Conveyor Belt Repair
Section 1: Preparation

General Preparation of the Dual Cartridge/Dispenser/Mixer Tip Assembly:
    1. Select the desired dispenser (manual or pneumatic) and the mix tip.
    2. Cut the blind-end off of the cartridge orifice, or remove the cap.
    3. Place the cartridge in the dispenser.
    4. Dispense just enough material so that both components dispense equally.
    5. Assemble the mix tip onto the cartridge.

    Preparation of Repair Area
    Note: The PBI-PU5000 “Belt-Band-Aid” repair kit is a primer less system which cures at room temperature. For optimum results, it is recommended that cure be accelerated with heat.

    Preparation of Repair Area for Splicing

    1. Clean repair area thoroughly with acetone* at least 6 inches beyond the repair area to remove any contaminants from the area to be repaired. Allow to dry.
    2. After cutting the belt for the splice, use normal skiving procedures to skive the belt 5-6 inches on both sides of the cut.
    3. Use a template to mark holes for the clips.
    4. Punch the holes out manually or use an impact wrench.
    5. Bevel both sides of the splice.
    6. Use a coarse sanding disk to grind 2-3 inches beyond the repair.
    7. Remove all grinding debris with compressed air. Make sure air lines are dry.
    8. Clean thoroughly about 2 inches beyond the ground area with acetone.* Allow to dry 20-30 minutes at room temperature.
    9. Attach clips to all holes.
    10. Use duct tape to keep The PBI-PU5000 “Belt-Band-Aid” off of the clip hinges.
    11. Use duct tape to dam both sides of the belt area to be filled. *Note: When using solvents, be sure to extinguish all ignition sources and follow the manufacturer’s precautions and directions for use.

Section 2: Application

Room Temp Cure
  1. Fill the cut out section and be sure to apply material to ground sections on the surface. Use a spreader to spread The PBI-PU5000 “Belt-Band-Aid” into ground areas. Do not apply or spread beyond the scuffed areas. Use masking tape to keep The PBI-PU5000 “Belt-Band-Aid” off of the non-scuffed areas. Note: When applying The PBI-PU5000 “Belt- Band-Aid” on a tilted or non-horizontal surface, use a spreader to keep working the PBI- PU5000 “Belt-Band-Aid” kit into the void.
  2. Allow to cure at room temperature for 2 hours or use heat cure to accelerate the cure.

Heat Cure

  1. Fill the cut out section and be sure to apply material to ground sections on the surface. Use a spreader to spread The PBI-PU5000 “Belt-Band-Aid” into ground areas. Do not apply or spread beyond the scuffed areas. Use masking tape to keep The PBI-PU5000 “Belt-Band-Aid” off of the non-scuffed areas. Note: When applying The PBI-PU5000 “Belt- Band-Aid” on a tilted or non-horizontal surface, use a spreader to keep working the PBI- PU5000 “Belt-Band-Aid” kit into the void.
  2. Apply heat (heat gun or preferably a heat tunnel) to the area of belt that was repaired, including the 2-3 inches ground on both sides. In a heat tunnel, temperature should be 170°F (76°C) for 20 minutes or 250°F (121°C) for 5 minutes. (A heat tunnel can be easily made with air conditioning duct.) If a heat gun is used, heat on HIGH for 20 minutes. Hold the gun 6-8 inches above the belt and use a constant back-and forth motion to distribute the heat evenly.
  3. Let the repair cool to room temperature and remove all damming duct tape.

Preparation of Repair Area for Gouges and Holes Note: Repairing gouges and holes are done in the same manner with the exception that repairing holes requires the extra step of damming the bottom of the belt as stated in Step 4 below. When repairing gouges, skip the following Step 4.

  1. Clean with acetone* to remove any contaminants from the area to be repaired. Thoroughly dry the surface.
  2. Bevel all around the gouge or hole. Use a coarse grinding disk to grind 2-3 inches beyond the edges of the gouge or hole. Use compressed air to remove all grinding debris. Make sure air lines are completely free of moisture.
  3. Clean thoroughly about 2 inches beyond the ground area with acetone* to remove any contaminants from the area to be repaired. Allow to dry 20-30 minutes at room temperature.
  4. The PBI-PU5000 “Belt-Band-Aid” is to be used on a hole in a belt, bevel both the top and bottom of the hole and use duct tape to dam the bottom of the belt.

*Note: When using solvents, be sure to extinguish all ignition sources and follow the manufacturer’s precautions and directions for use. Application to Gouge/Hole Repair Area.

  1. Fill the gouge or hole with The PBI-PU5000 “Belt-Band-Aid” and also apply The PBI-PU5000 “Belt-Band-Aid” to the ground edges.
  2. Use a spreader to spread the PBI-PU5000 “Belt-Band-Aid” into the ground edges. Use masking tape to keep The PBI-PU5000 “Belt-Band-Aid” off of the non- ground areas of the belt.
  3. Allow to cure at room temperature for two hours or use the heat-cure method previously described to accelerate the cure.
  4. Let the repair cool to room temperature and remove all damming duct tape.
