The device including an external suction box having first and second openings located adjacent a deflection roll and adjacent to a lift-off point associated with a first dryer cylinder, respectively. The external suction box also including a first and second aspiration conduit respectively associated with the first and second openings. The deflection roll may be aspirated by an external vacuum souce coupled to the external suction box. The fibrous sheet, through the support belt, may be assisted at the lift-off point by aspiration by a separate external vacuum source coupled to the second aspiration conduit.
