2.1 Description of Machine

The Hysol

Wheel Coater (98038) is a bulk hot melt adhesive transfer machine. The Hysol

Wheel Coater is used to apply a continuous film of hot melt adhesive to the surface of a part.

The Wheel Coater is made up of an adhesive reservoir (6.5" wide x 10" long x 2" deep), three

350-watt heaters and a transfer roller, which is driven by a variable speed electric motor. The

thickness of the adhesive film is fully adjustable and a thermometer is used to indicate reservoir

temperature. The variable speed motor and film thickness control greatly contributes to increase

productivity of hot melt adhesive applications.

2.2 Theory of Operation

The adhesive is applied by passing the surface of the part over a rotating roller. A thin film of

adhesive is transferred from the roller to the part. The roller is six inches in length and is partially

submerged in a pool of molten adhesive. With each rotation the roller is recoated. The transfer

surface, of the roller, is knurled to hold a greater volume of adhesive. The thickness of the

adhesive is controlled by means of an adjustable blade doctor. The adhesive temperature and

the viscosity of the adhesive formulation also affect the thickness of the film.

5 Operation

5.1 Set Up

• Place the Hysol

Wheel Coater on a level, heavy-duty bench and preferably one with

adjustable legs.

• Adjust the height of the table so the working height of the machine is comfortable.

• Plug the power cord into a properly grounded 120V, 15-amp outlet.

5.2 Start Up

• Fill reservoir to a depth of 1" minimum and 2" maximum. Do not fill above the

⁄2" ledge near

the top of the pot. Maintain the level within this range during operation.

• Turn rotary switch, on motor speed control (item 2), to the off position.

• Plug power cord into properly grounded 120V, 15 amp outlet.

• Flip toggle switch (item 1) to “ON” position. Red indicator light will come on.

• Allow machine to warm up 30 minutes. Observe thermometer.

• Add additional pellets as required to bring the fill level to between 1" and 2" deep.

Caution! DO NOT ATTEMPT TO ACTIVATE THE COATING ROLL BEFORE OPERATING

TEMPERATURE IS ATTAINED. To do otherwise, will cause a motor overload, which will

blow the fuse (F1).

• Turn rotary switch, on the motor speed control, (item 2) clockwise to start the roller turning

slowly. For a new unit it may be necessary to turn the rotary switch 50% of scale to start

rotation. Turn the switch to a higher number to increase the rate of rotation.

5.3 Shut Down

• Always turn off the motor speed switch first. This sequence will help ensure that the roller is

not accidentally started with a cold machine.

• Flip the power switch to the “Off” position.

5 Operation (continued)

5.4 Film Thickness Adjustment

• Adjusting the clearance between the doctor blade and the roller can change film thickness on

the roller.

• Loosen the 4 machine screws, which secure the doctor blade.

• Place a feeler gauge between the roll and blade at one end of the roll.

• Tap the blade lightly against the feeler gauge.

• Lightly snug the end most screw.

• Move the gauge to the other end of the roll and repeat.

• Snug all four screws down. Do not over tighten.

5.5 Temperature adjustment

• The operating temperature of the machine is factory set at 375°F. This setting should be

sufficient for most EVA adhesives. For other types of adhesives refer to the data sheet for the

adhesive application temperature or call Technical Service for assistance.

• The temperature thermo switch set point shaft is not intended for operator adjustment and is

accessible only by removing the sheet metal cover from the adhesive pot. The thermo switch

is located at the roller end of the reservoir.

• A quarter-turn clockwise of the set point shaft will increase the operating temperature about

75°F. Wait at least 15 minutes for the temperature to stabilize. After 1 hour of operation, check

the temperature again.

Notice: Do not exceed 450°F.

☞

6 Care, Cleaning, and Maintenance

6.1 Char Removal

If the Hysol

Wheel Coater is over heated a brown or black flaky crust will form on exposed

surfaces of the glue pot. This is charred adhesive that can be removed using the following

procedure.

• Wear heat resistant leather gloves.

• Warm the machine to operating temperature.

• Pour out excess adhesive.

• Scrape off excess adhesive and char with a wood tongue depressor.

• Allow machine to cool.

• Use a paintbrush to apply a coating of solvent-based paint remover to remaining char.

• Allow paint remover solvent to soak on the char. It may be necessary to allow paint remover

to soak overnight.

• Remove softened char and reapply paint remover as required.

6.2 Clutch
