Use the following procedure to adjust the rewind tension or replace the slip clutch disk:
1. Remove all AC power and air to the applicator and remove the lower stainless cover.
2. Use
3
/
16
in. allen wrench to remove the screw [16A] at the end of the drive roller shaft.
3. Remove the Flat Washer, Spring Washer, and Compression Spring [16B] from the drive roller shaft.
4. If replacing the slip clutch disk, remove the Thrust Bearing [16C] and walk the rewind belt off the slip clutch pulley and
slide the pulley for the rewind off the drive roller shaft.
5. Clean the friction surfaces, replace clutch disk, and replace assembly.
6. If more rewind tension is needed, remove one washer from the inboard side of the spring keeper and re-install on the
outboard side of the spring keeper.
7. If less tension is needed, remove shim washer from the outboard side of the spring keeper and re-install on the inboard side of
the spring keeper.
8. Replace and tighten the screw on the end of the drive roller.
9. Replace the lower stainless cover and tighten the mounting screws.
10. Re-connect AC power and air to applicator.
11. Test the applicator and observe the rewind from beginning to end of a roll of labels.
12. Re-adjust if necessary.
Drive Belt Adjustment
1. Remove all AC power and air to the applicator.
2. Remove the lower stainless cover and rotate the applicator so the nip drive roll assembly is facing the floor. This orientation
helps when setting angular alignment.
3. Remove the air lines interconnecting the two sides of the applicator to gain access to the drive belt.
4. Remove both splice plates that are mounted on either side of the motor. Use a
5
/
32
in. Allen wrench to remove the (12) screws
holding the splice plates. There are enough remaining screws to keep rewind and applicator plates in place.
5. Discard broken/worn belt and check pulley integrity and alignment. The motor pulley hub should extend beyond the motor
shaft approx.
1
/
16
in. The 3in. main drive pulley dimensioning should be
45
/
64
in. from the backside of the 360y faceplate to the
inside edge of the pulley.
6. Place replacement belt onto flanged motor pulley. Cautiously/slowly walk the belt over the main drive pulley to keep from
crimping or nicking the belt’s edge.
7. Loosen the (4) screws on the side of the motor mounting plate using a
5
/
32
in. allen wrench.
8. Push the motor mount assembly upward and re-tighten mounting screws. Ensure the motor assembly is 90° from the
faceplate to ensure proper angular alignment.
Verifying Angular Alignment
a. Place 2 pcs. of ½ in. wide x 0.025 in. thick banding material/strapping cut approximately 8in. long between the
Faceplate and the Motor Mount Side Frames.
b. Place your hand on the end of the Motor and firmly push the Motor toward the Faceplate, making sure the Motor
Mount Side Frames are running parallel to the Faceplate.
c. Verify that the belt tension is correct, see Step 11 below. Snug the (4) screws, remove banding strips, and finish
tightening the (4) screws.
9. Disengage nip roller and turn the drive roller. Ensure there is no severe catching as you turn the roller.
10. Check the belt tension. With light finger pressure on one side of the belt, adjust the tension so the belt deflects approximately
1
/
16
in. to
1
/
8
in.
NOTE: Do not over tighten the belts. This may result in shortened motor life. If the belts are too loose, label stop may
become erratic.
11. Replace the two splice plates and replace the air lines interconnecting the two sides of the applicator.
12. Replace the stainless cover and tighten the mounting screws.
13. Re-connect the AC power and air.
