Abstract
In a sandwich-belt conveyor there are tow belts, one is driving belt and another driven belt, used to pinch and convey media. Finite elements analysis and experiments are carried out in this paper for investigating belt tensions and slip of belt and pulley. The cross sectional structure of real rubber belts is considered in the FEA. It is found that the gross slip between the two belts will influence the belt tensions, but the position of pitch line of the belt does not. Also it is found that the speed delay of pulley and belt of driven side is made up of two parts: bending slip due to belt bending and elastic slip due to torque load.
