your applicator will have already beenmade by you and your Nordson representative. Refer to your sales orderto determine what nozzle choices were made. The part numbers for themost commonly used nozzles are provided here.

NOTE: Some nozzles require the use of an adapter. Refer to AdapterPart Numbers earlier in this section for adapter part numbers.

CF Nozzles

There are three types of CF nozzle, as shown in Table 9-4. CF nozzlesmay have either 6 air openings or 12 air openings. Nozzles with 12 airopenings are referred to as high-frequency nozzles. To use a CF nozzlewith a Universal module, an adapter is required. Refer to Adapter PartNumbers earlier in this section for the CF adapter part number.Figure 9-13 shows a typical CF nozzle.

Table 9-4 Types of CF Nozzles

CF Nozzle Type Description

Disk The nozzle disk and the nozzle-retaining nut aretwo separate parts. The disk is held onto themodule by the nozzle-retaining nut and isprotected from damage because it is recessedinside the nut.

Unibody The nozzle disk and the nozzle-retaining nut area single assembly. This design makes thenozzles easier to clean because there are norecessed surfaces (as on disk nozzles).However, the nozzle disks may be moresusceptible to damage. The nozzle-retaining nutson unibody nozzles are color-coded for ease ofidentification.

Steel unibody Steel unibody nozzles are exactly like unibodynozzles except that they are more durable.

Meltblown Nozzles

Meltblown nozzles may be full coverage or partial coverage nozzles.They may also be high or low-density (high-density nozzles apply aheavier, denser coating than low-density nozzles):

� See Figure 9-14. A full coverage, high-density nozzle has24 openings that extend along the entire length of the nozzle. Afull-coverage, low-density nozzle has 12 openings that extendalong the entire length of the nozzle. The adhesive coating widthin either case is 25 mm.

� A partial coverage high- or low-density nozzle has openingsthrough only part of the nozzle, leaving a closed area at either oneor both ends. A partial coverage nozzle may be oriented to applyadhesive starting at the left, right, or center of the nozzle. Variousnozzle widths are available in either side-oriented orcenter-oriented configurations. Note that the nozzles aresymmetrical, which means that a partial coverage nozzle can bepositioned for either right-side or left-side coverage.

No adapter is required to use a meltblown nozzle on a Universal module.
