What are the common methods for joining or splicing mesh conveyor wire belts

Joining or splicing mesh conveyor wire belts is a critical aspect of conveyor system maintenance and repair. Proper splicing ensures that the belt remains continuous and functional. The method used for joining or splicing depends on the specific type of belt, the application, and other factors. Common methods for joining or splicing mesh conveyor wire belts include:

1. Wire Hook Fasteners: Wire hook fasteners are commonly used for joining mesh conveyor wire belts. These fasteners consist of pre-formed wire hooks that are inserted into the mesh openings and bent over the adjacent wire to secure the ends together. They offer a reliable and adjustable connection.

2. Clinched Loops: Clinched loops are created by bending the wire ends of the belt to form loops and then securing these loops together using a pin or a crimped connection. Clinched loops provide a strong connection and are often used in heavy-duty applications.

3. Lacing Pins: Lacing pins are metal pins that are inserted through the ends of the belt and secured with a cotter pin or a lock. They offer a relatively simple and effective way to connect the belt ends.

4. Alligator Lacing: Alligator lacing consists of pre-punched plates with teeth that are inserted into the mesh openings of the belt. The plates are then compressed together with a special tool to secure the belt ends. Alligator lacing is suitable for various belt types and offers a strong connection.

5. Overlapping Spiral Loops: For belts with round spiral wires, overlapping spiral loops can be used. This method involves overlapping the ends of the spiral wires and securing them with crimped or bolted connections. It's suitable for belts with larger wire diameters.

6. Butt Welding: In some applications, butt welding can be used to join the belt ends. This involves welding the ends of the wires together to create a continuous connection. Butt welding is suitable for certain metal belt types.

7. Clipper® Wire Hooks: Clipper® wire hooks are designed for easy installation and are used to join mesh conveyor wire belts. They offer a secure connection and can be used in various applications.

8. Butt Joint Welding: For metal belts, butt joint welding involves welding the belt ends together. This method is suitable for belts with a sufficient number of solid wires.

9. Thermoplastic Welding: In applications where hygiene is crucial, thermoplastic welding can be used to join the ends of plastic modular belts. This method uses heat to fuse the belt ends together.

The choice of splicing method depends on factors such as the type of belt, the application, the ease of maintenance, and the expected load on the belt. It's essential to follow manufacturer recommendations and industry-specific guidelines for splicing to ensure the durability and reliability of the connection. Regular inspection and maintenance of splices are also important to prevent issues and downtime.
