larger image These idlers automatically maintain been alignment on one-way or reversible belt conveyors. When a belt travels off-center, the belt edge contacts one of the vertical guide rolls which activates a brake to retard rotation of the adjacent inclined end roll This creates a drag between roller and belt, swiveling the idler about its central axis in the direction of belt travel. This action automatically realigns the belt.
