Different belt jointing analyze for different conveyor belt materials
Apr 08, 2018

There is no doubt, all conveyor belts can be used only jointed to endless, so the belt joint is the most key points for the conveyor belts. The belt jointing quality affects the service life of belt, and determines the belt whether can be running smooth. Here some different jointing methods for different material of the belts. 

1. The jointing method.

Here is several different jointing method for the belt: mechanical jointing, cold bond jointing, hot vulcanized cover rubber, etc.

The mechanical jointing is refer to use the belt fastener, this jointing method is fast, convenience and economical. But it’s easy damage, low efficiency and will affect the service life of the belt. For the jointing of PVC & PVG solid flame retardant & anti-static belt, the mechanical jointing is applied for the belt low than 8 grade.

The cold bond joint is refer to use the cold bond adhesive. This jointing method has higher efficiency than mechanical jointing, it should has a better joint performance, but in practice, due to its difficult to master the process, plus the quality of adhesive has large affects to the belt jointing, so its not very stable.


The hot vulcanization jointing proved to be the most ideal of belt jointing, which has good features of high efficiency, stable, long service life, etc. But it also has shortcomings, such as complex process, high cost, time consuming, etc.

2. Belt jointing for plied textile conveyor belts: Above three jointing method is available accordingly to actual requirements.

3. Belt jointing for PVC & PVG solid flame retardant conveyor belt: The mechanical jointing is the common way due to the complex structure of that belt. But to ensure the jointing performance, hot vulcanization is needed for belt which is larger than 8 grade.
