Abstract
A pneumatically actuated area vacuum gripper for gripping and, if necessary, separating workpieces is provided by the present disclosure. In particular, the vacuum gripper is used with thin, flexible workpieces, and has a suction chamber, which has a suction wall with perforations, to be placed on the workpiece. An ejector nozzle has a connection and an outlet, the ejection nozzle being connected to the suction chamber via its connection, and the outlet of the ejector nozzle opening to the outside or into an exhaust air duct, and the suction inlet of the ejector nozzle empties into the suction chamber, whereby the direction of the air stream in the connection coming from the suction chamber corresponds to the direction of the main air conveyance in the ejector nozzle.
