  • Patent number: 6422377
    Abstract: A band conveyor device used for the suspended transport of plate-like workpieces, metal sheets or the like and has a conveyor belt which is moved along a holding track. A vacuum device holds the goods to be conveyed by suction against a transport side of the conveyor belt. The vacuum device has a multiplicity of suction nozzles which are disposed on the holding track at the transport side of the conveyor belt, so that their nozzle edges which point towards the transported goods to be conveyed are situated at a short distance from the goods. The air necessary for holding the goods is drawn through local, separate invariable vacuum zones, through which the goods pass in succession along the transport path.
