The belt, called Knuckleback, has a reinforced, reversed weld of the joint (knuckle) between the rod with each flat spiral wire end (back) to the preceding joint. This can reduce stretching and slag build-up during high temperature manufacturing and could also reduce the need for repairs. The weld is also designed to move the tension away from the weld point by knuckling the spiral wire prior to welding and allowing it to withstand wear longer. When used for sintering, the flattened spirals create a more uniform contact surface which helps remove excess carbon deposits and slag build-up.

“Cambridge has engineered metal conveyor belts for high temperature applications such as sintering for 50 years,” said Tracy Tyler, president and CEO. “We originally developed Knuckleback to provide a powdered metal manufacturer with a solution for its high maintenance costs and excess downtime.”

At high temperature applications over 1,700 degrees, extreme heat causes metal belts to stretch, requiring repairs that halt production. The Knuckleback metal conveyor belt can extend the belt life by strengthening and lengthening the connection between the belt’s spirals and rods.
