Abstract: A suction gripper has a driver that is a compressed-air source. The suction gripper has a suction opening opened up by a pipe section forming a suction section. At a distance from the suction opening, a convex surface is arranged spaced from the suction section by an annular outlet. The suction gripper has a central channel formed in a central well. The central channel has a first opening opened up by a convex surface around the central channel. The central channel adjacent to the convex surface has its smallest cross-section and from this broadens towards the second opening opposite the first opening. In a particular suction gripper, the annular outlet is formed by a section of the convex surface spaced radially from the longitudinal axis of the central channel and by a shoulder spaced axially thereto, which covers the convex surface at least in an annular region.
