How to Use Fabric Primer and Cement for Hot Splicing of Rubber Conveyor Belts

When your conveyor belt system breaks it literally stops your operation in its tracks. Workflow is interrupted and goods cannot be produced or shipped. When this happens, plant operators must quickly evaluate the situation and determine the best course of action.

Not only must plant operators consider the fastest way to resume production, they must also evaluate whether a repair will be sufficient enough to preserve the life of the fabric conveyor belt.

Thankfully, advances in conveyor belt repair materials have made these deliberations easier. Hot splicing, fabric primer and cement are used to repair rubber conveyor belts.

In order to utilize these repair materials efficiently, it’s important to know how to use fabric primer and cement for hot splicing of rubber conveyor belts.

Damage to Rubber Conveyor Belts

Rubber conveyor belts have several layers that are vulnerable to injury that result from routine use.

The conveyor belt’s cover rubber is susceptible to abrasions, scoring and gouging. If left untreated, these injuries can lead to deeper cuts and holes that can affect the layer of fabric in between the top and bottom cover rubber.

The conveyor belt’s edges can shred or rip. When this occurs, frayed edges can get snagged as the conveyor belt moves on the track, damaging the belt even more.

Transversal rips diminish the strength of the conveyor belt and its capacity to carry the load of goods through the system.

How Does Hot Splicing Conveyor Belt Repair Work?

Hot splicing is an effective method of repairing rubber conveyor belts. To use this method, the damaged part of the conveyor belt is precisely trimmed. This can be done straight across or in a standard finger pattern, depending on the damage and type of conveyor belt.

Next, fabric primer is applied to enhance adhesion between the fabric and the rubber.

Fabric belt cover stock, an uncured rubber specially designed for hot splicing, is then inserted into the splice area. Hot splice cement is also applied to reinforce adhesion.

Then, the ends of the belt are fused by applying heat and pressure.

Once the hot splice is complete, plant operations can resume at normal capacity.
