What is a Finger SPLICE?
For Finger Splices, plies are split or separated, fingers are cut and matched, and lap areas fused or thermo-welded together. This result is a tight, strong flexible endless splice belt. Finger splices can be performed on an air-cooled or a water-cooled press. This method is especially suitable for single-layered belts.
STRAIGHT FINGER SPLICE PROCESS
- STEP 1: A zigzag pattern is punched into both sides of the belt, creating several interlocking “fingers.”
- STEP 2: These fingers are carefully and tightly aligned on the press.
- STEP 3: A silicone matrix layer is added on top of the belt
- STEP 4: The pressure, temperature and dwell time are set and the press is closed.
- STEP 5: After the belt is vulcanized release the press and trim off any shims that were used.
BENEFITS OF FINGER SPLICING
- Produces highest tensile strength bond
- Reduces noise
- Great for the food industry.
The welding process seals the belt (cords and fibers) eliminating any places for germs to hide. - Maintains the surface integrity of the belt
- No plastic or metal parts to break off
- Basically disappears on the belts surface.
