  "abstract": "A bellows-cup vacuum gripping tool comprising one mounting flange, four bellows cups, one ejector, one manifold, one pressure sensor and one blow-off valve. When the bellows cups reach the workpiece, the bellows cups are evacuated by the ejector. After the workpiece has reached the set-down position, the workpiece is blown off by the blow-off valve. The arrangement is a proposed configuration composed from a typed library of mechanism blocks derived from published patents; it has not been constructed.",
