The equipment design has dictated the need for belts to operate in high-temperature applications, in situations where heat and/or wear will cause other types of belts to stretch; in operations requiring the drive to operate in both horizontal and vertical planes, where belts must bend, twist, or perform at right angles in confined spaces, round woven belts are filling the bill. Belts of spun polyester with urethane dipped coverings provide flexibility and vibration-free operation.
