Abstract
A suction gripper for lifting, transporting and depositing items, includes a basic suction body having an inner surface; a first opening for coupling the basic suction body to a suction source; and a second opening through which an item is introduced into the basic suction body by suction. An abutment member is positioned within the basic suction body between the first and second openings such that a clearance is defined between the abutment member and the inner surface of the basic suction body for allowing a suction stream to pass from the second opening through the clearance into the first opening. A storage chamber is defined between the inner surface of basic suction body, the second opening and the abutment member for accommodating an item drawn thereinto and held against the abutment member by suction.
