Abstract
A handling bar for laminated or film supports, such as paper, is disclosed, including a hollow tubular body provided with an inner cavity and an outer side surface, a plurality of through holes, arranged on the tubular body to put the inner cavity in contact with the outer side surface. The handling bar also includes at least one connection to a compressed air source or a suction device, where the connection is shaped for the inflow of compressed air or to suction air into the cavity and at least one filtering element arranged inside the tubular body where at least at one portion of the holes filters the air passing between the inner cavity and the holes.
