Pulley lagging sheet is generally applied to the surface of a pulley to increase the friction between the pulley and the conveyor belt. It is typically made of rubber, but can also be made of other materials. The purpose of pulley lagging is to improve the grip between the belt and the pulley, which reduces slippage and improves the efficiency of the conveyor system. It also helps to protect the surface of the pulley from wear and damage. Installation of pulley lagging is typically done by gluing or bonding the lagging material to the surface of the pulley. It is important to ensure that the lagging is properly aligned and evenly applied in order to achieve maximum performance and longevity.
