Abstract
A gripper to grip a workpiece includes a body with a flat gripper surface. The gripper surface includes a plurality of openings that are distributed over the gripper surface, each of the openings connectable to a source of suction. At least one flow restrictor is located between the plurality of openings and a connector of the gripper to the source of suction to restrict the inflow through each opening of the plurality of openings. When the suction is applied to the plurality of openings and a part of the workpiece surface covers at least one opening of the plurality of openings and another of the openings remains uncovered, the suction force at the covered opening is sufficiently strong to grip the workpiece surface.
