Reutov A.A., Ivanitsky R.B., Emanov S.L. Determination of the belt location on the support rollers of conveyor curved section. Two models are proposed for calculation belt lateral displacement at the conveyor curved section. It is shown that calculation without taking into ac-count the belt bending stiffness, even on slightly curved section of the conveyor, leads to signifi-cant errors. The application support roller, spring-loaded on the one side, is impractical to reduce belt lateral displacement at the curved sections of the route.
