Abstract:
A device to convey suspended, plate-shaped work pieces or metal sheets, said device comprising:at least one conveyor belt (1) revolving around a retaining device (3) for conveyance of work pieces (W) adhering thereto; a controllable or regulatable device (6) for generation of negative pressure, said controllable or regulatable device (6) serving to retain the work pieces on the conveyor belt (1) and having an opening plane (22) defined by suction ports (7) that is recessed from the retaining device (3) at a distance (A) in relation to a conveyor plane (F) created by an exterior side of the conveyor belt (1) so that a gap (Z) is produced between a work piece (W) adhering to the conveyor belt (1) and the opening plane (22) and the work piece (W) is held on the conveyor belt (1) by a negative pressure that is created in the gap (Z), wherein a device (8, 23, 25, 26, 29, 30, 32) for ventilating the gap (Z) is provided so that the work piece is retained on the conveyor belt (1) by dynamic negative pressure.
