How To Splice Conveyor Belt

Splicing a conveyor belt is a process used to join two ends of a conveyor belt together. This is typically done when a conveyor belt is damaged or needs to be extended. There are several methods for splicing conveyor belts, and the choice of method depends on factors such as the type of belt and the application. Here are some common methods for splicing conveyor belts:

Mechanical Fasteners:

Using mechanical fasteners is a popular and straightforward method. It involves attaching metal or plastic plates with hooks or hinges to the ends of the belt. The plates are then connected to each other, holding the belt together.


Vulcanization is a heat and pressure-based splicing method used for fabric and steel-cord conveyor belts. It involves heating the ends of the belt with a vulcanizing press and bonding them with heat-resistant adhesive materials. This method creates a strong and durable splice.

Cold Bonding:

Cold bonding is an alternative to vulcanization, and it uses adhesive materials to bond the belt ends without heat. It's suitable for certain types of conveyor belts and allows for splicing without the need for specialized equipment.

Overlapping and Securing with Clips:

For lightweight conveyor belts, you can overlap the ends and secure them with belt clips. This method is less suitable for heavy-duty belts.

Step Splice:

In a step splice, the ends of the conveyor belt are cut at an angle. Then, they are joined together by overlapping and bonding with adhesive or vulcanization. This type of splice is used for belts with small pulley diameters.

Finger Splice:

Finger splicing is used for flat or troughed conveyor belts with fabric plies. It involves cutting the belt ends into a pattern of fingers and bonding them with adhesive or vulcanization. This creates a strong and flexible splice.

When splicing a conveyor belt, it's essential to follow the manufacturer's guidelines and safety precautions to ensure a secure and reliable splice. Proper preparation of the belt ends, accurate cutting, and the correct choice of splicing method are critical for a successful splice.
