FINGER SPLICING, REPAIR, AND INSTALLATION OF FABRIC CONVEYOR BELTS

FINGER SPLICING, REPAIR, AND INSTALLATION OF FABRIC CONVEYOR BELTS

Finger splicing is an advanced joining technique that cuts the belt ends into interlocking finger-shaped sections to achieve maximum strength and flexibility.

Finger Splicing Methods

• Geometric Cutting: The belt ends are cut into interlocking "fingers" to distribute working tension evenly.
• Structural Advantage: It avoids aggressive straight cuts and maintains the same belt thickness without creating bumps or vibrations on the rollers.
• Vulcanization: The fingers are joined by applying heat and pressure (hot vulcanization) or special chemical adhesives (cold vulcanization), achieving high tensile strength.

Repairs and Maintenance

• Patches and Local Vulcanization: Restoration of tears, punctures, or surface wear on the rubber or PVC cover.
• Section Replacement: Replacement of damaged sections by inserting new segments joined through vulcanization or temporary metal fasteners.

Installation and Assembly

• Alignment and Tensioning: Initial installation or belt replacement on the structure, ensuring proper centering to prevent rubbing or material spillage.
• Performance Testing: Verification of belt movement under no-load and loaded conditions to ensure splice service life.
