Operating ConditionsNOTE: Refer to the applicator manual for additional specifications.

Condition Minimum Value Maximum Value Typical ValueAdhesive viscosity 1,000 cps 6,000 cps 1,000-3,000 cpsAdhesive flow per nozzle 5-20 g/min 100 g/min As required

Explanation: Signature nozzles are available in standard and low-flowversions. Minimum and maximum flow are a function of viscosity. Referto Operational Capability later in this manual for additional information.

Pattern air flow per nozzle(see Note A) 0.5 scfm 1.0 scfm 0.6 scfm

Pattern air temperature 0 _C (0 _F) aboveadhesive temperature

14 _C (25 _F) aboveadhesive temperature

0 _C (0 _F) aboveadhesive temperature

Pattern air pressure(see Note B) 0.3 bar (5 psi) 1 bar (15 psi) 0.3-0.6 bar (5-9 psi)NOTE A: Avoid using too much air pressure. Maintaining larger adhesive filaments will improve process stability,

increase bond strength, and reduce air consumption.B: The pattern air flow path is critical. Ensure that the pattern air supply lines are properly sized and that they

are not kinked in a way that restricts air flow.



Operational CapabilitySignature nozzles are available in standard, low-flow, and low-flow,low-density offerings. Standard Signature nozzles:S With a shim thickness of 0.5 mm and orifice diameters equivalent to

0.022 in. (0.56 mm), standard flow Signature nozzles provideadequate performance in the majority of applications and are thedefault nozzle selection.

S With a shim thickness of 0.3 mm and orifice diameters equivalent to0.017 in. (0.43 mm), low-flow Signature nozzles provide additionalhydraulic resistance, improving process stability at low applicationflow rates.

S With a shim thickness of 0.3 mm, six adhesive orifices (standard andlow-flow nozzles have 12 orifices), and orifice diameters equivalent to0.017 in. (0.43 mm), 25-mm low-flow, low-density Signature nozzlesare recommended for applications in which very low productionspeeds and/or low material add-on conditions exist.

Most production environments require a range of flow rates at a fixedmaterial viscosity. Application requirements will determine the selection ofstandard, low-flow, or low-flow, low-density nozzles. To aid in nozzleselection, the Signature nozzle capabilities are shown graphically in Figures4 through 6.

TroubleshootingProblem Possible Cause Corrective Action Example

1. Good pattern (forreference only)

Not applicable Not applicable

2. Pattern breakingup with resultingcontamination ofmachine

Adhesive temperature toohigh; viscosity too low(resulting in brokenadhesive filaments)

Verify that viscositycorresponding toapplication temperature isin adherence to thepublished best practices.

Pattern air flow/pressuretoo high for given flow rate

Reduce the pattern airflow/pressure.

3. Buildup ofadhesive at nozzletip(s)

Adhesive temperature toolow (resulting in poorprocessibility)

Increase the adhesivetemperature and ensureadherence to thepublished best practices.

4. Low bond strength Adhesive temperature toolow to provide adequategrip

Increase the adhesivetemperature.

Distance from adhesiveapplication to nip point toolong

Decrease the distancefrom the point of adhesiveapplication to thecombining point (seeFigure 1) and theapplication of nip pressure.

Pattern air flow/pressuretoo high, resulting inexcessive adhesivefilament attenuation andsmall fiber diameters

Reduce the pattern airflow/pressure to achievelarger adhesive filaments.

Check the nozzle fordamage and clean orreplace if needed. Removethe module and check forblockage in the pattern airpath.

6. Pattern drop in andout, resulting ingaps and erraticoperation

Nozzle back pressureinadequate for stableoperation (low-flowcondition)

Refer to the operatingwindow graphics todetermine if a low-flowcondition exists for thegiven adhesive viscosity.Use low-flow nozzles.Low-flow nozzles increasethe resistance to flow andimprove process stability.Decrease the adhesivetemperature slightly toincrease viscosity andresistance to flow.

7. Ends of patternspull inward,resulting in gapsbetween adjacentnozzles oradhesive filamentscombining(causing heavyand light areas inpattern)

Adhesive temperature toolow or pattern air flow toolow for given adhesive flow

Verify that viscositycorresponding toapplication temperature isin adherence to thepublished best practices.Adjust the pattern airflow/pressure.

8. Outermost ends ofpatterns pullinward, resulting innarrowed overallpattern width

Air currents created byhigh speed movement ofconverting machinery areaffecting the strands

Verify that viscositycorresponding toapplication temperature isin adherence to thepublished best practices.Adjust the pattern airflow/pressure.



Nozzle ServiceRemoving or Installing a Nozzle

You will need the following items:S Appropriate tools, including a torque wrenchS Drain pans and disposable ragsS O-ring lubricant (for lubricating nozzle O-rings)

WARNING! System pressurized! Relieve system hydraulic pressure beforebreaking any hydraulic connection or seal. Failure to relieve the systemhydraulic pressure can result in the uncontrolled release of hot melt or coldadhesive, causing personal injury.

WARNING! Molten material! Wear eye or face protection, clothing thatprotects exposed skin, and heat-protective gloves when servicing equipmentthat contains molten hot melt. Even when solidified, hot melt can still causeburns. Failure to wear appropriate personal protective equipment can resultin personal injury.

Remove a Nozzle1. Heat the system to application temperature.2. Relieve system pressure. Refer to the applicator manual as needed.3. Trigger the applicator solenoid valves to relieve any remaining pressure.4. Shut off the module-actuating air.5. Decrease the pattern air pressure. Leave just enough air pressure to

prevent adhesive from entering the pattern air outlet on the module.See Figure 7.6. Back the nozzle-retaining clamp screw all the way out until it stops (1).7. Push up (2) on the nozzle-retaining clamp screw to eject the nozzle.

Install a NozzleSee Figure 7.1. Clean (3) the mating surface where the nozzle will be seated.2. Inspect the nozzle seal, replace if necessary, and ensure that the seal is

lubricated and properly positioned in the seal bore.3. Carefully angle and insert the nozzle in the module seat (4, 5).

CAUTION! Overtightening a nozzle-retaining clamp screw can damage themodule.

Cleaning NozzlesYou will need the following items:S Appropriate toolsS Cleaning supplies (refer to Tables1 and 2)S Drain pans and disposable ragsS O-ring lubricant (for lubricating nozzle seals)

1. Remove the nozzles. Refer to Remove a Nozzle earlier in this section.2. Disassemble (refer to Parts) and clean the nozzles using one of the

Nordson-recommended methods shown in Tables 1 and 2. Use onlycleaning agents recommended by the adhesive supplier.

WARNING! System pressurized! Relieve system hydraulic pressure beforebreaking any hydraulic connection or seal. Failure to relieve the systemhydraulic pressure can result in the uncontrolled release of hot melt or coldadhesive, causing personal injury.

WARNING! Molten material! Wear eye or face protection, clothing thatprotects exposed skin, and heat-protective gloves when servicing equipmentthat contains molten hot melt. Even when solidified, hot melt can still causeburns. Failure to wear appropriate personal protective equipment can resultin personal injury.

WARNING! Risk of explosion or fire. Follow the safety guidance and heatingrecommendations on the Material Safety Data Sheets (MSDSs) for youradhesives and nozzle-cleaning solutions.

WARNING! Risk of explosion or fire. Use a controlled heating device, suchas a thermostatically controlled hot plate, to heat cleaning fluid, includingNordson Type-R fluid.

CAUTION! Risk of equipment damage. Do not use a wire brush (or a brushwith bristles harder than the nozzle) to clean nozzles.



Table 1 Preferred Nozzle Cleaning MethodCleaning Method Procedure

Oven (preferred) WARNING: Risk of explosion, fire, or toxic vapor release.Depending on the type of adhesive and/or organic solvent usedwith the nozzles, heating them in an oven can cause a hazardousevent. Before using an oven to clean nozzles, consult with theoven manufacturer about the viability of this method and thesafety risks. Follow the manufacturer's recommendations.WARNING: Use the oven heating controls to keep the oven at thedesired temperature. Do not use an oven that does not haveheating controls.

CAUTION: Risk of equipment damage. Remove seals beforecleaning nozzles in an oven. Failure to do so can cause a chemicalreaction that will permanently damage the nozzles.

a. Ensuring that seals have been removed from the nozzles, place them inan electric oven heated to approximately 385 _C (725 _F). Allow thenozzles to bake for approximately 3-4 hours.

WARNING: The heating temperature and time may need to beadjusted based on the oven type, the adhesive type, and theamount of char buildup on the nozzles. Nordson Corporationrecommends testing this procedure on discarded nozzles prior tousing it on good nozzles.

WARNING: Risk of fire. Use a heat-proof cloth to clean nozzles. Evencotton can burn in high-temperature conditions.

WARNING: Risk of equipment damage. Handle nozzles carefully toavoid denting the orifices, which can degrade the adhesive pattern.

b. Turn off the oven and allow the nozzles to cool; then remove thenozzles.

c. Wipe the nozzles with a soft cloth and then gently blow air through thenozzle orifices from the mounting side of the nozzle.



Cleaning Nozzles (contd)

Table 2 Other Nozzle Cleaning MethodsCleaning Method Procedure

Citrus-based solutionand ultrasonic tankNOTE: This is the mostthorough method.

a. Place the nozzles in citrus-based solvent/degreasing solution and soakthem overnight or for approximately 4 hours. This dissolves and loosens theadhesive and char buildup.

b. Remove the nozzles from the citrus-based solvent/degreasing solution andplace them in an alkaline solution heated to the appropriate temperature(refer to the MSDS) in an ultrasonic tank. Soak the nozzles forapproximately 10 minutes. This will remove adhesive and char from theorifices.

c. Scrub the nozzles with a soft, non-metallic brush to remove debris.d. Gently blow air through the nozzle orifices from the mounting side of the

nozzle.Nordson Type-R fluid a. Place the nozzles in a controlled heating device containing Nordson Type-R

fluid and heat it above the melting point of the adhesive (refer to the MSDS).b. Scrub the nozzles with a soft, non-metallic brush to remove debris.

Electric heat gun a. Heat the nozzles with a flameless electric heat gun.b. Scrub the nozzles with a soft, non-metallic brush to remove debris.

Ultrasonic tank a. Place the nozzles in an alkaline solution heated to the appropriatetemperature (refer to the MSDS) in an ultrasonic tank. Soak the nozzles forapproximately 10 minutes.

b. Scrub the nozzles with a soft, non-metallic brush to remove debris.c. Gently blow air through the nozzle orifices from the mounting side of the

nozzle.

3. If there is any remaining char buildup on the nozzles, gently scrape thechar from the nozzles.

4. Reinstall the nozzles. Refer to Install a Nozzle earlier in this section.5. Restore the system to normal operation.
