belt moves onto the pulley the tensions must equalize quickly across the belt width and “belt creep” in the low tension areas can occur. Adequate transition distances are extremely critical with the use of today’s high modulus, low stretch, conveyor belt carcasses. The stresses resulting from a short half trough transition distance at the

Ten common mistakes in conveyor specification and design

6 Insufficient edge sealing distance. The free belt edge outside of the skirtboards in the loading zone of a conveyor is called the edge sealing distance. The CEMA standard is based on the distance between the inside dimensions of the skirtboards being equal to 2/3 the flat belt width, which does not account for the toughing angle.

3 Basic Conveyor Belt Tracking Rules To Follow Accurate

Conveyor belts on installations, where the belt width is equal or larger than the conveying length, are increasingly difficult to guide. Namely thin belts with little lateral stiffness, particularly at high speed, have a tendency to buckle and potentially fold over when fitted on short conveying distances
