When the belt goes from “flat to troughed” or “troughed to

belt exceeds the central line of travel. As edge tensions of the belt are increased, the belt and belt fabric must either stretch or travel at a much higher speed to complete the transition. This edge tension can be kept within safe limits if proper transitions are used with the conveyor systems.

Definitive Guide for Choosing the Right Conveyor Belt

Dependent on your system, most of the wear occurs on the top surface of your conveyor belt and a smaller amount on the bottom cover. The quality of the belt cover is a very important factor in ensuring that the top surface remains in good working order for the long-term sustainability of your conveyor belt.
