Description of Components / Functioning

Material Flow

The melter pumps the material through a heated hose to the applicator. In theapplicator the material flows through the filter cartridge(s) and the materialchannels to the nozzle. Control modules open and close the material supplyto the nozzle. The nozzle applies the material to the substrate in a contactcoating process.

The application pattern is determined by grooves in the mouthpiece or by ashim plate. The shim plate is located between the nozzle mouthpiece and themouthpiece receptacle. The application pattern also depends on the speedat which the substrate moves, the quantity of material and the materialtemperature.

In addition, the quality of the application is influenced by the distance and theangle between the nozzle and the substrate.

Nozzle

The applicator nozzle touches the substrate, causing it to naturally wear. Itmay need to be refaced. Refer to page 33.

Control Modules

The control modules open and close the material supply to the nozzle byraising or lowering the nozzle stem. A compression spring ensures that thecontrol module outlet is closed when control air pressure drops, preventingmaterial from being applied.

The number of control modules is a factor of the greatest application widthpossible.

Heating

The applicator is heated with electrical heater cartridges. The temperature iscontinuously measured by temperature sensors and is controlled withelectronic temperature controllers. Temperature controllers are not part ofthe applicator.

Filter Cartridge

The material flows from the inside of the filter cartridge to the outside. Thusdirt particles remain in the filter cartridge.

Applicator 15


InstallationATTENTION: Allow only qualified personnel to perform the following tasks.Observe and follow the safety instructions in this document and all otherrelated documentation.

UnpackingUnpack carefully. Then check for damage caused during transport. Reusepackaging materials or dispose of properly according to local regulations.

Transport and StorageNOTE: The applicator is a high precision, valuable part. Handle verycarefully!

CAUTION: Do not store outside! Protect from humidity and dust. Protect thenozzle from damage. Do not lay unit on the nozzle.

Removing Shim Plate BlankThe applicator includes a shim plate blank. It is in the nozzle during transportand must be removed before initial startup of the applicator.

1. Disassemble nozzle (Refer to page 31).

NOTE: Before initial startup, the applicator need not be heated todisassemble the nozzle.

2. Remove the blank and save it for later use.

Installing

� Protect from humidity, vibrations, dust and drafts.

� Ensure access to parts relevant for maintenance and operation.

� To achieve optimum material application, install the applicator in theparent machine such that the distance and, when appropriate, the anglebetween the nozzle and the substrate can be varied.

� The applicator bracket must allow for heat expansion.

� Cables, air hoses and heated hoses may not be bent, pinched, torn off orotherwise damaged.

Exhausting Material Vapors

Ensure that material vapors do not exceed the prescribed limits. Exhaustmaterial fumes when necessary. Provide sufficient ventilation of the locationwhere the unit is installed.

ATTENTION: It is imperative that the following additional safety regulationsare followed when processing polyurethane hot melt adhesives (PUR) (Referto General Hot Melt Material Processing Instructions).

Electrical ConnectionATTENTION: Risk of electrical shock. Failure to observe may result inpersonal injury, death, or equipment damage.

Laying Cable

ATTENTION: Do not pinch cables and check regularly for damage. Replacedamaged cables immediately!

Connecting Heater

Insert the voltage plug into the corresponding receptacle on the melter orterminal box. If the heater lines are integrated into the material hose, thecorresponding receptacle is located directly on the material hose. Secure thevoltage plug with the clamp if necessary.

Connecting Solenoid Valves

The solenoid valves on the control modules are controlled either by anexternal power supply, e.g. control unit, or through the valve control lines ofthe heated hose. Secure the plug connection with the screw (1, Fig. 3).

Fig. 3

Applicator 17


Pneumatic ConnectionsNordson recommends using dry, controlled and nonlubricated compressedair.

Operation with Nonlubricated Compressed Air

When an applicator is connected to a compressed air system in which thecompressed air has previously been lubricated, simply ceasing to lubricatethe air is not sufficient. The oil remaining in the compressed air supply willreach the solenoid valves and the control modules and wash out the originallubricant/oil from these parts, substantially decreasing the service life of theunits.

NOTE: It must be ensured that the compressed air supply to the applicatorshas been converted to absolutely nonlubricated operation.

NOTE: No oil from a possibly defective compressor may be permitted topenetrate the compressed air supply.

NOTE: Nordson will assume no warranty or liability for damage caused byunpermitted, temporary lubrication.

Conditioning Compressed Air

The quality of the compressed air must be at least class 2 as stipulated byISO 8573-1. This means:

� Max. particle size 1 �m

� Max. particle density 1 mg/m3

� Max. pressure dewpoint -40 °C

� Max. oil concentration 0.1 mg/m3.

Connecting Compressed Air

1. Connect customer's air supply to the inlet of an air conditioning unit.

Maximum air pressure:

10 bar 1 MPa 145 psi

2. Connect the control modules to the air conditioning unit.

3. Set control air pressure:

Approx. 5 to 6 bar Approx. 0.5 to 0.6 MPa Approx. 72.5 to 87 psi

Connecting Heated Hose

ATTENTION: Hot! Risk of burns. Wear heat-protective gloves.

CAUTION: When the applicator has only one filter cartridge, connect theheated hose to the side of the body where the filter cartridge is located.

If the hose connection is moved from one side to the other, the filter cartridgemust also be moved to the other side. Refer to next page.

Connecting

If cold material can be found in the hose connection (1, 2), these componentsmust be heated until the material softens (approx. 80 °C / 176°F).

1. First connect the hose (3) electrically.

2. Heat the unit and hose until the material softens (approx. 80 °C / 176 °F).

3. Screw on heated hose.

CAUTION: Always connect the hose to the side of the body where the filtercartridge is. This is the only way to ensure that the material is filtered.

Disconnecting

Relieving Pressure

ATTENTION: System and material pressurized. Before removing heatedhoses and applicators, relieve system pressure. Failure to observe can resultin serious burns.

ATTENTION: Hot! Risk of burns. Wear safety goggles and heat‐protectivegloves.

1. Set motor speed of the unit feeding the material to 0 min-1; switch offmotor(s).

2. Place a container under the nozzle of the applicator.

3. Relieving pressure:

a. If the system is still supplied with compressed air: Activate thesolenoid valves electrically or manually (Refer to Figure 5). Do notuse sharp objects! Repeat this procedure until no more material flowsout.

b. If the system is no longer supplied with compressed air: The materialpressure in the applicator can be relieved only with the pressure reliefscrews of all of the filter cartridges. *Refer to page 34, RemovingFilter Cartridge.

OperationATTENTION: Allow only qualified personnel to perform the following tasks.Observe and follow the safety instructions in this document and all otherrelated documentation.

Triggering Solenoid ValveCAUTION: Trigger the solenoid valves only when the applicator is heated tooperating temperature!

Setting TemperaturesNOTE: The basis for temperature setting is the processing temperaturestipulated by the material manufacturer (usually 150 to 180 °C / 302 to356 °F). The maximum operating temperature of the product described heremay not be exceeded.

The applicator temperature required is set on the melter (maximum 200 °C /392 °F).

Setting Control Air PressureThe control air pressure is set to suit each application on an air conditioningunit. The air conditioning unit with pressure control valve is not part of theapplicator.

Set control air pressure:

Approx. 5 to 6 bar Approx. 0.5 to 0.6 MPa Approx. 72.5 to 87 psi

Nordson will assume no warranty or liability for damage caused by anincorrect pressure setting.

Setting Material Pressure

The material pressure is generated by the melter pumps. The maximummaterial pressure may not be exceeded:


Positioning Applicator

Coating Against Web Tension

NOTE: The optimum position of the applicator depends on several factors ofthe customer's specific application. Thus trial and error is the only way todetermine the best position. The fundamental differences are

� Application of material to closed-pore substrate

� Application of material to open-pore substrate

Continuous application

Open-pore Substrate Note

Closed-pore Substrate Figure 9

NOTE: To prevent unnecessary wear to the nozzle when material is appliedto open‐pored substrate or is applied intermittently to closed‐pore substrate,contact with the nozzle should not cause the substrate to deviate more than 1to 2 mm from a straight path.

The optimum angle of incidence of the applicator depends on variouscustomer-specific parameters. It is within the range of - 5° to + 10°.

The contact line (5 ) should be at the line at which the substrate (4 ) runs ontothe roll (3 ). The nozzle always has contact to the substrate (Refer to Fig. 10).

Ensure that contact is only on the dark gray segment of the coating roll (Fig.10, right); otherwise the applied material could drip.

� Application of material to open‐pore substrate (nonwoven)

� Application of material to closed‐pore substrate.

24 Applicator


Calculating Material Quantity

Sample Calculation

Nordson recommends following the sample calculation before starting up theapplicator and making a note of the application-specific values for applicationweight and width, substrate speed and pump output capacity in the tableCustomer-specific Values. These values can be used to calculate the pumpspeed and material quantity. Nordson also recommends entering results ofthe calculations in the table. This ensures that all values can be reproducedat any time.

NOTE: The material quantity for intermittent application is calculated thesame as for continuous material application.

Application weight (grammage) m = 20 g/m2

Application width of each material track b = 10 mm = 0.01 m

Substrate speed v = 500 m/min

Material quantity M = m � b � v = 20 g/m2 � 0.01 m � 500 m/min = 100.0 g/min

Output capacity of pump D = 2.4 g/revolution

Pump speed n = M � D = 100.0 g/min � 2.4 g/revolution � 42 rev/min

Customer-specific Values

Application weight (grammage)m

RepairATTENTION: Allow only qualified personnel to perform the following tasks.Observe and follow the safety instructions in this document and all otherrelated documentation.

Replacing Control Module


Nordson recommends keeping control modules on hand to avoidinterruptions in production (Refer to Parts List).

CAUTION: The control module is a high precision, valuable part. Handle verycarefully!

Removing Control Module

1. Relieve pressure.

2. Release the air connection and electrical connection.

3. Release screws (M4).

4. Use a suitable tool, e.g. a screwdriver, to detach the control module fromthe air bar (instant plug connection) (1, Fig. 17).

5. Extract the control module from the warm applicator.

Replacing Control Module (contd.)

Installing Control Module

NOTE: Required tool: Torque wrench.

1. Apply high temperature grease (Refer to Processing Materials, page 46)(Figure 18):

� To the O‐rings� To the screw threads� Under the screw heads.

2. Insert the new control module. Do not tilt! The control module ispositioned correctly when the cylindrical part rests evenly on the body,below the detection holes. The gap between the square part and thebody is then 2 mm. Also compare to the adjacent control modules or toFigure 18.

3. Screw in the screws by hand. Do not tighten yet.

Fig. 18

4. Alternately tighten the screws with a torque wrench, in three steps of 0.9Nm, until the maximum value of 2.7 Nm is reached.

5. Re-connect air and electrical connections.

NOTE: Observe the voltage stated on the ID plate of the solenoid valve.
