  • Patent number: 4483527
    Abstract: Disclosed is a sheet handling device comprising an unprocessed sheet material storage box, a processed sheet material storage box located therebelow, and a suction device which may be telescopically moved between the sheet material storage boxes and a work table onto and from which the sheet material is to be fed and taken out by means of suction cups provided on the lower surface of the suction device. To keep the state of the sheet material in transit under control, a plurality of nozzles are provided along the suction cups for blowing air along the sheet material. Since the two sheet material storage boxes are arranged one over the other and there is no rail extending over the work table, very little floor space is taken up and the work performed on the work table is not hindered by the sheet handling device.
