How to Perform a Cold Cure Repair for Conveyor Belts

Posted in Conveyor Belts

Conveyor belt rips, gouges or worn spots need repair before the entire belt is damaged and needs replacement. While volcanized repairs are often the closest to manufacturer quality and strength on canvas belts, they require special equipment and time. Metal fasteners can also be used but do not offer the same strength as volcanized repairs. Another option is a cold cure repair, a quick and convenient method for some types of conveyor belt repairs.

What is Cold Cure Repair?

While volcanized repairs use heat and pressure to repair a portion of a conveyor belt, cold cure repairs use a chemical or resin process. This requires no special equipment like vulcanization, making it easier to perform quickly and wherever the conveyor belt is located. There are many different types of cold cures for belt repairs, designed for different materials and applications.

To perform a cold cure repair, the process is similar to volcanized repairs. The damage piece of belt is removed and a new piece of cover or canvas is cut to size. The difference is that chemicals or resin is used to adhere the new belt material in place instead of heat and pressure. The curing time depends on the product used but usually is about 4-8 hours. Compared to the downtime required to bring in volcanizing equipment and specialists, this can save days of missed production in some cases.

Time needed for repairs, whether cold cure or vulcanization, is always a concern. There is always a chance a repair will not hold and the time used will be wasted. It is a good idea to have a replacement belt available for serious damage – replacement time and cost can be a better option than the downtime costs for major belt repairs.
