Conveyor belts transition from flat to troughed | Maritn ...

On a typical conveyor, the belt is troughed for the carrying portion of its journey and returned to a flat configuration for the return run. Consequently, at a terminal (head or tail) pulley, the belt must be converted from flat to troughed shape or from troughed back to flat. This changing of the belt's profile is commonly called the transition.
