Vulcanized Conveyor Belt Splices Part 3

Vulcanizing can be more difficult and less reliable on older, worn belts. In applications on conveyors that are utilized in the process of transporting hot materials, it is important that all material be discharged from the belt prior to stopping the belt. Hot material left on a stopped belt can "bake" a splice and reduce its life.
