These belts are manufactured in 2 or 3-ply construction with cut edges and carcass of NN or EP fabric. The surface texture resists the tendency for the material to roll back down from the conveyor. The top cover consists of wear-resistant rubber with an anti-slip surface. It provides a cushioning effect on top which absorbs vibrations and impacts acting on transported materials. Rough top belts are manufactured either with a bottom cover or bare back for slider bed applications used in transportation at inclination angles of 25 – 30 degrees on level or slope surfaces.
