Reversing conveyor In a reversing processing conveyor, the direction of rotation of the driven rollers are changed frequently. Consequently this additional inertial forces for accelerating or decelerating the roll- ers and the load have to be taken into consideration. The maximum peripheral acceleration, 'a' of the roller is kept within limits, such that the load weighing G. moves on rollers without sliding (also called skidding). There will be no sliding when the frictional force between roller and load is more than the inertial force required to accelerate the load. If uo' is the static coefficient of friction then,
