Drive Pulley Lagging the importance of proper technical

The tension in a conveyor belt decreases as the belt travels around the drive pulley causing the belt to contract In order to prevent slip the lagging must deform circumferentially to match the belt contraction The belt traction force causes this lagging deformation but if beyond the limit friction will allow slip As the belt contracts it
