1) NOTE: Valve #5 is a normally open shut-off valve for models

beginning with Serial #7132 (manufactured on10-28-80)

2) Numbers appearing here refer to valve numbers on Valve Flow Diagram.

OPERATION

1) Open the storage tank cover.

2) Set the multi-port valves to fill the storage tank from the drum as shown. To reduce fill time, turn the

air regulator adjustment knob clockwise increasing adhesive flow. (This operation need only be repeated

when the level of the adhesive in the storage tank is low and is being replenished. Keep the 55 gallon

adhesive drum for later use as a water bath during clean-up.) See Fig. B.

3) Remove the storage tank cover. Stir the adhesive in the storage tank with a paddle or long wooden

handle after removing the cover.

4) Set the valves so that the adhesive circulates to the trough from the storage tank as shown. Turn the

air regulator knob counter clockwise (decreasing adhesive flow). Allow the adhesive to slowly spillover the

spillgate into the storage tank during operation.

5) To regulate the amount of adhesive applied to the liner, turn off the power and lift the safety guard on

the material entry side of the Roto Bonder. Raise the feed table and allow the table to drop perpen-

dicular toward the floor. Turn the Selector Knob Assembly to the "Clean" position. With the power on,

look into the machine. Do not put your hands into the GBAC. Turn the Metering Wheel (clockwise to

decrease-counter clockwise to increase) to adjust the amount of adhesive that coats the adhesive roll.

For maximum efficiency, the adhesive roll should be coated with a thin even coat of adhesive. With power

off, replace the feed table and return it to its proper position. See Fig. C and D.

6) Switch the power on.

7) Adjust the GBAC for liner thickness by moving the Selector Knob Assembly [clockwise to increase (thicker

liner), counter clockwise to decrease (thinner liner)] to adjust the roll clearances. See Fig C.

8) Feed the pre-cut fiberglass liner material into the Roto Bonder. Coated material is automatically carried

through to the exit fingers.
