Splicing of conveyor belts
HOT SPLICING OF CONVEYOR BELTS
FINGER SPLICE
- Primarily used for thermoplastic belts with 1 ply.
- Advantages:
- Excellent flexibility and high strength.
- Eliminates the need for mechanical fasteners.
- Reduced operational noise.
- Eliminates product accumulation points.
- Enables easy cleaning and meets hygiene standards.
FOLD-BACK FINGER SPLICE
- Used when a traditional finger splice is too sensitive to damage.
- Key Characteristics:
- A double layer of fingers increases strength.
- Prevents finger puncture due to belt misalignment.
- Extremely reliable in harsh operating conditions.
- The optimal solution for long-term use.
STEP SPLICE
- Offers the highest strength among hot splices.
- Applications:
- Extremely demanding working conditions.
- Troughing systems (idlers).
- Food industry.
- Long belts for bulk materials (sugar, salt, powders).
MECHANICAL SPLICING OF CONVEYOR BELTS
PROPERTIES OF MECHANICAL SPLICING
- A detachable joint – suitable for frequent maintenance.
- Applications:
- Belts requiring frequent cleaning.
- Conveyors that are frequently relocated.
- Rapid belt installation/replacement.
- Versatility: Can be installed on various belt materials.
TYPES OF MECHANICAL FASTENERS
- Hinge Pin / Plate Fasteners
- Solid Plate Fasteners
- Bolt-Hole / Staple Fasteners
FACTORS FOR FASTENER SELECTION
- Machine construction (pulley diameter).
- Operating conditions.
- Type of product being transported.
- Conveyor belt thickness.
INSTALLATION PROCESS
- Uses tools ranging from simple (hammer, wrench) to pneumatic tools.
- Note: A mechanical splice has lower strength compared to a hot splice.
